Mastercam 2017 crashing with file merge from autocad 2019

[Geremy]

Good day to all!  I haven't been able to find anything searching through the forum, if someone can, please reply with a link.

We have MasterCAM 2017 and just upgraded to AutoCAD 2019.  Within AutoCAD, we save all files as 2013 for our saveas and w blocks.  We have a template MasterCAM file that we erase all geometry and file merge, then re-chain and save as.  Since we've upgraded to AutoCAD 2019, the file merge function in MasterCAM randomly crashes MasterCAM with no error warning.  Just disappears.  This has been happening seemingly randomly over the last week and we have not been able to find a consistent factor in the crashes.

With the files that do crash, we just re-do the process in AutoCAD and it seems to fix it.

Any help would be much appreciated.

Mastercam 2017 does not support files from AutoCAD 2018 & 2019. You should output them from AutoCAD as an earlier version file.

We have been saving all files as AutoCAD 2013.

Are you merging solid files, surface files or wireframe geometry?

[Geremy]

Wireframe geometry.  All z=0, lines, arcs, polyline with some groups and blocks.

Wireframe geometry

Do you use .dwg or .dxf?

[Geremy]

dwg

Are there any drafting entities in the dwg??

 

If so delete them...

Try saving as a .dxf  and see if that helps, it is generally accepted as a standard wireframe transfer file.

Never had a problem with .dxf files.

And with solids, parasolid x_t is a bullet proof file transfer protocol.....
