*linecreatenormalfromgeom
Create straight segment lines from a node or point normal to the respective geometry.
Syntax
*linecreatenormalfromgeom point_type point_mark_id geom_type geom_mark_id length ?mode?
Type
HyperMesh Tcl Modify Command
Description
This command creates straight segment lines of a user defined length from a given set of points or nodes normally to a given set of geometry entities. The segment is created for each pair of point and geometry. The input nodes/points must be attached or associated with their respective geometry.
Inputs
- point_type
- Type of entities representing input points. Valid values are nodes or points.
- point_mark_id
- The mark of input points or nodes.
- geom_type
- Type of geometry entities. Valid values are lines, surfs, faces or solids.
- geom_mark_id
- The mark of input geometry entities.
- length
- The length of the normal line.
- ?mode?(optional)
- Indicates different modes. Bit values are used and the value is calculated as (Bit0 + 2*Bit1).
- Bit0
- 0 - the normal direction is used, which is the default case
- Bit1
- Specifies how entities are organized into components. Valid values are:
- 0 - Line is created in the current component, which is the default value.
- 1 - Line is created in the input geometry component.
Example
To create a straight segment normally from node ID 10 to surface ID 21, with length
18:
*createmark nodes 1 10
*createmark surfs 1 21
*linecreatenormalfromgeom nodes 1 surfs 1 18
Errors
Incorrect usage results in a Tcl error. To detect
errors, you can use the catch
command:
if { [ catch {command_name...} ] } {
# Handle error
}
