Art there is still an issue with LC not doing a reverse import.
Problem is I have a part that i've done all the work on in lcam.  Including changing a lot of machine holes to a drill drill holes on a separate drill layer.  I next export it to Mach3 (.tap) and find some problem.  now comes the problem, when i bring the tap file ("Load Current mach file..")  back into LCAM it does not import the drill layer holes, completely missing.  So now i have to start over from scratch.  No i did not save the original file to "save lcam project".  don't need to do it very often and i always forget.

Am i doing somehting wrong or is there a bug.     

I think that is a bug.. Don't think we ever added it

pleas stick it on the list.  short list i hope
