Generates points on boundary surfaces previously defined by the SURFACE or REGION command.
The points are generated by shooting rays through a user specified set of points from an origin point, line or plane and finding the surface intersection of each ray.
surfpts/ itype/iname/ inside outside both/ifirst,ilast,istride/geom/ray_origin
itype is the name of the surface or region.
ifirst,ilast,istride or pset,get,psetname define the set of points to shoot rays through.
inside outside or both indicates the point location for a region relative to the surface.
The parameters geom / ray_origin are the geometry and ray origin with parameters based on the geometry.
xyz/ x1,y1,z1/x2,y2,z2/x3,y3,z3 where points 1, 2, 3 define the plane to shoot rays from that are normal to the plane.
rtz/ x1,y1,z1/x2,y2,z2 where points 1, 2, define the line to shoot rays from that are perpendicular to the line.
rtp/ xcen,ycen,zcen where point is the center.
points / iffirst,iflast,ifstride define a set of points to shoot rays from.
