With the Hole Line 3D

  tool you can create multi drillings on each side of a cabinet. Choose a grid to be shown on each side of the cabinet. Then click to place one drilling in single mode

or to place drillings on all grid points in Multi Mode.

In the preferences you can choose diameter, depth etc.

When choosing the third mode »relative to the Custom Parts« the hole line is dependent on the height of the cabinet's bottom. Select the fourth mode »relative to the cabinet« so that the hole lines of the sides and partitions marry up.

Hole lines can also be created on Custom Parts. As soon as you duplicate a single drilling in a grid (that can be configured in the Production Settings dialog on the Machine tab), the drillings will automatically be converted into a hole line in CNC export.
