Here is a pic of the where the direction page is under surface parameters....
As far as I know the one limitation is that you can only retract in one direction...
Once it roughed out you could use parallel to multiple curves to get a decent toolpath. There are some good sample files in the shared folder....(C:\Users\Public\Documents\shared Mcamx6\mcx\mill\samples\inch\Multiaxis).
Then under roughing you can set it to use depth cuts and get a decent toolpath.

Spaceclaim does change STL files to solids easily. BUT, it seems limited once the size of the STL get bigger. I tried an STL file with only 30000 faces and exported to STP. Mastercam could not open it. Not sure if anyone has any suggestions?
if you put a file on the FTP site, maybe we could look at it and make some suggestions. See important topics at the top of the forum for FTP instructions...
When you are plunge milling you can set a retract at an angle so that your cutter does not rub straight up the plunge you just took. This will increase the insert life tremendously. Not sure if Reko used this method but it certainly helps cutter life.
I have found that it really depends on the mesh that you have created. Sometimes an offset on a mesh that is not clean on the edges can create a problematic offset. Usually I offset to see the result and then go back and add points or trim the point cloud until my offset looks good. Then I will refine/smooth.
