About Revit Architecture Projects

An AutoCAD project typically consists of a set of drawings, such as floor plans, elevations, sections, and schedules created as 2D graphics.

A Revit Architecture project consists of a single file that contains all the 2D and 3D views and documentation related to the building design.

Definition of a Revit Architecture Project

A Revit Architecture project is a complete 3D representation of an architectural design together with associated construction documents such as details and schedules. The information related to the building model is represented in 2D and 3D views and schedules stored in a single project file.

A Revit Architecture project consists of the following:

■ Project environment■ Components and views

Project Environment

When you design a building model in Revit Architecture, you also define the project environment. You manage the project environment from the Project Browser. The project environment includes the views and visibility settings of the building model components. A new project is usually created from a project template. Views, such as floor plans, ceiling plans and elevations, are automatically loaded into the Project Browser depending on the chosen template. The project environment settings are saved with the project, and you can customize them at any point in the design process.

Components and Views

The Revit Architecture project environment provides components and views for creating a building model. You can add parametric building components to a project such as windows, doors, and walls. You can also create views, such as plan, section, elevation, and 3D views. If you make any changes to a view, all views are automatically updated to reflect the change. All views are organized in the Project Browser. The view that you activate in the Project Browser is displayed in the view window.

AutoCAD Data in Revit Architecture

AutoCAD data provides base vector drawings that you can use as references in Revit Architecture. To use AutoCAD data, such as details, note blocks, or plans, in your Revit Architecture projects, you must either link or import the data.

Linked AutoCAD Drawings

Linked AutoCAD drawings in Revit Architecture behave like xrefs in AutoCAD. Changes that you make to the data in the linked AutoCAD drawing are updated in the Revit Architecture project whenever the link is reloaded.

You can link the following types of AutoCAD data:

■ Details■ Note blocks■ 2D and 3D toposurface maps■ Legends

You can link an AutoCAD drawing to a view in your Revit Architecture project and place it on a sheet. You can use section tags, detail tags, and callout tags to reference the view. All of the associated AutoCAD drawing information remains linked to the Revit Architecture project.

You can also acquire and publish coordinate systems between Revit Architecture and AutoCAD to synchronize the Revit Architecture coordinate system with the AutoCAD coordinate system. You should link AutoCAD data in workflows where some project work will be done in AutoCAD and you wish to update any changes to the AutoCAD drawings in the Revit Architecture project.

Sample Chapter



esale


Imported AutoCAD Drawings

You can also import an AutoCAD drawing into Revit Architecture. When you import AutoCAD drawings into Revit, no link is maintained with the original drawing and any changes made in AutoCAD are not reflected in Revit. You can snap to and trace over the imported AutoCAD drawings to create Revit Architecture project components. You should typically import drawings that do not need to be updated from AutoCAD like standard details or backgrounds and profiles for Revit Architecture family objects.

Process of Creating a Project with AutoCAD Data

Before you leverage your AutoCAD data to create a Revit Architecture project, you need to create levels and views in Revit Architecture into which you will import or link AutoCAD data. You may also need to prepare an import line weights text file to correctly map dwg/dxf pen colors to corresponding Revit Architecture line weights.

Process: Creating a Project with AutoCAD Data

The following steps describe the process of creating a project with AutoCAD data.

1. Create views.

Create views to correspond to AutoCAD drawings that you want to import or link to your Revit Architecture project.

2. Import or link AutoCAD drawings.

Import or link the AutoCAD drawings to Revit Architecture views, such as floor plans or drafting views.

3. Snap to and trace the AutoCAD geometry.

Snap to and trace the AutoCAD geometry to create your building model.

4. Make changes to the linked drawings.

Make any necessary changes to the linked detail drawings in AutoCAD, if required. The changes are updated automatically the next time you open your Revit Architecture project.

Guidelines for Creating a Revit Architecture Project with AutoCAD Data

Many Revit Architecture users already have a lot of knowledge and legacy data from AutoCAD. This knowledge and data can be leveraged in a Revit Architecture project for greater efficiency. For successful creation of a Revit Architecture project using AutoCAD data, follow these guidelines.

