Overhang is not functional. Finish is the amount of stock you want to leave for another finish pass. So you would clean out the area and then make a finish pass.

BTW This particular profile is a PITA!

cpayne,
For this PITA file just take one read of the attached file before going to bed and then
apply  the verbage  to the attached Lcam.  :D

I have seen this kind of problem when trying to do a pocket. When it dosen't work, which can be due to a whole
bunch of things, the drawing, the tool, practical machining approach, corrupted file. Sometimes it's just better to take a different approach and it will get pocketed. BTW, i tried to pocket it with a different program and it was even worse. You won't pocket something if you can't create an offset for the profile. So that is always my 2nd option after a check of the drawing.
Please note that i wanted to do this using  an 1/8" end mill. with smaller cutters it probably would have been easier i guess.

Yup.....see that now, Thanks.
Never had THAT change before. Always at .0001, till now.

Decimal precision is saved in the .dxf file. So when you open it, it **should** change the settings in your CAD program as well.

Well after much fiddling and what not, I decided to try to draw the pocket cuts in CAD.  I managed to get the outside and inside offsets as one continous chain.    In drawing the offsets in CAD (Solidworks) i releasized why LazyCam had trouble with it.  Just offseting the lines kept creating all sorts of illegal overbound situations, but I finally faked it inot working.   Next is to try it out and see what happens.   THe issue will be as I need to make tweaks to the design, etc I will have to manually repocket it or manipulate it so lazycam can handle it each time, both time consuming...

THanks for all the help.
