*surfacesplinefrompoints

Creates a spline surface using selected nodes or points as boundary conditions.

Syntax

*surfacesplinefrompoints entity_type mark_id options

Type

HyperMesh Tcl Modify

Description

Creates a spline surface using selected nodes or points as boundary conditions.

Inputs

entity_type
The type of entity to use as input. Valid values are nodes and points.
mark_id
The ID of the mark containing the input entities. Valid values are 1 and 2.
options
Specifies options for creating the surface. Bit values are used and the value is calculated as (Bit0 + 2*Bit1 + 4*Bit2)
Bit0
Surface trim mode
  • 0 - Trim by parametric rectangle.
  • 1 - Trim by points boundary.
Bit2
Mesh stitching. Used to control the connectivity of the mesh created on the new spline surface in simultaneous meshing modes.
  • 0 - New mesh is not connected.
  • 1 - If *surfacemode is set to 1, existing mesh nodes are used if new spline edges are stitched to those lines.

Example

To build a spline from the displayed points and do not connect mesh:

*surfacemode 1
*createmark points 1 "displayed"
*surfacesplinefrompoints points 1 0

To build a spline from the displayed points and do not connect mesh:

*surfacemode 1
*createmark points 1 "displayed"
*surfacesplinefrompoints points 1 4

Errors

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