Hints, Tips and Solutions
Q: How can I cut exactly the same hole in many layers?
A: There are at least two ways to do this.
(1) You may use the command Tools>>Cut by Line as follows.
1.1. Set Cut by line mode to “All”.
1.2. Hide all layers where you do not want to cut the hole.
1.3. Draw a self-intersecting cutting line in such a way that the required shape of hole is drawn, see Figure 1. It is important that no “loops” of cutting line lie completely inside the cutting regions: such loops will be ignored.
