CAD Update

Over the last few days, drive line components have begun to arrive, and we have started the cataloging process by scanning them, then using RapidForm to transfer them into parts that can be recognized in SolidWorks. The first of these parts was the engine mount as seen below.

What we've found from the training sessions and from practicing on other components is that the best method is to disassemble parts to the lowest level and scan each part individually, then put the models back together in the SolidWorks environment as an assembly of multiple components just as they are in physical form. In the case of the engine mount this is pretty easy since there are two parts to it: the mount and the heat shield.

Because the mount has some complex geometry, I scanned that in to be sure that I captured the detail, but since the heat shield is a simple part that's easily modeled by extruding circles and apply some radii to the edges, I reverse engineered that right in SolidWorks. This hybrid approach is a method that will be commonly employed during the development process. As we continue to model parts I will be sure to post the results, especially for some of the more interesting and complex components.

You said that you reverse engineered the engine mount right in SolidWorks, but isn't that a Rapidform XOR screenshot that shows the CAD model over top of the scan data? Did you build the model in Rapidform and then transfer it over to SolidWorks? If so, did you do part of the work in RF and part in SW?

The heat shield (the lower picture in the post) is what I modeled right in SolidWorks, while the mount itself I scanned, cleaned up the data in RapidForm, then transferred that into SolidWorks to complete some of the finer details that are easier modeled in SolidWorks than RapidForm. Therefore, you are correct - the top photo is a screen shot of the work done in RapidForm before I transferred the date to SolidWorks.
