3D Scallop getting "Internal CAM error"

I'm trying to do a scallop cleanup op of a domed surface and I can't get a toolpath to generate. The roughing spiral CAM for the dome generates with no problem. I've looked at forums and YT with no luck. I suspect I am doing something wrong as this is the first 3D curved part I've attempted. What might be related is that I can't even seem to see in the geometry tab where I select the surface I want to cut, though in the videos I've watched a surface never seems to be selected, but a toolpath is still generated (in the tutorial videos, not for me) File attached. Thanks in advance.

Hmm, it does appear that Scallop does not like that surface one bit.

However, you may be able to find a suitable solution in Morph:

I've attached the file and will get the Scallop issue logged as a bug

I think I may have found the "Why". It might have to do with your tool size. If I drop the 4th and 5th place decimal of the tool (.15625) down to .156", we get a toolpath. If I use a .187 or .375 Ball endmill, I get a toolpath.

 

If I go back to a math function of "5/32", it returns .15625 and fails. If I manually type in .1562, it succeeds:

And it looks like this is covered in CAM-33813 already. It looks like the kernel is having some rounding issues between cutter diameter and tool radius value

Thanks so much.
