Creating a 3D part is a simple straight forward process. The only hard part of making the first 3D part is all the different file types. When Autodesk inventor is opened and you select to make a new file you are presented with a nice little window, looks simple enough? Look again there's a nice list of various different file types with different formats. Unless you know what your looking for it can be a pain trying to find the right file type. I still get it wrong, so I opted to write a small text file telling me which are the commonly used files to create a single part, and assembly and a technical drawing. I mean who would have thought that BSI.IDW is a drawing! I rarely remember which one is right.
In this instance Pro Engineer is much simpler, within the Pro/E window there are 3 simple buttons, the first being called "Default Starter Part", next "Default Starter Assembly" and the last being "Starter Drawing for Models". After this a few windows pop up, one asking for a name for the part/assembly/drawing. After this we get a second window which is usually ignored and the default responses are accepted, relatively straight forward. So for ease of creating a new part I would have to give this point to Pro Engineer.
Lets focus on creating a single part for a little bit. When Pro Engineer loads up it shows you a set of three planes, being the horizontal vertical and the end plane. To start making the part you need to select what you will want to do with the sketch you are yet to create. For example if you want to make a simple bar, typically you would go with drawing a circle and then extruding it up the length of the bar. In Pro Engineer you need to select extrude as the first thing. From here a little toolbar appears at the top of the window with "Placement" highlighted in red. When you click on placement you then have to click on define..... and then the plane...... and then sketch.....and then finally you can start drawing! To me this seems a few to many clicks to simple say "I want to sketch on this surface and extrude it". This process then changes for all sketches that you want to do that are directly on a surface of the part. To do a sketch on a surface you must first select the surface and then select what you want to do with the sketch and so on like before. For sketching on a plane you use the same process as the first sketch.
In Autodesk Inventor we have a slightly different set up, first when you open a new part it automatically goes straight into the sketch mode, but after this for any other sketches you follow what feels like a much more logical path to me. You select "Create 2D Sketch" from here you then select the surface on the part you want to sketch on.