■ Import or link AutoCAD drawings that contain geometry you can snap to and trace over.■ Use an Import/Link mapping text file to import pen numbers from a DWG™ or DXF™ file and

map them to a Revit Architecture line weight. ■ Use the Import/Link dialog box to determine the color, placement, and scaling of imported

geometry. ■ You can import or link AutoCAD drawings that contain 2D geometry, which you can use directly

on a sheet for plotting. You can also modify AutoCAD geometry in Revit Architecture by exploding and changing line work or layer and text properties.

■ You can leverage AutoCAD drawings as backgrounds for creating Revit Architecture projects or components. You can also import note blocks and titleblock geometry from AutoCAD.

■ Use the Manage Link dialog box to manage the loading and unloading of DWG files. Also use the object styles dialog box to keep track of imported DWG files.

Lesson: Migrating Project Standards

Overview

This lesson describes how to maintain AutoCAD project standards when you migrate drawings from AutoCAD to Revit Architecture.

You need to set project standards before migrating AutoCAD drawings to Revit Architecture to maintain consistency between the original drawing and the migrated drawing. If you wish to plot AutoCAD drawings from Revit Architecture, you should make all the drawings follow the same standard. If you are using AutoCAD drawings as backgrounds for coordination, you should establish a standard that facilitates best usage of the drawings, such as turning off unnecessary layers and half-toning layers.

Objectives


■ Describe project standards. ■ Describe the style and display settings for a project. ■ Create project standards. ■ Create project templates. ■ Apply view templates. ■ State the recommended practices for working with project and view templates. ■ Export project standards. ■ Migrate project standards.

Lesson: Migrating Project Standards ■ 13

About Project Standards

When you work as a team on a drawing project, each team member can work on a different aspect of the drawing. If there is inconsistency in drawing object styles used by each team member, the drawing becomes difficult to interpret and use. You can prevent these problems and ensure consistency by standardizing the styles and display settings used in the project.

Definition of Project Standards

In Revit Architecture, project standards are a set of styles and display settings that you use to establish, maintain, and synchronize standards across views and drawings in a project. They include family types, line weights, materials, view templates, and object styles.

In AutoCAD, standards define a set of common properties for objects such as layers, text styles, line types, and dimension styles. These standards can be stored in a standards file and used for checking other drawing for compliance.

Standards Drawings

Standards drawings in AutoCAD are the drawings that establish the standards, styles, and display settings that you need to use for the project drawings. You use standard drawings to compare and detect discrepancies in project drawings.

You can create standard drawings in different file formats, such as drawing files (DWG), drawing templates (DWT), and AutoCAD standards drawings (DWS). AutoCAD contains a standards drawings format (DWS) for creating drawings that check other drawings for standards compliance. In Revit Architecture, standards are managed mainly through project templates. Revit Architecture also allows the transfer of project standards from one project to another.

Example of Projects Standards

Styles and Display Settings

When you migrate AutoCAD drawings to Revit Architecture, you can maintain consistency between the original drawings and the migrated drawings by setting project standards for the drawings. To set project standards, you specify various display settings such as line weights and line patterns for the drawings. You also specify styles for standard text, dimensions, and annotations.

Line Weights

You can control line widths for building model elements, annotation elements, and elements in a perspective view by specifying the line weights in the Line Weights dialog box.

The Line Weights dialog box has three tabs that you can use to set the line weights for different elements. The following table describes these tabs.

Import Line Weights

You can control the mapping of layers and line weights imported from AutoCAD with the 16 line weights in Revit Architecture by specifying the settings for import line weights. To specify these settings, you use the Import Line Weights dialog box. The import line weights settings will override any layers or lineweights that are set to default with the specified mapping.

Tab Description

Model Line Weights Specifies the line weights for building model components in orthographic views. You specify line weights for different view scales.

Perspective Line Weights Specifies the line weights for building model components in perspective views. For example, you can set the line weight for a door to a different value in perspective view than it is in orthographic view.

Annotation Line Weights Specifies the line weights for annotation symbols. For example, you can use different line weights to distinguish between section lines and dimension lines.

Sample Chapter



esale


Import Line Weights

The Import Line Weights dialog box contains standard pen and line weight mappings that follow AIA, BS1192, ISO13657, or CP83 standards. You can either use the existing mappings or create your own mappings.

Line Patterns

Line patterns are a series of dashes or dots alternating with blank spaces. You specify the line patterns for a drawing to define the display of lines in a drawing. You can use the predefined line patterns or create new line patterns from the Line Patterns dialog box.

