Model.create_thin_solid_midline

Model.create_thin_solid_midline(solid_collection, node_collection=Collection(), point_collection=Collection(), plane_by_point_coords=hwDoubleList(), plane_base=hwDoubleList(), plane_normal=hwDoubleList(), dest_comp='midline')

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

• By two sets of coordinates defining the base point and the normal vector of an infinite plane.

Parameters:

• solid_collection (Collection) – The collection containing the solid entities. The non-thin solids will be ignored.

• node_collection (Collection) – The collection containing the node entities defining the cutting plane.

• point_collection (Collection) – The collection containing the points entities defining the cutting plane.

• plane_by_point_coords (hwDoubleList) – The value should be a list of coordinates that determine the infinite or finite cutting plane. The list should contain 9 real numbers (3 sets of xyz coordinates) or 12 numbers (4 sets of xyz coordinates).

• plane_base (hwDoubleList) – The list containing coordinates of the base point defining the infinite cutting plane.

• plane_normal (hwDoubleList) – The list containing coordinates of the normal vector defining the infinite cutting plane.

• dest_comp (hwString) –

  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”, and so on 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, and so on.

  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.
