hm_getsurfacenormalatcoordinate
Returns the closest point and the components of the normal vector at the point on the surface closest to the input coordinates.
Syntax
hm_getsurfacenormalatcoordinate surf_id x y z
Type
HyperMesh Tcl Query Command
Description
Returns the closest point and the components of the normal vector at the point on the line closest to the input coordinates.. The first 3 return values are the closest point coordinates, and the last 3 are the normal vector components.
Inputs
- surf_id
- The ID of the surface.
- x, y, z
- The (x,y,z) coordinates of the point.
Example
To get the components of the normal vector nearest the coordinates (100,50,25) for the surface with ID 341:
foreach {x y z n_x n_y n_z} [hm_getsurfacenormalatcoordinate 341 100 50 25] {}
Errors
if { [ catch {command_name...} ] } {
# Handle error
}
