(ds:get-active-patch owner)

Arg Types:
|
owner
|
entity

|
|
Returns:
|
integer
|
|
|
Description:
|
Returns the tag identifier number for the active patch within the deformable model patch hierarchy associated with the input
owner.
|
|
|
Making the query on an
owner without a deformable model causes a deformable model to be added to the entity and a tag identifier value is returned.
|
|
|
owner ACIS face or edge on which the deformable model lives.

Example:
|
; ds:get-active-patch
|
|
; Add to a square test face a parabolic crv-load
|
|
; and use it.
|
|
; Build a test square spline face.

; (6x6 control points, x and y side length = 36)
