How to remove Copper "Graphics" from copper

Question

Hi!
How do I cut out the copper Plane? When I use the normal Polygon function, there is alway a small copper string all around the polygon and the parts. Using the Keep-In/Keep-out tool, I get errors when I place it over parts/vias/nets....
What is the correct way to do this?

Hi,
To use the keep-out to clear and copper area, you have to tell Ultiboard what to keep-out otherwise everything within the keepout area will give a DRC warning. To specifically tell Ultiboard what to keep-out, do this:
1. Tools»Group Editor»Net Group, click the Add button and assign a group name.
2. Assign the net to the group, in case whatever net the copper area below to and make it appear under Assign Nets
  Place»Keep in/out area, draw the keep-out area
4.  Double click the keep-out area to open its properties dialog, check the Net Group then Options, check the net group you created
The steps are similar to what is described in this, but you want keep-out instead of keep-in.
