You will be creating the profile as 2D geometry, so you must start in Design mode in the XY environment.
Once you have defined the initial profile geometry, you must decide on how you want to cut the profile. EdgeCAM provides three main cutting strategies to generate Wire profiles:
Linked
Profile (Geometry menu)
Tapered
Profile (Geometry menu)
Transformed
Profile (Geometry menu)
You select one of these commands to generate the manufacturing information
(“Design Intent”) within Design mode. Wire Erosion is the only manufacturing
discipline in EdgeCAM that works in this way - all other modules create
all manufacturing information and toolpaths in Manufacture mode.
