Problem lathe verify

[David Colin]

I experience a problem with verify lathe toolpath on 3D stock (solid/STL/Stock model)

It seems mastercam verify simulator doesn't spin stock around its X axis (looks like it calculates a gravity point or symetric point, I don't really know...)
 

I uploaded a file to test, you can use solid on level 1 (named STOCK) to verify.

 

Anyone noticed that? It's really annoying as i often program mill-turn parts (without mill-turn add-on of course...)

 

Here is a capture from X9 verify(incorrect) and a capture from  X3 (because i recently jumped from X3 to X9!) which is correct (looks like solid on level 2 named DESIGN)

I post on official forum too and bug is now logged as R-05663. Hope this will be fixed soon.

I am not sure that this is a bug.  See the screen shots below, this is what I get whenever I verify your part from X9.  It may be a setting in your program, in the Simulator Options, do you have 5-axis set?

It seems you are verifying with stock from job setup in you verify settings (as it s a lathe file, it means mastercam uses a solid made from a 2D chain revolved. The same it has calculated to generate lathe toolpathes). In that case it s correctly revolved around X centerline.
But, as you can see, that setting is ok to verify a lathe toolpath only, but it's not, to verify a mill toolpath (because stock will never stop to rotate)

So, to reproduce problem, in your verify settings, choose stock from a solid (and pick the one on level 1 named STOCK) then verify (you will also need to verify lathe toolpathes, not only milling). You will see lathe centerline is 'somewhere but clearly not on X axis'. However, milling toolpathes will verify correctly (stock will stop spinning)

I already tried stock model and STL file to set stock verify and it s the same problem.