Sample Chapter



esale


The following illustration shows a building model view with different line patterns.

Line Styles

Line styles are a combination of line weight, line color, and line pattern. You use different line styles for different elements. For example, you can use a dashed line for a reference plane.

Revit Architecture provides several predefined line styles. Each predefined line style has a name that describes either the line style, such as Thin Lines, or the location where the program uses the line style, such as Sketch Lines. You create or modify line styles from the Line Styles dialog box.

Sample Chapter



esale


Object Styles

You can set object styles for model, annotation, and imported objects by specifying line weights, line colors, line patterns, and materials for different components or imported geometry layers. You set the object styles in the Object Styles dialog box.

Annotations

You define the appearance of text note leader arrows, loaded tags, dimensions, and annotation symbol styles in a project from the Type Properties dialog box. You can edit existing annotation types or create new types to match the project standards.

Sample Chapter



esale


The following illustration shows a building model created using project standards. The annotation symbol style defined in the project standards specifies the text height and font to be used for room names, room areas, and dimensions.

Creating Project Standards

You create project standards by creating line patterns, line styles, and object styles for AutoCAD drawings that you want to migrate to Revit Architecture. You can then apply the project standards to the imported drawing.

These standards can be saved to a view template and used to standardize any project where the AutoCAD drawing has been imported. The view template can also be used to standardize a Revit Architecture host drawing where project standards have changed during the course of the project.

Applying View Templates

View templates provide default display settings, such as view scale and view range for building model views. You create view templates to specify the project standards for the views in a project. By using view templates, you can standardize the appearance of the views in a project.

You can apply view template settings to an existing view, to a new view, and to multiple views. You can also use an existing view as a view template. For example, for all elevations in a project, you can select the Architectural Elevation template for the Default View Template parameter. Then when you apply the default template to an elevation, the Architectural Elevation template is applied.

View Template Settings

The following table describes various display settings that you can specify in a view template.

Creating a Project Without a Project Template

If you do not want to use any template file, you can select the None option, rather than a template file, and select the initial unit system for the project. Without a template file, only one level, one plan view, and one reflected ceiling plan view are created. Also, only basic wall, curtain wall, and stacked wall components are loaded. Elevations are not created, and windows, doors, and other components are not loaded.

Setting Description

View Scale Defines the view scale of a building model.

Scale Value 1 Defines a custom scale for a view when View Scale is set to Custom.

Visibility Defines the visibility of objects in a building model view.

Model Graphics Style Defines the visual effects applied to a view, such as shading or shading with edges.

Detail Level Defines the detail level settings for a view, such as coarse, medium, or fine.

Discipline Sets the visibility of nonbearing walls and discipline-specific annotation symbols such as framing elevations.

Display Model Controls the display of the model and detailed view-specific elements in a detail view.

Phase Filter Defines the phase properties for a view.

View Range Defines the range in which objects are visible in a plan or RCP view.

Procedure: Applying the Default View Template

The following steps describe how to apply a default view template.

Guidelines for Working with Templates

Follow these guidelines when you create a project template or apply view templates in a project.

Guidelines for Creating Project Templates

■ Templates should include object styles, view settings, and project content appropriate for different types of projects.

■ Do not overload templates with unnecessary content because this will impact performance.■ To transfer project standards from the existing projects to your template file, use File > Transfer

Project Standards. You can also transfer project standards into a project that has already been created.

■ Settings under Options are not part of your project template. These are stored in the registry settings for Revit Architecture.

Guidelines for Applying View Templates

■ Apply the default view templates to the views before exporting or plotting to ensure that all views have the desired view properties.

■ Apply default view templates to a single view or to multiple views simultaneously by specifying a template name for the view’s Default View Template parameter and then applying the view template.

■ If you make changes to a view template, reapply the modified view template to the views that you created using the view template because views and view templates are not linked.

■ View templates apply to imported DWG files, filters, as well as linked Revit files. They do not apply to work sets.

1. Right-click the view window. Click View Properties.

2. In the Element Properties dialog box, under Value:

■ Select the Default View Template row.■ Select a view template to make it the default view template.

