Pro/ENGINEER Tutorial Lesson #8: Creating an Engineering Drawing
Oops! Wrong Lesson - return to main tutorial page.

Overview of this Lesson
The primary form of design documentation is the engineering drawing. The drawing must contain complete and unambiguousinformation about the part geometry and size. Over the years, the layout and practices used in engineering drawings have become standardized. This makes it easier to read the drawing, once you know what the standards are. Fortunately, Pro/E makes creating drawings relatively easy. First of all, it is virtually impossible for Pro/E to create a part that is not physically realizable - we don't haveto worry about any 3-pronged blivots (see the introduction to this series). The Pro/E solid model contains all necessary and sufficient information in order to define the part geometry. Therefore, by getting all this information into the drawing, it is very difficult to create a drawing with insufficient information. Secondly, when Pro/E is used to create a drawing, you will find that all thestandard practices are basically built-in - if you accept the default action for commands, by and large the drawing will be satisfactory. There are a number of commands we will see that will improve the "cosmetics" of the drawing. In this lesson, we are going to create drawings of two parts: an L-bracket support and a pulley. We will first create these parts and then produce the drawings. At the end,we will create hard copy of each of the drawings. Both parts will be used in a subsequent lesson on creating assemblies, so don't forget to save the part files. We will also discover the power of bidirectional associativety, mentioned in the tutorial series introduction. Here are links to and brief descriptions of the two sections of this lesson: 1. The L-Bracket Creating the part Creating thedrawing 1. selecting the sheet 2. creating the views 3. adding dimensions 4. cosmetic changes Changing the part/drawing Sending the drawing to the printer 2. The Pulley Creating the part Creating the drawing 1. selecting the sheet 2. creating a section view 3. adding dimensions 4. cosmetic changes

Section 1: The L-Bracket
Creating the Part
Create the part shown in the figure below using the partname lbrack. Study this figure carefully. Note that the units are in millimeters. When you have created the part, but before you create any features, select (from the PART menu) Set Up > Units > Length > Millimeter > Done Make sure that the back surface of the vertical leg is aligned with DTM3, the lower surface of the horizontal leg is aligned with DTM2, and the axis of symmetry is DTM1.

Figure 1 In Pro/E, the part should look like this:

Figure 2 Don't forget to save the part! We are now ready to create the drawing.

Creating the Drawing of the L-Bracket
1. Create the Drawing Sheet Select the following: Mode >Drawing > Create > [lbrack] A new window will open up with the title Drawing:LBRACK. Note that the part window will stay open. You can resize the drawing window by dragging on its border. You can tell which window is open by the series of stars on each end of the title. Select a drawing mode and size: Set Dwg Size > Landscape > A An A-sized sheet is 8-1/2" by 11".

2. Adding Views Now we have to tell Pro/E what to create the drawing of. In the DRAWING menu, select Views. Since no model is yet defined for this drawing, you will be prompted to enter a model name. If the lbrack.prt is currently in the Pro/E session, this will be...
