Turning on/off etch selection by net/class/group

IMAN77

Is there a way to turn on/off etch selection by net/class/group in Allegro? 

What I'm looking to do is to be able to select only the clines and vias of a specific class to make a subdrawing (route reuse). The buss is routed on several layes with vias along the way and I want to be able to window-select only that buss on all used layers.

In order to do that I need to make everything else unselectable. Using FIX or making the other etch the same color as the background doesn't work as it is still selectable when creating the subdrawing.

Using the search in the forum didn't turn up anything on this subject.

Thank you!

  • You can use a Temp Group, so invoke the subdrawing command then right click - Temp Group, choose your objects by window or left click, if you get items you don't want you can CTRL + left click to deselect them, once you are happy right click - Complete, pick an origin and save. You may also be able to select only the required objects using a Find by Query but you may need to experiment with this.

    Thanks a lot Steve! So far it  looks like this is the only to do it. I come form Mentor where you can turn off all etch and then just turn on only the class you are interested in. What has been turned off becomes unselectable. This is especially useful when you want to reuse busses that are scattered all over the place (I know, not ideal, but some clients require you to do that).

    If I find a better way to do it I'll come back with an update.
