Hello, ever since I updated to 2020, I can not make custom lathe chuck jaws like I used to, so I have been making programs without them. The problem is that when I choose to use a chain to define my jaw profile, MasterCam then wants the reference point to be in the bottom right-hand corner of the most extreme entities, and this point must be touching the jaw profile, but in the majority of jaws I want to design it is not. And I can not for the life of me figure out how to get around it. I know there is a parameters tab there with a button to reset the reference point, but it gets greyed out when using a chain. I am running the most current version. Any help would be appreciated. Thanks Chris
hello gcode, that is very close to the fix I used on my part, but using your method would allow more complicated splines to be simplified.
Thanks for the suggestion
Hi JParis
I tried your suggestion, but the posted code was the same as it was using 0.025 tolerance. In 2017 reducing the linearization tolerance brings the points of the spine much closer together in the post producing a less faceted surface.
Thanks anyways though.
the pic is from mastercan 2017 lathe finishing parameters using a nurbs spline as geometry. When using mastercam 2018, the Linear Tolerance field window is missing and the spline is interpolated roughly when machined. I solved this particular problem by simplifying the spline to an arc and reposting. But I need to have a better solution going forward. Any help would be appreciated. Thanks

Hi I just updated to Solidworks 2016, and I tryed to merge a Solidworks 2016 part into Mastercam X9, but I keep getting "Cannot find Parasolid data in SOLIDWORKS file" message. I tryed this fix I found on this forum
right click on CMD.exe and run as administrator
then run the following in CMD
C:\windows|syswow64\regsrv32.exe "C:\program files\mcamx9\common\swoksdata\swdocumentmgr.dll"
But I keep getting the same message.
Any help would be appreciated
