A bit of a strange one this.
I've built a part from sheetmetal which has various cutouts and holes.
One of these cutouts is for a binding post which has a notch I want to locate at a 45 degree angle.
I've added Centrelines which have been set at 45 degrees off horizontal / vertical.
I've then used those centrelines as a reference for adding the notch:
This appears to be fine.
I save the sketch then once back to the part, I extrude the sketch to generate the holes. That works fine.
I then pattern the extrusion 9 times. Again all appears OK.
I can regenerate the part, everything is fine. I save that part as "base-rear".
However now that I've used that part in an assembly "9ch-short", the assembly fails at regeneration with the following message:
9CH-SHORT regeneration completed with atypical feature or component status. Failed: 1. Child of Failed: 8.
BASE-REAR feature (ID = 9865) referenced by pattern is missing.
The Regeneration manager gives me this:
This appears to be linked to the diagonal centrelines. If I go back into the part and delete the smaller binding post cutouts with notches, the assembly is fine again.
What am I doing wrong?
