Cgeom will not regen

Cgeom will not regen

Cgeom will not regen

(OP)
Hello.

This might turn into a long thread, so I thought I would ask a simple question first, and by itself, maybe it will answer the larger question, without a long diatribe.

Simply put, I have a part at a given accuracy. I did a PGEOM of the part and saved it out. Then I attempted to CGEOM it into a new blank file that had the same accuracy. But it failed regen. How can this happen if the original part regens just fine? I might add that it is a very complicated part.

Scratching my head.

And it gets worse...

I have a very complex part. Because of that, there were some small areas that had no simple solution but to go in and do Boundary Blend patches and a bunch of Solidify's. I don't like going that route because things can quickly get too complex and regen failures start to crop up like weeds. Many times, I have no solution but to tinker with the part accuracy, by lowering it enough that the problem features finally regen successfully. The problem here, is that when I try to cgeom features into another file that has a higher accuracy, it may not regen, forcing me to have to lower the part accuracy of that file, too. In this case, the original file has become trapped between a rock and a hard spot...I cannot lower or increase the part accuracy becasue now the model has become extremely sensitive to shifts in either direction. So I have an inflexible part, that does not want to relate to another file, or in an assembly. Also, I have noticed that when accuracy must be lowered, copied curves and surfaces do not always copy accurately, often times leaving gaps or overlaps that cause Solidify to fail.

I guess my question is, how do you build complicated parts without having to tinker with accuracy settings, and when patching features is required with numerous Boundary Blend, Trim, Extend, Solidify, etc., how to do it in a way that has a good chance of surviving regens?

I am solving the problem by basically redoing the last half of the features. This is the first time in 16 years experience with Pro that I have ever had to basically redo a part. I found a major bad decision in how I planned the part. All it takes is one to mess with the remainder of the file. As a result of the redoes, I have eliminated the need to do all of the patching I needed to do in the original, and therefore, eliminated the areas that were forcing me to have to lower the part accuracy. Will see if the good luck continues up to the finishing of this new version.

White Paper - Considerations for choosing a 3D printing technology
The adoption of 3D printing into major companies’ product development life cycles is a testament to the technology’s incredible benefits to consumers, designers, engineers and manufacturers. While traditional production methods have limitations in manufacturability, 3D printing provides unparalleled design freedom due to the additive method of building parts layer by layer. Download Now
