Summary
Select two edges that define the mesh. The edges can be lines, arcs, splines,
circles, or polylines. If one of the edges is closed, then the other edge must
also be closed. You can also use a point as one edge for either an open or a
closed curve.
The MESHTYPE system variable sets which type of mesh is created. Mesh
objects are created by default. Set the variable to 0 to create legacy polyface
or polygon mesh.
For closed curves, the selection does not matter. If the curve is a circle, the
ruled mesh begins at the 0-degree quadrant point, as determined by the current
X axis plus the current value of the SNAPANG system variable. For closed
polylines, the ruled mesh starts at the last vertex and proceeds backward along
the segments of the polyline. Creating a ruled mesh between a circle and a
closed polyline can be confusing. Substituting a closed semicircular polyline
for the circle might be preferable.
