The shape to draw.
The view: the eye sits on the side the normal points to and looks back along it, and the drawing's x runs along the direction from the frame's origin.
OptionalexactWhen true, the drawing is made from the exact geometry; when false, from a mesh, which is faster and draws parallel views only.
OptionalsmoothWhen true, the edges where faces meet without a crease, such as the borders of a fillet, are drawn too.
OptionalhiddenWhen true, the edges that faces cover are collected in hidden; when false, hidden stays
empty.
OptionalfocusHow far the eye sits from the frame's origin along its normal for a perspective, in model
units; 0 draws a parallel view. A perspective needs exact.
OptionalprecisionThe meshing tolerance in model units when exact is false; a smaller value follows curved
faces more closely.
A shape, a view frame and drawing options for
operations.hiddenLines, which draws the edges seen from the frame and the edges hidden behind faces, flat on the XZ plane.
