This command can only be used on parts that already have a toolpath. The command joins the different toolpaths together by replacing rapid movements to cutting. The "Chain cut" command creates a toolpath with only one piercing for all selected parts. "Chain" is often use in materials which are difficult to pierce.
Create parts and use the "Contour" command and place the lead on good positions.
Good contour for this can look as above.
Start the command and select the cutting quality. The quality can be Rough or X-rough since the quality is just between the parts.
IGEMS will automatically use the "Fence" option on selected parts. The parts are selected in the same order the fence line crosses the parts.
It is also possible to modify the way the jet will take between the parts.
