Weld, subtract and offset outlines

Use Ctrl+K inside LaserStudio to find these commands. Weld and Subtract take two closed rectangles, ellipses or polylines on the same layer. Select the first object and Shift-click the second.

Weld overlapping shapes

Choose Weld selected outlines to create the outside boundary of two overlapping shapes.

Subtract the second shape from the first

Choose Subtract second from first. To make a hole in a rectangle, select the rectangle first, then Shift-click the circle inside it. The first object is the part you want to keep.

Add an offset around one outline

Select one supported closed outline and choose Offset. Enter a positive value to expand or a negative value to contract. Offset adds new contours and retains the source. For an offset applied only during job generation, see kerf width and side.

Check sampled results

These tools generate sampled polylines. Save a copy before welding or subtracting because those commands replace the input shapes. Check the dimensions, corners and small details. Preview both the outside contour and any opening before preparing output.
