Mark geometry as cosmetic element
Use this command in order to mark geometry as cosmetic elements.
Marked elements are not visible in 3D, however are visible in the 2D derivation.

Note In order to draw threads please use the functions Cylindrical thread by length and Conical thread by lengths. See Section 7.9.3.13, “ Modify -> Threads ”.
Apply individual attributes which later will be transferred together with the marked element into the CAD system
Via Group elements into a spline, single arcs can be grouped into a spline.
If a part has a curve with variable radius, you have to approximate their form by using several single arcs (Arc through 3 points on circle, see following figure). Now the spline feature enables to export a grouping instead of single arcs. As a result the error rate is reduced, especially when using the blend feature. Furthermore the depiction in 3D is more precise.
First single arcs are drawn and then the spline feature is used.
