Welcome to my first solid modeling assignment using Pro/E. This assignment allowed me to become familiar with many of the uses Pro/E has, along with using many of its commands.  On this page you will find pictures of my finished models, along with a brief descrption of each model. Attached to this page, you will find all of my CAD files, as well as eDrawings for each part. You will also find my written report available in a pdf format. Thank you for visiting and I hope you enjoy!
The above figures are the final product of the first part of this assignment. This was a basic introduction to Pro/E. This model allowed me to familiarize myself with some of Pro/E's tools while not having to create a complex part. I was able to learn how to extrude a sketch, both to create a 3-D model as well as to remove material, such as the middle of this model.  I also learned how to quickly create holes through the entire object using the "hole" tool.  I also got practice rounding and chamfering the edges of this object. This was a very good introduction to a very useful CAD program.  
The above figures are the models that I created in the second part of this assignment. This model was much trickier to create than the first model.  It required us to create a revolved part, which is the part on top of the base in the above figures. It also required us to use the "Mirror" tool not only with cut, but also with the holes in the object.  Using the mirror tool is a great way to save time. If you have many of the same parts to a model, instead of recreating them over and over again, this tool allows you to quickly recreate them. 
These figures show the final part of this assignment, the turbine. This part looks a lot more complicated than the first two parts, but using Pro/E and its many tools, it can be easily created. I once again had to use the "Revolve" tool to create the base of this object. Once I had one blade sketched and extruded, I had to create the cut. This can easily be done by first sketching it on the blade, then using the "Extrude" tool and removing the material, much like the cuts in the first two models. To make sure that it would cut through all the blades once they were created, I had to revolve this cut. Then finally I used the "Pattern" tool to make the remainder of the blades. 
Below is the written report that i compiled for this project:

2         Introduction

The purpose of this project was to get us acquainted with using Pro/Engineer and many of its features.  We create three different solid models, each of which requires us to use different tools in Pro/E. 

3         Problem definition / Problem statement

The purpose of this assignment was to familiarize us with Pro/E and some of its many tools.

4         Result

This section of the report will go through how each model was created, as well as showing you a finished product of each model.

4.1       Creating a Simple Object

The first model that we had to create for this assignment was just a simple object.  Since this was our first experience with Pro/E, this model was very simple, and required only a few steps to complete.  The first Step that we had to complete was to use the Sketcher to create a sketch of the outline of the object.  Once we had this part sketched, we had to exit out of the Sketcher and use a tool called the Extrude tool to create the 3-D model of the our sketch. 

Once we had this 3-D block with a rounded top, we had to create the cut in the center of it.  We did this by creating another sketch on the long side of the model.  Once we had the sketch of the cut we wanted to perform, we once again exited the Sketcher.  To create this cut, we once again need to use the Extrude tool, only this time for a different purpose.  Once we have the sketch selected, and are in the Extrude tool, we have to make sure to select the reverse direction of the extrude, and also the remove material button.  This allows us to create the cut that you see in the above figures. 

Once we have the correct cut, we next have to create the holes in the object.  While it is possible to create these using the extrude tool in the manner that we previously used it for, Pro/E has a tool that makes this step very easy.  This tool is called the Create Holes tool.  Once you have this tool selected, you need to select the plane on which you would like to place the holes.  Once you have this selected, you can then specify the holes diameter, and its distances from the edges to get its precise placement.  Once we have assigned these constraints, we must then select the option that will allow us to create a hole through both sides of this object.  This is located in the holes menu while the tool is selected. 

The final step for this object is a simple one.  We must create rounded and chamfered edges.  To do this, we must select the edges that we want to do this to, the select which of tools we want to use.  Once we have selected this, we can then specify the constraints for these edges that we want to create.  And once we attach our name using the alphabet tool in the Sketcher and extruding it, we are finished with this part.

4.2       Revolved Protrusion Part

This part was more complicated than the first part to create.  It required us to learn how to use a few new tools that Pro/E has to offer.  The first thing we must do, as always, is create a sketch of our part.  To do this, we must once again use the Sketcher.  Once we have the base piece sketched and dimensioned properly, we can exit the sketcher and extrude it.  Once this is done we can begin on the top piece. 

Since we want to create a sketch and then revolve it, it is convenient to select the Revolve tool before creating the sketch.  Once you have done this, and made your specifications for the revolve, you can once again enter the Sketcher to create the sketch of the top part.  Once you have done this and properly dimensioned the part, you can exit the sketcher and revolve your part. 

The next part is creating and mirroring the cut in the base part.  This requires you to create another sketch on the base part, and the extruding it inwards, using the remove material button.  Once you have done this, select the mirror tool to mirror the cut.  Once this is done, we will once again use the Hole tool to create the holes in our object.  We only need to do this once, as we can mirror these holes in a similar fashion that we mirrored our cut.  Once this is complete, we can round and chamfer our edges in the same way as we did in the first part.  The finished product looks like figures 2a and 2b.

4.3       The Turbine

This part also requires us to use new methods in Pro/E, in order to create another more complicated part.  But, as usual, we must first start by creating a sketch.  Since we want to revolve this sketch, we again must select that tool before using the Sketcher.  Once we have done this and are in the Sketcher, we can create the sketch of our first part.  Once this is done, we can exit the Sketcher and revolve the part.   To create the blade, we must again create a sketch o it first, and then extrude it.

 Once we have the blade extruded, we want to make a sketch of the cut we want to perform.  So we go back into the Sketcher and create this sketch on the blade.  Once we have this done, we exit the sketcher, extrude it being careful not to forget to click the remove material button, and then revolve it.  Once we have done this, we can create the remaining blades by selecting the Pattern tool and incrementing the blades for one every 30°.  Once this is complete, you have a finished product that looks like figures 3a and 3b. 


5         Discussion

Since this was my first experience with Pro/E, I had to repeat many of these steps to obtain the model that I wanted.  Once I got a basic understanding of how the program works, and how to best use it, I had relatively little trouble creating these parts. 

6         Conclusion

Pro/E is a very useful CAD program.  It has many useful tools, and is very user friendly.  Once you have a basic understanding for the procedures that are needed in order to best use the program, it is quite simple to create models such as these.
