*surfacemarksplitwithlines

Splits a mark of surfaces with lines swept along a vector.

Syntax

*surfacemarksplitwithlines surf_mark_id line_mark_id vector_id trim_flag distance

HyperMesh Tcl Modify Command

Changes the number of lines used to display an existing surface.

surf_mark_id

The mark ID containing the surfaces to split. Valid values are 1 and 2.

line_mark_id

The mark ID containing the lines to use for splitting. Valid values are 1 and 2.

vector_id

The vector ID to use for the split direction. This is defined using the *createvector command.

trim_flag

Bit value defining the trim options (Bit0 + 2*Bit1 + 4*Bit2 + 8*Bit3):

Bit0: 0 - Sweep using the distance value; 1 - Sweep through the entire surface
Bit1: 0 - Project using vector_id in both directions; 1 - Project using vector_id only in vector direction
Bit2: 0 - Project using vector_id if provided and non-zero length; 1 - Project normal
Bit3: 0 - Do not create fixed points at line ends; 1 - Create fixed points at line ends

distance

The distance to sweep, if trim_flag is 0.

To trim surfaces 15 and 16 with all displayed lines along the z direction, using a max distance of 0.5:

*createmark surfaces 1 15 16
*createmark lines 1 displayed
*createvector 1 0.0000 0.0000 1.0000
*surfacemarksplitwithlines 1 1 1 1 0.5

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
