Project 03 introduced students to more advanced modeling tools in Pro Engineer like sweep, blend, and warp. Students used these tools to model parts and a cell phone. Modeling the cell phone parts and assembly was challenging and time consuming. The tutorials were sometimes difficult to follow due to differences between the tutorial version of Pro Engineer and the students' version. Overall, the project helped students improve their modeling skills for future projects.

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.

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.

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.

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.

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.
