I'm receiving some product CAD files from a client. They're using NX Unigraphics, and I have them exporting STEP 203 and 214 files (as I have no idea what the difference is...).
But I'm immediately seeing some areas of bad geometry in MOI. I'm attaching a stripped-down section of just one part, which shows the odd sweep piece, inside a rounded curve. There arr more instances like this, elsewhere. I assume this is happening inside NX, but when the designer looks, he says it looks fine on his end.

So, is this something which is happening when NX is writing the STEP file?

Or is this something that is happening when MOI is reading the STEP file?

Or none of the above? Maybe it is, indeed, just bad geometry, or more specifically the method by which NX simple creates its files? These are real products, which are used to make the tooling and molds for the final pieces. So, I know whatever they are doing in NX, it's working fine for their production.

Anyone have any suggestions?

Thanks!
