alphacam-offset
Draw a rectangle with first corner in X0 Y0 and second corner X600 Y400.
alphacam-rectangle
If you do not have any geometry in the workspace options in the Edit tab are inactive.
Now you can select Offset. Window appears:

Complete as illustrated and click OK.
Now Alphacam asked to select the geometry to offset.
alphacam-offset-select
Select rectangle and now we have to pick side to offset.

We can click inside or outside the rectangle. In this example please click inside the rectangle.
Offset command is still active. Click RMB or Esc to exit the command.
alphacam-offset
We received a rectangle reduced by 2 mm on each side.
Distance parameter determines the offset distance.
Geometry parameter specifies that you want to offset the entire geometry instead of eg. a single line.
