hole recognition

[matthew omeara]

Hey,

New user here - I do cabinetry. The woodworking forum looks sparse, so I'll post here instead. I'm trying to find a work-flow using Cabinet Vision. CV exports DXF files using 8-sided polygons to represent holes rather than an arc. What are my options here? I'm just getting my feet wet with MC, so I'm not sure if there's a feature recognition that works in this case?

Matthew,

I think you're out of luck.

Mastercam is not going to automatically find these holes for you... and it gets worse

Unless your software exports a point at the center

of the hole you're going to have to draw some geometry.

Without seeing your files, my first try would be

to use the arc/tangent/3 lines command.

That will give you an arc.

You can then select them as enities, one at a time

or use the All/Mics/diameter selection method.

If the holes are equally spaced create one

circle and do x form translate as many as needed

To create center points - go to setting - configure - cad settings - and set automatic center lines to on then create a fillet on two sides of the octagon with a radius equal to the hole radius this will create points at the center location of the holes - if circles needed

create them at the points by locking autocursor

to points and locking the raduis setting

I dont know that creating an arc tangent will give you the result you want. If not try create arc 3 points and pick the intersect points of the octagon.

...whether the arc needs to be circumscribed or inscribed...
