  • 1. UNIVERSITY AT BUFFALO Project 03 Solid Modeling Assignment 03 Ryan R. Bierl 10/1/2009 Project 03 was an introduction to more advanced tools in Pro Engineer. These tools include sweep, blend, and warp. Also Project 03 consisted of modeling a cell phone and creating an assembly drawing with a Bill of Materials. These new skills will aid in the modeling of parts in the future.

  • 3. 1 Introduction Project 03 is an introduction to the advanced modeling techniques available in Pro Engineer. These techniques include, sweep, blend and warp. Also in Project 03 we will be modeling a consumer product; the cell phone. 2 Project Requirements Project 03 required us to follow the Pro Engineer Wildfire 4.0 Tutorial, the “Tooth Paste Tutorial”, and “Getting Started with Pro Engineer Wildfire 3.0” to complete the parts. We had to create a part that included the sweep feature, a part that included the blend feature and a part that included the warp feature. Also we had to model the parts of a cell phone and create an assembly drawing along with a 2D drawing with a Bill of Materials. 3 Results 3.1 Part A (a) (b) Figure 1 (a) The CAD model of the block in Part A; and (b) the same CAD model of Part A at a different view. Part A consisted of modeling a part that included the sweep feature. This part was relatively easy to complete and the Tutorial was very helpful. To complete the sweep you first must draw a path for the feature to follow. After this is done all you need to do is draw the correct cross section and you are finished. 3
  • 4. 3.2 Part B (a) (b) Figure 2 (a) The CAD model of the blend in Part B; and (b) the same CAD model of Part B at a different view. Part B consisted of modeling a part that used the blend feature. This feature is a little more complicated than the sweep but is just as useful. First you must create varying datum planes to create your sketches that will provide the guidelines for the blend. After this is done you dictate what direction you want the blend to follow and then you are finished. The Tutorial was very helpful in guiding us through this section of the project. 3.3 Part C (a) (b) Figure 3 (a) The CAD model of the warp in Part C; and (b) the same CAD model of Part C at a different view. Part C consisted of modeling a tube of tooth paste that seemed to have already been used. To accomplish this we were required to use the warp feature in Pro Engineer. Doing this was relatively easy when following the “Tooth Paste Tutorial” on UB Learns. The warp feature was easy to use but difficult to recreate exactly what was in the example. Also the blend used in this model was much easier than in Part B. 4
  • 5. 3.4 Part D (a) (b) Figure 4 (a) The CAD model of the cell phone in Part D; and (b) the same CAD model of Part D at an exploded view. Part D consisted of the modeling of a cell phone. This was by far the most time consuming and challenging of all the parts of Project 03. Most of the parts of the cell phone required many advanced techniques to be used and it was very difficult to get everything just right. Also the assembly part of modeling the cell phone proved to be quite the challenge. It was very difficult to get the constraints to act the way you needed them too. Sometimes you just had to repeat the steps over and over to finally get them to work right. This was annoying. Also the tutorial for this section was very wordy and probably could have been a lot shorter and more to the point. (a) Figure 5 (a) The 2D drawing of the exploded cell phone with Bill of Materials 5
  • 6. 4 Discussion Project 03 was actually quite difficult to accomplish. We ran into many problems while modeling the various parts. Many of the steps indicated by the tutorials on UB Learns were difficult to do on the new version of Pro Engineer. Some of the steps told us to click certain buttons or refer to certain tabs that we were not able to locate on 4.0. Also, one specific problem we ran into was creating the holes on the covers of the cell phone. We were instructed to locate the holes based on the axis of the protrusions. After that we were supposed to select a certain surface for a secondary reference; however the secondary reference was not an option. We checked many times and were unable to rectify the situation. We were forced to reference the holes a different way to complete the part. There were most likely more problems that we faced since it took us almost 20 hours to complete. 5 Conclusion The goals of this project were obviously to enhance our understanding of Pro Engineer and increase our skill level. This was definitely accomplished through blood, sweat and tears. I have learned many new features such as blend, sweep and warp. These new skills will help me model more advanced parts in the future. I believe I have completed these parts successfully and accurately. 6 References The following materials were used to complete Project 03:  Pro Engineer Wildfire 4.0 Tutorial and Multimedia CD written by: Roger Toogood, PH.D., P.
