Yes i read too fast and composite holders can only be stacked between them. With cylindrical extensions i usually tweak segment length to mimic its projection.

In the standalone manager, You can stack the extension on top of the holder, but you cannot define a stickout length. So, what we do is assemble the holder, check the extension stickout and model the extension to the appropriate length, then marry them together. What we end up with is a multitude of the same extension modeled at different lengths.. Absolutely the biggest mess that CNC needs to address, This halfa$$ sometimes use this manager and other times use that manager to try and define tools correctly is an insane time waster.

That is not wear comp that is Radius comp huge difference.

Hi Daxman77, After you have selected the contour tool path type there is an option under the cut parameters tab on the right side that states contour type and in that drop down you should have 2D, 2D chamfer, RAMP, Re machining and oscillate. If i am wrong please correct me, as i am not sure how to check what i have, but believe i do have router 1

That's ok, you can be wrong...I've been doing this a LONG time...

I despise solid edges....lack of toolpath control and the inability to import ops with solid geometry negate my use of them, as such, I don't use solid edges. Plus I'm not looking for the lazy way and I want exact control over my paths.

Bitangentcy is the maximum acute angle where the software still looks for material. If you draw two line at a 90 degree angle and put a fillet of say .125" between them, you will clearly see the "remaining material". Now if you draw another two lines where the angle between them is say 120 degrees and fillet them with the same .125" rad, you will see much less "remaining material. As this included angle increases to 180 degrees ( a straight line ), the fillet gets smaller and smaller. Once you get to roughly 170 degrees, the remaining fillet would be "almost" zero. Basically, by setting the bitangentcy angle, you are telling Mastercam to ignore the small amount of leftover material. I think 170 degrees is default, but you can set it to whatever you like. I think an appropriate value would be between 160 and 170 degrees. Carmen

Looks like someone else hits "regen all dirty" a little too often as well..
