A completed Engineering Drawing A engineering drawing consists of the drawings for all the parts

and a final assembly. For example, if we have three parts to form a final assembly, then the completed engineering drawing will consist of three sheets for parts and one for assembly. There are totally four sheets in the engineering drawing.

The files need to generate an engineering drawing: All the part files: *.prt One assembly file: *.asm One or more frame files: *.frm

Annotate 1

How to show dimensions automatically on a drawing:

Annotate -> Show Model Annotations -> Select views, components, and/or features for which you want to show annotations -> V -> check on show -> Apply

How to delete dimensions on a drawing: Select the dimensions you want to delete ->

Delete

Annotate 2

How to show dimensions on a drawing by hand: Display a dimension between two points: Annotate -> |<->| -> select one point and the other -> move the cursor to the location you want to place the

dimension and press down the middle mouse key Display a diameter for a circle: Annotate -> |<->| -> double click on the circle, move the cursor to the

location you want to place the dimension and press down the middle mouse key

Annotate 3

How to show dimensions on a drawing by hand:

Display a dimension between two circle centers: Annotate -> |<->| -> click on one circle and the

other -> Center -> Horizontal/Vertical -> OK Display a radius for a circle: Annotate -> |<->| -> click once on the circle, move the cursor to the

location you want to place the dimension and press down the middle mouse key

Annotate 4

How to insert a jog: Select a witness line by click on it -> press down

the right mouse key -> Insert Jog -> Pick point on the witness line for the jog -> Select the position for the jog using mouse drag

How to remove a dimension: Click on the dimension you want to remove ->

press down Del key on keyboard

Annotate 5

How to change arrow style: File -> Drawing Options ->These options control leaders -> Option: draw_arrow_style; Value: filled, closed & open

How to change font: File -> Drawing Options -> Active Drawing -> drawing_text_height -> Option: draw_text_height; Value: 0.08

Annotate 6

How to show a text symbol: Select the dimension you want to add text symbol ->

Press down the right mouse key -> Properties -> Display -> move the cursor before @D -> Text Symbol -> select

special symbol

Annotate 7

Commonly-used values for the necessary parameters in a standard engineering drawing:

drawing_text_height: 3.5 (Active Drawing) text_width_factor: 0.6 (Active Drawing) projection_type: first_angle (These options control view and

their annotations) drawing_arrow_length: 3.5 (These options control leaders) drawing_arrow_style: filled (These options control leaders) drawing_arrow_width: 1.0 (These options control leaders) drawing_arrow_style: filled (These options control leaders) File -> Drawing Options -> change parameters ->

Add/Change

Multi-Sheet Drawing 1

Add a new drawing sheet: Layout -> New Sheet Check the page number and total number of pages

Add a new model in the new drawing sheet: Layout -> Drawing Models or File -> Drawing

Models -> Add Model -> select new model with preview option ->

Open -> Done

Multi-Sheet Drawing 2

Create all the views: General -> FRONT VIEW -> SIDE VIEW -> PLAN VIEW -> GENERAL VIEW

How to change scale: Double click on the “view” -> Scale -> Custom

scale -> enter the proper scale you want -> Apply -> Close

Multi-Sheet Drawing 3

Add an assembly file (*.asm): Layout -> New Sheet -> Drawing Models or File -> Drawing Models -> Add Models -> select an *.asm file -> Open -> No combined state (without exploded)/ Default (with default exploded)

You may need to explode the assembly by hand as

we discussed in a previous class.
