*nodecreateatplaneintersection
Create nodes or points at locations of intersection between the input geometric entities and a plane or vector.
Syntax
*nodecreateatplaneintersection entity_type mark_id plane plane_use point_flag
Type
HyperMesh Tcl Modify Command
Description
This command creates nodes or points at locations of intersection between a selection of input geometries and a plane or vector.
If there is overlap (continuous intersection) between the entities, the result is undefined. For example, finding the intersection of a line that lies exactly on the specified plane is undefined and can return unexpected or varied results.
Inputs
- entity_type
- Type of input entities.
- mark_id
- The ID of the mark of the first entity type. Valid values are 1 and 2.
- plane
- Input temporary plane ID (if plane_use is 0) created using *createplane or vector ID (plane_use is 1, 2 or 3) created using *createvector. This should always be set to 1.
- plane_use
- Parameter specifying whether input data specified by plane parameter is interpreted as a plane of vector. Valid values are:
- point_flag
- Parameter specifying whether nodes or points are created. Valid values are:
Examples
To create nodes at the intersections between the line with ID 12 and the plane z=2:
*createmark lines 1 12
*createplane 1 0.0 0.0 1.0 0.0 0.0 2.0
*nodecreateatplaneintersection lines 1 1 0 0
To create points at the intersection between surface 10 and a ray that starts at point (1, 2, 4) and propagates in the direction of y axis:
*createmark surfs 1 10
*createplane 1 0.0 1.0 0.0 1.0 2.0 4.0
*nodecreateatplaneintersection surfs 1 1 2 1Errors
