Lesson 2: Correcting Reference Paths

Introduction

In Infraworks 360, when multiple users are collaborating on a shared model using disparate PCs, it’s

important to ensure the reference paths for the various data sources are appropriate for the end user.

When preparing the lab, we tried to make the paths on the lab machines identical to those in our local

system; however, it is possible that the files are not in the correct location. In this lesson, we will open an

existing Infraworks 360 model, use the manage tools to review the model and make corrections, if

necessary to the file paths.

Lesson 3: Creating a New Infraworks 360 Model

Introduction

Infraworks 360 allows you to rapidly build and configure 2D and 3D raster and vector models for realistic

visualization of utility assets. In this lesson, we’ll create a new model, configure it for a small area of

downtown Alexandria, LA, and add a number of data sources.

Key Concepts


Model

Data Source

Terrain

Surface

Pipelines

Roads

Water Area

Objectives


Create a new Infraworks 360 model.

Add, configure and import data sources to the model.

Navigate through the model.


22

Exercise 1: Create a New Model

In this exercise, you create a model from scratch using provided data sources. To start with, you must

create an empty model.


Use the Infraworks 360 home screen to create a model.

Add terrain imagery.

Add surface data.

Start Infraworks 360 for this exercise.

1.

On the Infraworks home screen, click the New button.

2. The New Model dialog appears. In the lab, you will use the location C:\datasets\hands-on labs\UT6014-L Infraworks as BIM for Utilities\UT6014-L\cityofalexfiles. Use the folder option, circled in red to the right, to choose this folder. Use the model name alexau7 for your new model to preserve the existing model prepared for the class.


23

3.

Select the Define Model Extents check box. This is important to minimize the amount of data for this lesson. Load extent information from one of the existing DEM files. Use the Load Extent from File button. The file selection dialog will be displayed. Navigate to C:\datasets\hands-on labs\UT6014-L Infraworks as BIM for Utilities\UT6014-L\cityofalexfiles

and in the subdirectory Alexandria_LiDAR\Classified_LAS_AU

In that directory, select one of the two TIFF images. Press Open.

4. In the New Model dialog, press the OK button

A new model is displayed in Infraworks 360 and the Data Sources tool is automatically loaded to help you

start adding data.


24

5. Use the Add file data source button to add a raster (surface). Click Raster

6. Navigate to

C:\datasets\hands-on labs\UT6014-L Infraworks as BIM for Utilities\UT6014-L\cityofalexfiles

and in the subdirectory Alexandria_LiDAR\Classified_LAS_AU

Select the file downtown4x4 ba

This is a bare earth file generated previously.

Press Open. In the data sources tool, the raster file appears as described to the right. Note that the file comes in as Configured. This is because surface raster data sources are easily categorized. Other imagery, vector data sources and 3D models must be configured.

7. Click on the Add file data source button again and add a image file.


25

8. Navigate to C:\datasets\hands-on labs\UT6014-L Infraworks as BIM for Utilities\UT6014-L\cityofalexfiles

Select the file Alexandria New.sid


Press Open. In the data sources tool, the raster file appears as described to the right. Note that the .SID file comes in Not Configured. This is because this image lacks embedded coordinate system information. To view the name and category of the data sources, expand the Name column by grabbing the sash between the Name and Source Type column headings.

9. Configure the imagery by right-clicking on the data source and clicking Configure.

10 The Data Source Configuration dialog

is displayed. In this dialog, set the coordinate system to LA83-NF by directly typing in the Coordinate System field.

11 For all data sources (vector and

raster), it is very useful to check the Clip to model extent check box to ensure that data outside the extents of your project is neither imported nor visualized. Failing to check this will result in all data being imported. Nothing will be visualized beyond the project extents; but the extra data can have a negative effect on performance.

12 Press the Close & Refresh button.


26

After a few moments, the Infraworks 360 screen refreshes with the configured data.

Exercise 1 Review

In this exercise we created a new Infraworks 360 model and configured raster data sources.


27

Exercise 2: Configure Vector Data Sources

In this exercise, you will add vector data sources to your model.


Use the Data Sources panel to add and configure a variety of vector data sources.

1.

Use the data sources button to add a SHP data source.

2. Navigate to

C:\datasets\hands-on labs\UT6014-L Infraworks as BIM for Utilities\UT6014-L\cityofalexfiles\TL_2011_22079_AREAWATER

Select the file downtown4x4 ba

Press Open. In the data sources tool, the vector files appear.


29

9. Double-Click on the EL_CONDUCTOR vector file to display the Configure Data Source dialog. For Type choose Pipelines. This is important because Infraworks treats all linear service delivery lines as Pipelines. Configure the elevation offset of the conductors by pressing typing 25 in the text box and changing the units to feet. Note that elevation offset from affects only the starting vertex of the conductor. Similarly, the elevation offset to affects only the terminating vertex. Configure the conductor thickness using the Size panel Use something that is large enough to show the conductor but small enough to appear realistic. Make sure to use appropriate units. Press Close & Refresh.

10 The Data Source Configuration dialog is displayed. In this dialog, set the coordinate system to LA83-NF by directly typing in the Coordinate System field.

11 Press the Close & Refresh button.


30

9. Double-Click on the EL_POLE vector file to display the Configure Data Source dialog. For Type choose Pipeline Connectors. This is important because Infraworks 360 treats all connected point features in a utility network as Pipeline Connectors. Use the Style Chooser to select how you want the pole to look. Use the Style Chooser to navigate to 3D Models/Energy and choose Distribution Pole. Choose a Height of 35 ft. Be careful with units. Press Close & Refresh.
