Tutorial 1: Pro/E Wildfire 5.0 Modeling andDrawing

Dept. of Mechanical Engineering 22.321 Mechanical Design IWritten By: Chris Morand and Xiang Li

Revised by: Nick Cleveland 9.6.2011

Objectives:

This tutorial is an example of the basic techniques used to create a Pro/E part and drawingfile. You can use the techniques in this tutorial to create the links and base plate needed tocomplete the design of a linkage.

After completing this tutorial, you will be able to: Complete basic solid modeling. Create reference and sketch

Create engineering drawings Insert new views Add and modify dimensions Add notes into drawing

The first step in creating any Pro/E document is creating a working directory in which allfiles will be saved to and opened from. This is especially important when creatingassemblies or mechanisms since all files related to the assembly or mechanism must becontained in the same folder. Setting up a folder for each project should be the first thingyou do.

To set up a working directory first create a folder on the hard drive or on a removablestorage device to act as a working directory. Then:

Open Pro/E Wild Fire Start All Programs Pro Engineer Pro Engineer

Click OK if any errors pop up to continue.

Select File set working directory Select the previously created folderOK

Once there is a proper working directory you are ready to begin creating parts, assemblies,and mechanisms. Remember to save your work throughout the process. To save a file click

the Save button and click OK to save it in your specified working directory, or use File->Save.

In this tutorial you will make a single link that has a pin on one side and a pin hole on theother. Remember that the pins and pin holes must be the same diameter if they are to beassembled and the pin lengths must be well thought out so that you dont get interference.To create the link:

4. Click on the FRONT datum plane (this will allow you to sketch on that plane andextrude in the direction of the arrow)

5. Click Sketch on the Sketch dialog box.

6. Using the circle tool (found in the right hand tool box) create two circles withthe same radius (the 2 circles are the exact same size when the notation R 1 appearsnext to both circles) with the center of one circle on the cross of the reference axes asshown in Figure 2. The exact dimensions will be altered later in the tutorial (justdraw arbitrary sizes).Use the middle mouse button to stop drawing circles and returnto the normal mouse pointer.

7. Using the line tool (found in the right hand tool box) draw two tangent lines betweenthe circles as shown in Figure 3. (The cursor should snap to the top andbottom of each circle and there will be a T notated next to the point on either circlewhen the line is tangent to that circle). Click the middle mouse button once to stop

drawing the first line, then draw the second line. Click the middle mouse button onceto stop drawing the second line and a second time to stop using the line tool.

4. Click Open and OK.5. Click the General button icon which is on the layout tab.

6. In the message window right below the tool bar it will sayClick a position near the middle of the page.

7. The Drawing View dialog box will appear. Under View Type select Front and clickApply and Close. A front view of your part should appear.

8. Click on the front view and then Right click and hold on the front view and selectthe option Insert Projection View. Do this twice to place one view below thedrawing of the front view and one to the right of the front view.

9. To move your views, right click on a view and uncheck lock view movement.

Now that you have the three views of the drawing it is time to put dimensions on thedrawing. To add dimensions:

1. Click on the annotate tab.2. Select Show Model Annotations.

You can also right click on a view to bring up the Show Model Annotations.

3. Select the dimensions you wish to apply to each view so that all dimensions are definedbut not defined two or more times, and also so the drawing is easily readable.

4. You can change the number of decimal places in dimensions by clicking decimal places.. inthe annotate tab. Select the dimension, enter the number you want and click the green check.

Your drawing must now be formatted so that all important information is readily available.Important Note! Format Your Drawing According to the Example. When completed itshould look exactly like the example except for the dimensions of the links which are

specific to your linkage.

1. You can zoom in on the views of the drawing by using the zoom toolsin the top toolbar and clicking the middle mouse button to get back to

the pointer.2. You can drag the dimensions around so that they can all be seen by clicking on them

and then clicking a second time and dragging.3. The arrows can be flipped by right clicking and holding on the dimension then

selecting flip arrows.

4. To switch to a wire view of your links first click on the front view of your link to

select it. Now click on the wire frame button on the top toolbar. Click anywhereon page to deselect your view (Note if your link view disappear dont worry just

click the repaint button in the top toolbar to redraw the view.)

5. Make sure the plane, axis, point and csys display buttons are turnedoff so they dont clutter your drawing. (Note if these displays dont disappear click

the repaint button in the top toolbar to redraw the view. These displays arebrown writing on the views.)

6. The critical dimensions on the links are the length between the hole and the pin andthe hole and pin diameters as well as pin height. Therefore these dimensions shouldbe precise to 3 decimal places. To change the number of decimal places displayedclick on the dimension (should turn red from yellow). Then right click on thedimension after it is selected and click on properties. In the properties box changethe number of decimal places to 3 in the format section. Then click OK. Likewisethe thickness of the link and the radius of the ends of the links should only be precise

to 2 decimal places.7. Text can be added to the text blocks at the bottom of the page by clicking the Create

note button in the top tool bar. Click Make Note at the bottom of the MenuManager and selecting a location for the note. Text is entered in the messagewindow at the top left of the screen. Pressing enter after each line of text andpressing enter twice after the last line of text. Different text patterns with andwithout leaders can be done by using the options given in the Menu Manager afterclicking the make note button. Your drawing should look similar to Figure 12 with acorrect title block (the link dimensions will differ). Once a note is created you canmove it around so it is in the correct box. Also if the text was entered wrong or if itneeds to be resized the text can be formatted by clicking on a note to select it and

then right clicking the note and selecting properties. You only need to fill in yourname, scale, the date, the sheet, revision, material and the title of your part blocks.

8. Important note. The drawings can be saved as a PDF file by clicking the save as PDFbutton in the top tool bar (located next to the usual save button). When using thismethod the drawing will be black writing on a white field as in Figure 12. DO NOTTAKE A DIRECT SCREEN SHOT OF PRO/E FOR A REPORT. Once the drawingis a PDF open the PDF drawing and save the PDF as a JPG file. The JPG file iseasily inserted into Microsoft Word as a normal image is.
