hm_getboundingbox
Returns the bounding box of the specified entities.
Syntax
hm_getboundingbox entity_type mark_id entity_flag system_id box_type
Type
HyperMesh Tcl Query Command
Description
This command returns the six values defining the bounding box from the specified entities and options:
x_min y_min z_min x_max y_max z_max
The box values are determined depending on the following options.
Inputs
- entity_type
- The type of entity to find the bounding box for. See the list of supported entities for this command.
- mark_id
- The ID of the mark containing the entities. Valid values are 1 and 2.
- entity_flag
- This is a bit value used when entity_type is assems or comps.
- system_id
- The ID of the local coordinate system to return the values relative to. A value of 0 is the global system. Currently only rectangular systems are supported.
- box_type
- The type of bounding box to return. Currently, only a value of 0 is supported, which indicates to return the coordinates of the box oriented along the axes of the specified system.
Examples
To get the bounding box for the displayed elements oriented relative to the global system:
*createmark elems 1 displayed
hm_getboundingbox elems 1 0 0 0
To get the bounding box for the geometry in comps 1-4 oriented relative to rectangular system 100:
*createmark comps 1-4
hm_getboundingbox elems 1 2 100 0
