Find the overlapping shapes between three layers

Anmoljot

Hello,

We have a requirement as shared below:

  • Finding the overlapping shapes between multiple layers
  • Updating an existing layer by adding the shapes found in the previous step.

Kindly refer to the below image for the further description of requirement shared below:

Figures 1, 2 and 3 show the shapes for Layer A, B and C respectively and the Outline layer shape.

The requirement is to do an equivalent of "AND" operation to get just the shapes that overlap between the three layers.

The second part is to add these shapes to the OUTLINE layer as shown in the figure 4.

The smaller shapes in the middle region of fig. 1, 2 and 3 are not overlapping and hence not appearing in the output figure 4.

Please help to provide Skill commands which can meet the requirement.

Kindly let me know if any further details are required.

Thanks,

Anmol

  • I am wondering if there are any commands in skill that can help to select shapes of a layer having width greater than a certain value.

    Thinking of this as a workaround to filter out the smaller shapes (that are non-overlapping) and then I would be left with the bigger shapes only.

    Kindly suggest if there is any such command.

    Thanks,

    Well, it doesn't "select" them, but the standard trick to filter small shapes out is to undersize them (e.g. using abeLayerSize with a negative size) and then oversize them again with the same size. If you use half the minimum width you want for the undersizing and oversizing, then they'll be filtered.
