I use the TubeWorks add-on for Solidworks, which was recently upgraded to SW2021. Typically, an IGS file can be imported into TubeWorks and utilized, quite rapidly. However, I have a particular IGS file which, when imported into TubeWorks, generates a dialog box stating "The extruded bar section box does not match any section box in the Resource Editor."
Converting the part to a SLDPRT file and back to an IGS file does not resolve the issue. Same with STP files.
Would it be correct to assume there is an issue with the part's cross section, an issue with the part being imported, and/or an issue with the Resource Editor ? What might I do to work through this?
