Hi allOriginally posted in cdnusers.org by Richard Moffat
I've possibly found a new serious problem with shapes. I can't find the
exact problem in the archives, so I thought I'd throw it to you all
before I submit it as a bug.
We have a board with several negative shapes. Upon sliding a via, all
the shapes that either are in contact with that via or void around that
via, immediately become 'out of date'. It happens randomly.
Eg, it could be a GND via I am sliding, but all negative shapes around
that via effectively disappear, leaving only its outline. This leaves
thousands of unconnected vias, ie unconnected nets.
That's not the problem. The real issue is that any stitching vias on
these shapes are now disassociated with any signal. Updating shapes
will NOT work. The stitching vias now have a dummy net, and will stay
that way. (By stitching vias, I mean only those from shape-to-shape.)
Funnily, if you catch it soon enough, an undo will rectify it!
We're using 15.5.1, latest ISR, etc. We also really need to keep
negative shapes, due to the size of the designs.
Any clues? Has this been reported before?
