SURFPTS

Generates points on boundary surfaces previously defined by the surface or region command. The variable ** ** itype can be surface or region and iname is the name of the surface or region. 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. The point location for a region is determined by iregpt and can be on the inside, outside or both surfaces.

FORMAT:

surfpts/itype/iname/iregpt/ifirst,ilast,istride/geom/ray_origin

surfpts/itype/iname/iregpt/pset,get,setname/geom/ray_origin

Where ifirst,ilast,istride or pset,get,setname define the set of points to shoot rays through. SPECIFICALLY FOR ALLOWABLE GEOMETRY TYPES:

surfpts/itype/iname/iregpt/ifirst,ilast,istride/xyz/x1,y1,z1/x2,y2,z2/x3,y3,z

Where points 1, 2, 3 define the plane to shoot rays from that are normal to the plane.

surfpts/itype/iname/iregpt/ifirst,ilast,istride/ rtz/x1,y1,z1/x2,y2,z2 /

Where points 1, 2, define the line to shoot rays from that are perpendicular to the line.

surfpts/itype/iname/iregpt/ifirst,ilast,istride/ points /iffirst,iflast,ifstride/

Where ifirst,ilast,istride define a set of points to shoot rays from.
