The ISOLINES system variable controls the number of tessellation lines used
to visualize curved portions of the wireframe. The FACETRES system variable
adjusts the smoothness of shaded and hidden-line objects.
Methods for Creating Wireframe Models
You can create wireframe models by positioning any 2D planar object anywhere
in 3D space, using the following methods:
Use the XEDGES command to create wireframe geometry from regions,
3D solids, surfaces, and meshes. XEDGES extracts all the edges on the
selected objects or subobjects. The extracted edges form a duplicate
wireframe composed of 2D objects such as lines, circles, and 3D polylines.
Enter 3D coordinates that define the X, Y, and Z location of the object.
Set the default work plane (the XY plane of the UCS) on which to draw
the object.
Move or copy the object to its proper 3D location after you create it.
Wireframe modeling is a skill that requires practice and experience. The best
way to learn how to create wireframe models is to begin with simple models
before attempting models that are more complex.
Extract Curves from Surfaces, Solids, and Faces
When working with surfaces you may want to create non-mesh wireframes
displaying the contours of a surface to experiment with and regenerate
variations. The SURFEXTRACTCURVE command allows you to create lines,
plines, splines, arcs, or circles, depending on the surface, solid, or face selected.
Use the Chain option to preview and extract adjacent curves. After modifying
extracted curves, use the LOFT command to regenerate a surface that passes
through the extracted objects.
NOTE Adjacent faces, for solids and surfaces, must be parameterized in the same
direction.
The direction option allows you to extract curves in the other direction. Isoline
curves are extracted in the U direction, by default.
Choose the spline points option to extract a spline that passes through all
specified points on the surface.
