hm_getwrappoints

Returns a list of points, from the first input point to the third input point, that trace a convex path across the specified entities.

Syntax

hm_getwrappoints entity_type mark_id x1 y1 z1 x2 y2 z2 x3 y3 z3

Type

HyperMesh Tcl Query Command

Description

Given a mark of entities, a plane definition, and a vector, returns the maximum and minimum coordinates on the cross-section defined by the virtual intersection of the entities with the plane, in the vector direction.

Inputs

entity_type
The type of entities to consider. Valid values are elems, surfs and comps (elems take priority over surfs).
mark_id
The ID of the mark containing the input entities.
x1
y1
z1
Defines the normal coordinates of the first input point.
x2
y2
z2
Defines the normal coordinates of the second input point.
x3
y3
z3
Defines the normal coordinates of the third input point.

Example

To get the wrap points for all displayed elements using input points (0,0,0) (10,0,0) (10,10,0):

*createmark elems 1 displayed
hm_getwrappoints elems 1 0 0 0 10 0 0 10 10 0

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
