The document provides instructions for part modeling in Pro/ENGINEER. It discusses the mirror tool, relations, and basics of part modeling. It demonstrates how to sketch a shape, apply relations to its sides, and access the relations dialog box. It also shows how to set up drawing units, select the front datum plane for sketching, extrude a rectangle, add a hole using the hole tool, and change the extrusion direction. The goal is to get ready to model a robot with different parts like a base, walls, shafts, wheels, top, motors and batteries.

- 1. Week 2 Day 2 Workshop by
- 2. Highlights of Previous Lecture • Sketching Tools – Line, Circle, Rectangle, Arcs, Fillet • Dimensions – Definition, Weak & Strong Dimensions • Constraints – Definition, Types of Constraints
- 3. Today’s Lecture • Mirror Tool • Relations – Definition – Types of Relations – How to Use • Basics of Part Modeling – Part Modeling in Pro/ENGINEER • Practicing Part Modeling
- 4. Mirror Tool • Draw a circle of 4 unit diameter • Select the center line tool from the line tool • Draw either a vertical or horizontal line • A 2-point line will be drawn of infinite length • Select the circle and the mirror tool • Now select the center line – It will be prompted to do so in the message pane • The circle will be mirrored
- 6. Relations • Definition – user-defined equations written between symbolic dimensions and parameters – allowing users to control the effects of modifications
- 7. How to Use Relations • Draw a kite shape • We will now apply relations to its sides • Access “Relations” through “Tools > Relations”
- 12. PART MODELING
- 13. Part Modeling • Also called Solid Modeling • Click “New” and then select “Part”
- 14. Setting up Drawing Units • Edit > Setup • Menu Manager > Units
- 15. Units Manager
- 17. • These 3 drawing planes are called DATUM planes – Datum means a point, line, or surface used as a reference • Datum planes are used as sketching surfaces
- 18. • Select the FRONT datum plane – It will turn red – Then click the Extrude button located at the bottom left or above right of the screen – Click the Define button
- 20. • Sketch a rectangle of 40x25 cm
- 21. • Click the small blue color check present at the bottom right of the screen.
- 23. • Type the extrusion depth you want • Click the green check button to extrude
- 24. • Your drawing now becomes a solid model
- 25. Viewing your Drawing • The Saved view list option, present in the Views toolbar gives you different options to look at your drawing from various perspectives
- 26. Adding a Hole • Select the FRONT view • Select Extrude 1 in the Model Tree located on the left of the screen
- 27. • Click the Extrude tool • Placement > Define > Sketch • Draw a circle at the center of the rectangle of 8cm diameter
- 28. • Next click the blue check button • Your drawing will now look similar to this
- 29. • Click the Remove Material button • Click the Standard Orientation view option
- 30. Extrusion direction Extrusion depth
- 31. • Click the Extrude Direction button to change the direction of Extrusion
- 32. • Click the GREEN check button
- 33. Viewing the Image Taken from Pro/Engineer Wildfire Instructor by David S. Kelley, pg. # 27
- 34. The Hole Tool • Another way to make a hole • Select the extruded surface as shown
- 35. • Hole Tool > Placement > Define > Sketch
- 36. Simple Hole Standard Hole Hole Hole Diameter Depth
- 37. Hole diameter Edge Reference Handle Hole depth
- 38. • Select the Through All option
- 40. • Drag the green handles to their edges – Type “2.00” in place of 2.47 & “4.00” in place of 3.82
- 41. • Click the green check button
- 42. • Use the MMB to rotate the solid model
- 43. Getting Ready to Model the Robot • What we need – Base – Side Walls – Shafts – Wheels – Top – Motors – Batteries
