Description

Constructs midline of a section cut through selected solids. The section cut plane can be defined using one of the following methods: by three nodes/points/sets of coordinates, by four nodes/points/sets of coordinates defining the corners of a finite rectangle or by two sets of coordinates defining the base point and the normal vector of an infinite plane.

Inputs

solid_mark=<mark_id>: The ID of the mark containing the solids. Valid values are 1 and 2. Non-thin solids will be ignored.
node_mark=<mark_id>: The ID of the mark containing the nodes defining the cutting plane. The mark should contain 3 or 4 nodes. Valid values are 1 and 2.
point_mark=<mark_id>: The ID of the mark containing the points defining the cutting plane. The mark should contain 3 or 4 points. Valid values are 1 and 2.
plane_by_point_coords={<value>}: The value should be a list of coordinates that determine the infinite or finite cutting plane. The array should contain 9 real numbers (3 sets of xyz coordinates) or 12 numbers (4 sets of xyz coordinates).
plane_base={<value>}: The list containing coordinates of the base point defining the infinite cutting plane.
plane_normal=<value>: The list containing coordinates of the normal vector defining the infinite cutting plane.
dest_comp=<value>: This option specifies which component the midlines will be created in:; current – Creates all midlines in the current component; midline – Creates all midlines in a component with the name “midline” (default); midline.# – Creates midlines in components with names midline.1, midline.2, etc. corresponding to the components containing the original solids.; original – Creates midline for each solid in the same component as the solid itself. If the solid lies in several components, the midline will be created in one of these.; original.# – Creates the midline for each solid in the component with the original component name suffixed with 1, 2, etc.; within_comp_only – Do not equivalence between components. to_connected_surfs - Equivalence between selected surfaces and surfaces connected to selection.; within_selection – Equivalence only within the subset of selected surfaces

Errors

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

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