how to use "by box entity id" ids for createmark?

Rachit Semalty

Hi all.  I want to know how to use  "by box entity id" ids to select components within a number of boxes. How to create boxes? May it select components those have some of there part within the box?

Thanks and Regards,

Rachit

I've never saw these entities before, but apparently they're auxiliary entities that you can create and use for some selection. Boxes can be box, cylinder, spheres. I believe they're mostly used by RADIOSS.

For components this can't be used. Use "by box" instead.

Boxes

Box entities are enclosed volumes, which are represented by a box.

Nodes, elements, lines, and surfaces can be reviewed and saved within a box.

Radioss Cards

Card	Description
/BOX/CYLIN	Describes a cylinder box for entities selection.
/BOX/SPHER	Describes a spherical box for entities selection.
/BOX/RECTA	Describes a rectangle box for entities selection. Note: Block Format Keyword

 

 

 

"by box" x0 y0 z0 x1 y1 z1 syst location contained all tolPlace entities on mark_id, if they are inside/outside/on the boundary of the box.

• x0 - lower bound x coordinate.
• y0 - lower bound y coordinate.
• z0 - lower bound z coordinate.
• x1 - upper bound x coordinate.
• y1 - upper bound y coordinate.
• z1 - upper bound z coordinate.
• syst - the ID of a local coordinate system to which the coordinate bounds are relative to. If 0, the global axes are used.
• location - The location of the entities to find, relative to the shape. Valid values are inside, outside, boundary and acrossboundary.
• contained - A flag that indicates whether the entire entity should meet the location criteria (1) or just any part of the entity (0) to be selected.
• all - A flag that indicates whether all entities (1) or only displayed entities (0) are considered for selection.
• tol - The tolerance to use. In most cases, this should be set to 0.

This is currently supported for nodes, elements, connectors, components (FE and connectors only), loads, equations, loadcols, systems, systcols, vectors, vectorcols, blocks, groups, sets and contactsurfs.

"by box entity" ids or names"

by box entity id" ids

"by box entity name" names

Place entities on mark_id, if they are displayed within the bounds of the listed box IDs or names. The smaller of the global node tolerance, or 1/200 of the smallest block dimension, is used for the selection tolerance.
