Broken-line graphics
In broken-line graphics, the contour is displayed with starting and end
points. The cloned elements are marked without starting and end
points. In addition, the lines of symmetry are displayed with dashed
lines. In program overview, the entire contour is displayed without
starting and end points and without lines of symmetry.
Chamfers and rounding
When mirroring, the contour is reflected in the starting or end point. A
chamfer or rounding can be added at this stage.
During repetition, the open contour is cloned to create a closed
contour. The number N shows how many parts are required to create
the closed contour. A chamfer or rounding can be added between
these parts. The direction of rotation for closing can be freely selected.
