Layout - how to remove parts without removing routes?

dmeeks Jun 25, 2012 10:11 PM

I have a design that will be built with population options (some parts removed). I need to show assembly views with the build options - showing parts removed.

In layout, in ECO mode, when I delete a component, it removes traces. There is a dialog that pops up asking me if I want to remove routes, and I uncheck the box (don't remove routes).

But then another box pops up telling me that some other nets will be removed. These are nets that only go to one other pin.

Is there a way to remove parts without affecting the copper on the board?

Thanks

Dan

i think you can make use of the assembly variants feature without deleting parts

Yes.
The assembly variants option is great for such task.

You can do it manually too.

In Layout, select the ECO toolbar (you can set the ECO file to a dummy path; you won't use it).

Delete your parts (the copper will stay because this isn't part of the automatic ECO process).

Set the view options to not show unrouted nets (hide the ratsnest)

Generate your assembly drawings

Close without saving!

If you only do this occasionally this process isn't too tedious. If you do this a lot then the variant option is worth the money.