3. Click View menu > Apply View Template.

4. In the Select View Template dialog box, select Default View Template.

Exporting Standardized Projects

If you wish to get a standard AutoCAD drawing when you export an Autodesk Revit drawing to AutoCAD, you need to first map the elements to the layers to which they will be exported. Then specify the export range to define whether the complete view or sheet set has to be exported. You can save these sheet sets and reuse them in the project. However, if you want to transfer the view or sheet sets from one project to another, you need to create common view or sheet sets in a customized project template. These sets are then available to all projects that are started with that template.

Procedure: Mapping Elements to Export Layers

The following steps describe how to map elements to export layers.

Procedure: Specifying the Range

The following steps describe how to specify the range to define whether the complete view or sheet set has to be exported.

1. Click File menu > Import/Export Settings > Export Layers DWG/DXF for AutoCAD.

Exercise: Migrate Project Standards

In this exercise, you set project standards and migrate the project standards by exporting Revit Architecture views to AutoCAD. Then you use these project standards in AutoCAD.

You are migrating from AutoCAD to Revit Architecture. You prepare several views in Revit Architecture by setting their view properties so that you can import AutoCAD drawings in these views. Then, you import AutoCAD vector data into these views with different settings. The HVAC layout imported into Revit Architecture is difficult to see because of the ceiling pattern in the imported data, so you turn off the view’s ceiling visibility property. Finally, you export these views with view templates to AutoCAD to ensure that the project standards between Revit Architecture and AutoCAD are consistent.

Lesson: Creating and Managing Drawing

Sheets

Overview

This lesson describes how to create and manage drawing sheets.

A drawing sheet enables you to work on different views simultaneously, and it enables you to plot AutoCAD data from Revit Architecture. By creating sort groups, you can organize drawing sheets in the Project Browser.

Objectives


■ Describe drawing sheets. ■ Describe titleblocks. ■ Create groups for organizing drawing sheets in the Project Browser. ■ State the recommended practices for creating and managing drawing sheets. ■ Create a drawing sheet by using AutoCAD data.

Lesson: Creating and Managing Drawing Sheets ■ 33

About Drawing Sheets

You use drawing sheets to plot views and visualize the building model in multiple views. When you work with drawing sheets, you can edit different views in a single sheet without switching over to individual views. You can also plot AutoCAD data from Revit Architecture by placing it on a drawing sheet as drafting views.

Definition of Drawing Sheets

A drawing sheet is a view to which you can add other building model views and schedules. A drawing sheet in Revit Architecture is similar to a layout tab in AutoCAD.

When you add a view to a drawing sheet, a viewport appears around the view, similar to a border. You can activate a viewport on a sheet to edit the building model directly from the sheet and you can place multiple views on a drawing sheet.

The following illustration shows a drawing sheet that shows a plan view, a section view, and a schedule.

Example of Drawing Sheets

The following illustration shows an example of an AutoCAD drawing linked to a Revit Architecture drawing sheet.

About Titleblocks

When you add a drawing sheet to a project, you can add a titleblock to it. A titleblock enables you to attach information, such as project name, project number, and sheet author, to the drawing sheet. Titleblocks also help manage drawing sheets. For example, you can use the sheet author information to identify the drawing sheets created by a particular author.

Definition of Titleblocks

Titleblocks define the size and appearance of a drawing sheet. They act as templates for drawing sheets. You can either use the predefined titleblocks provided by the software or create a new titleblock by specifying the size of a sheet. Then, you can create labels in a titleblock to display project and sheet information. If you want to use an AutoCAD titleblock in a Revit Architecture drawing sheet, you can import the titleblock geometry to the Revit Architecture titleblock.

Predefined Titleblocks

You can add predefined titleblocks from the Imperial and Metric libraries. In case you do not have the required titleblock, you can also download predefined titleblocks from the Web library.

The following predefined titleblocks are available in the Imperial library.

■ A 8.5 x 11 Vertical■ B 11 x 17 Horizontal■ C 17 x 22 Horizontal■ D 22 x 34 Horizontal■ E 34 x 44 Horizontal■ E1 30 x 42 Horizontal

Sample Chapter

The name of a titleblock describes the paper name, size (in inches), and orientation of the titleblock.

The following predefined titleblocks are available in the Metric library.

■ A0 Metric■ A1 Metric■ A2 Metric■ A3 Metric■ A4 Metric

Example of Titleblocks

The following illustration shows the E1 30 x 42 Horizontal titleblock placed in a drawing sheet.

