Thank you for the suggestions gang! I spent the day troubleshooting without any success. Here’s were things get a bit odd… On further inspection, I can process the previously attached SLDPRT fine by it’s own, it’s only when looping over that part and another part(s) does the crash seem to happen.
@menno - I integrated the UnhandledException Event example into my console app, but it doesn’t seem to work for this exception.
What I’m doing with my console application is looping over *.SLDPRT files and saving them out as .3dm files. Using a single RhinoDoc in the session to do this. At the end of each part, I clear all RhinoDoc objects with -
foreach (var obj in doc.Objects)
doc.Objects.Purge(obj.RuntimeSerialNumber);
Below is the full.cs if anyone has any other ideas on how to handle this? Attached is also the .cs document as well as two test .SLDPRT files. Just place the two parts in the same folder, pass the folder path of the two parts as the argument into the app.
I could be very wrong, but it’s almost like the RhinoCore itself is throwing some sort of exception, not the console app. Thank you for following this! Just purchased a Rhino license, coming off an eval, and hoping there is a solution to this or I’m skunked!
