Comments

This statement can be used to create a 3D geometrical curve graphic that uses a 3D Cartesian Curve entity (defined using *Curve and *SetCurve).

The curve is in 3D space and is constructed using the X, Y, and Z data specified in a reference marker frame.

When BODYPT method is chosen, the curve is created on the body and the reference frame (int_marker) is internally created using the origin point as the origin of the marker. This internal marker needs to be oriented using the *SetOrientation statement. Otherwise by default, the orientation will match Global Frame. Refer to Example 1 (above).

When the MARKER method is chosen, the curve is created on the parent body of the ref_marker.

Curve graphic can be used to define Curve-Curve contact using a *TwoDContact statement.

Use *Set(property, value) statement to flip the contact side of the curve if needed. Here property can be set to gr_varname.is_material_inside and value can be set to Boolean (true or false).
