DXF pocket behavior

Postby Stuart Douglas » Wed, Jun 05 2019, 12:50PM

Anyone running the NEW CN update getting funny behavior with cutting round pockets? I use a pocket operation to cut the wire holes in diewall studs and the broken circle geometry (break the circle into two arcs, otherwise it is a drill operation) shows as only one of the segments in the nesting diagram, and doesn't cut at all. If I change that geometry to the chaincompin layer, it likewise only recognizes one segment and doesn't cut like it nnormally does.

I'll try to get a file up after I limp through these three sheets today.

What is the fastest way to roll back to the previous version? I didn't see any options in the menu trees.

Stuart,

I have not checked how you are doing it yet, but I usually advise our clients the following when it comes to Layered DXFs...

CIRCLES – aka closed arcs - When used on a DRILL layer (a “hole”) should be a one-part entity. When used on a POCKET layer, it must be broken into at min two pieces (2 arcs). !!! If your OUTLINE for a part is a CIRCLE, you must also break it up into at least two pieces (2 arcs) !!

Note: When dealing with “holes” (circular features within a part), it is always best to place the circular geometry on a DRILL layereven if you do not have an actual drill that matches the “hole” size. With CIRCLES on a DRILL layer, Control Nesting will:

• First look for a “real drill” that matches to perform a DRILL operation.
• If no “real drill” is found, Control Nesting will look for a router bit that can INTERPOLATE the “hole”.
• If no INTERPOLATION tool is found, an attempt will be made to POCKET the “hole” with the available POCKETING tools. (Splitting is done automatically.)

Sorry for the trouble. We have found an issue with arcs importing from DXF in version 6.12. This is what is causing your problem. We will have a new version that resolves the issue very soon.

I had originally thought I had forgot to break my pocket geometry into two arcs but that is not the case. I'll have to change my protocol to see if the "drill" secondary and tertiary methods will allow this to work. Larry: I know its no consolation to you programmers, but I'm glad this one isn't me! It usually is some siple dumb oversite.

I got my holes cut using the method mentioned in the above posts using the DRILL command and subsequent parameter tree, but it looks like the DXF arc bug is pervasive. One side of the stud has proper dogbone corners, but the other side cut them "inside out"? See attached.

Version 6.13 should resolve these issues. It is now available.

and for rolling back a version simply run the installer for an old version it will over write it

Well, that's a lot simpler than I thought it would be. :shock: :oops:
