Is there a way to selectively Blank items?

wklane

Is there a way to Blank currently selected items?  By blanking I mean make it no longer visible but not deleted.  Layers can be turned off and cells can have their visibility dimmed but if I have 2 particular pieces of metal2  and a cell selected I  want to blank those while leaving other metal2 visible.    The work around is to write all selected objects to a file, delete selected, then read the file to replace the objects.  We just don't want to continually risk deleting data.  Thanks

    I think by "Blank" you're asking to control the visibility of specific shapes. I'm not aware of any way of doing this. I think it's somewhat risky as then you might fail to see something that's really in the layout.

    If however you wanted to do this without deleting and recreating, one approach might be to add a new purpose in the tech file called (say) "invisible" and then create a layer-purpose for each of your metal layers. Then set the visibility of that in the tech file to be off.

    All you'd then need to do is for the selected shapes do:

    procedure(CCFselectedInvisible(@optional (objs geGetSelSet()))
      foreach(shape objs
        when(shape~>purpose=="drawing"
          shape~>purpose="invisible"
        )
      )
      t
    )

    You'd have more of a problem changing them back because you couldn't then select them, but I guess you could fix all at once using:

    procedure(CCFallVisible(@optional (cv geGetEditCellView()))
      foreach(lpp cv~>lpps
        when(lpp~>purpose=="invisible"
          foreach(shape lpp~>shapes
            shape~>purpose="drawing"
          )
        )
      )
      t
    )

    Then define two bind keys using CCFselectedInvisible() and CCFallVIsible(). I quickly tested it and it seems to work OK.
