Post subject:  Cutting out a shape..

Hey guys -
Not sure what the proper terminology is, but I was wondering if there was a way to either:
(1) Cut out a shape from within another shape, or
(2) After the copper pour is done, cutting out a shape from it manually.

i.e. Let's say I have a square shape in my bottom copper layer. I then want a circle within this square where there is NO copper.
Or, for example, I have the same square shape, and I want inverse text in the shape.

To create a circular void in the copper pour...
1) Select Route Keepout in the Current Shape and Text Layer drop-down list.
2) Click on the Place Shape icon.
3) Select the empty Ellipse in the drop-down drawing objects menu.
4) Draw the circle on the copper pour (left-click and hold, drag shape and release; or left-click once to start shape, move mouse and left-click to end shape).
5) Update the copper pour to see the result. To make things a little easier, you can assign a hotkey to Update All Copper Pours if you are using DipTrace version 3.

For planting inverse text into a copper pour, it's a little more involved. See this thread - http://www.diptrace.com/forum/viewtopic.php?f=4&t=11711

Ah kosher, thank you very much.
I'm assuming that there's no way to create 'holes' in other shapes then, since you didn't bring that up. (Not a pour, but an actual shape that could be in Silkscreen, Mask, OR copper area as well..)

As far as I know, not for non-pour copper or solid silkscreen objects. You would have to modify a pre-existing shape to suit your needs by right-clicking on its outline, choosing Properties... in the pop-up menu and editing the Points table (or adding/subtracting points and/or moving its outline using the mouse). Another option involves importing the desired shape into the required layer via a DXF drawing file created using your favorite 2D CAD program. The Mask layer is used for creating custom openings in the solder mask.

Thanks Tom -
I'll give that a shot - I didn't know DXF's were supported (never occurred to me to try that..)