Managing Drawing Sheets

The Project Browser displays all the views and drawing sheets in a project. If your project contains a large number of views and drawing sheets, you can organize the Project Browser to group the views and sheets, and display only those views and sheets that you need to access. For example, you can set the Project Browser to group drawing sheets by sheet title and then limit the sheets that are displayed in the Project Browser with a filter.

Procedure: Managing Drawing Sheets

The following steps describe how to create a new group for organizing drawing sheets in the Project Browser.

2. In the Browser Organization dialog box:

■ Select the Views or Sheets tab to specify the desired grouping.■ Click New to create a custom grouping.

3. In the Browser Organization Name dialog box, for Name, enter a name for the grouping.

4. In the Browser Organization Properties dialog box, Folders tab, select an option, such as Sheet Name or Sheet Number, from the Group By list.

NOTE: You can group views or sheets by any view property. For example, you can group by discipline or by the desired number of leading characters of a sheet name.

5. Change any other secondary grouping settings and select a Sort By attribute.

Guidelines for Creating and Managing Sheets

You can leverage AutoCAD data in your Revit Architecture project by using the AutoCAD components in the Revit Architecture drawing. To best utilize the AutoCAD components, follow these guidelines.

■ Leverage AutoCAD backgrounds to create sheet titleblocks. You can import an AutoCAD titleblock into the Revit Family Editor and use this as the background for your Revit titleblock.

■ Use labels as dynamic fields in your titleblock so that they can read and display project data from your project when loaded.

■ When organizing your Project Browser views, it is convenient to use the Not on Sheets parameter to distinguish between the views that have been placed on sheets and those that have not been placed.

■ In Revit Architecture 2008, you can pan views that have been added to a sheet without modifying the crop region. You can also rotate a viewport on a sheet.

■ In Revit Architecture 2008, you can use dependent views and match lines to place large floor plates on multiple sheets. You can also use dependent views to place multiple copies of the same view on different sheets.

Exercise: Create Drawing Sheets Using AutoCAD Data

In this exercise, you create a drawing sheet by using AutoCAD data and add a custom titleblock to the sheet.

When you are ready to document and plot your project, you create custom titleblocks with a company logo and other company and project specific attributes. You can leverage the existing AutoCAD titleblocks to speed up the process. You add labels to the titleblock to make the attributes dynamic. These labels read and display project information automatically when loaded into your project.

In your building model design, you need to create a new drawing sheet with a custom titleblock. You also need to add a drafting view that contains imported AutoCAD data in the drawing sheet.


■ Import an AutoCAD titleblock.■ Customize the titleblock.■ Create a drawing sheet.■ Add a view to the drawing sheet.

Import an AutoCAD Titleblock



To complete the exercise, follow the steps in this book or in the onscreen exercise. In the onscreen list of chapters and exercises, click Chapter 1: Starting a Revit Architecture Project. Click Exercise: Create Drawing Sheets Using AutoCAD Data.

1. On the File menu, click New > Titleblock.

2. In the New dialog box:

■ Browse to Imperial (Metric) Templates\Titleblocks folder.

■ For File Name, select E1 - 42 x 30.rft (A0 metric.rft).

■ Click Open.

Customize the Titleblock3. On the File menu, click Import/Link > CAD Formats.


■ Browse to the folder where you installed the courseware datasets.

■ For File Name, select i_title block e1.dwg (m_title block a0.dwg).

■ Under Import or Link, verify that Link (Instead of Import) check box is clear.

■ Under Positioning, verify that Automatically Place and Center-to-Center are selected.

5. In the Import/Link dialog box, click Open. If you get an error message that asks you to import valid elements from the Model space, click Yes. The AutoCAD titleblock is imported as an import symbol.


■ Move your cursor over the inner edges of the titleblock import symbol till the import symbol highlights.

■ Click to select the import symbol.

7. On the Options Bar, click Partial Explode. This explodes the geometry in the AutoCAD import, allowing blocks and text blocks to be edited individually. This is preferred to fully exploding AutoCAD imports because doing the latter explodes the geometry to linework. In complex drawings, this can be difficult to manage and the sheer number of line objects in Revit Architecture can cause performance degradation.


■ Zoom in the titleblock.■ Select the Project Name label.

■ Press DELETE to erase the text.

2. On the Design Bar, Family tab, click Label.
