I'm pretty new here so apologies if I'm asking something known - I've tried to search the forums for an answer but no luck so far.
I'm building a C model of the 42029 pickup using Ldcad 1.5 and I was planning to create instructions with Lpub3D. I made the mistake of not testing my .mpd during the building process with Lpub3D, so I've realized towards the end that the file cannot be opened, Lpub3D crashes when I try to open the file (Lpub3d***.exe has stopped working). As I did not have any other troubleshooting ideas I started to remove submodels and steps in my mpd going backwards to see if I can find the problematic part.
As it turned out the problem is not that simple - different versions of Lpub3D on different operating systems can open different versions of my file.
E.g. version with 8 submodels - opens with Win10/Lpub3d 2.0.14 / opens with Win7/Lpub3d 2.0.14 / opens with Win10/Lpub3d 2.0.14
version with 11 submodels - crashes with Win10/Lpub3d 2.0.14 / opens with Win7/Lpub3d 2.0.14 / opens with Win10/Lpub3d 1.3.4
version with 21 submodels - crashes with all versions (nearly complete model has 60 submodels)
Due to this inconsistency I could not find a single part or submodel causing the issue - above a certain complexity all versions of Lpub3D crashes.
I'm sure Lpub3d supposed to handle a model with ~1000 pieces, so I don't know at this point how to change my file to make it work. Any advise or suggestion would be greatly appreciated.
