DSURF, KCN, XSURF, YSURF, ZSURF
Defines the surface upon which digitized nodes lie.
KCNSurface is located in coordinate system KCN.
KCN may be 0,1,2 or any previously defined local
coordinate system number.
XSURF, YSURF, ZSURFInput one value to define the surface constant. Input 999
in the other two fields. Interpret fields as R, θ, Z for cylindrical
or R, θ, Φ for spherical or toroidal coordinate systems. XSURF and YSURF default
to 999 if KCN = 0.
Defines the surface upon which the nodes to be digitized (with the DIG command) actually lie. Surfaces are defined by a coordinate system number and a coordinate constant [MOVE]. Two coordinates are determined from the drawing and converted to surface coordinates. The third coordinate is defined from the input surface constant. If nodes lie on warped or undefined surfaces, use the DMOVE command.
