Autoadjusting pattern is unpredictable

#1 Post by Grebu » 15 Jun 2019, 04:44

When I create a pattern using a template for the pads, everytime I change the template spacing the rest of the pattern will be automatically adjusted in an erratic manner. The package contour, route keepout etc will change. The following pictures show that these adjustments are unpredictble and create a lot more work to undo the unneeded auto adjust then to actually help.

After changing the pad spacing:

Normally you don't need such a big change in pad spacing. But it clearly shows that everytime template spacings are adjusted the design gets messed up.

It would be great if there woud be an option to disable automatic adjustments by default. So far it never helped me but only created more unneccessary work.

It's comforting to see that I am not the only one annoyed by this behavior. Here's a blast from the past - viewtopic.php?f=8&t=10533&p=18270

We recommend to use Pattern Template for the first stage of pattern designing and edit the spacing manually, if the shapes are already placed.
