thanks. I will give that a shot.

I Might have figured out a little something but still struggling to get this right. I ended up using parallel to surfaces and it seems to be cutting the way I would like it to but only is finishing the floors not extending up the radius to blend with the walls like I would like. I replaced the newer file in the original post

Hi. I am looking for some help with a part I am trying to machine on our haas 5 axis machine. I attached the mcx7 file to help see what im talking about. Having trouble finishing the bottom floors and ribs of this part. How would you do it and could you show me an example. If you open the file and look at the stock model (op22) will show the part machined up to the point where I would need to finish the floors and ribs. Below that op was an attempt at doing a scallop and converting to 5ax. Problem is the fillet radius rolls from a .25 to a .19 when transitioning to the middle ribs. Im assuming this must be surfaced to achieve this. I have been in contact with the local mastercam support guy but he has been slow to get back with me. Hard to explain. thanks mike TEST.zip
