*solidcreatespinsurfwithoffsetangle

Syntax

*solidcreatespinsurfwithoffsetangle surf_mark rotation_plane start_angle end_angle options comp_mode

Type

HyperMesh Tcl Modify

Description

This command creates one or more solids by rotating a given set of surfaces around a given axis.

Inputs

surfs_mark_id

The mark containing the surfaces that you wish to rotate to create solids.

rotation_plane

The plane whose normal is used as the rotation axis and its base point used as the rotation center. This plane is created using the *createplane command.

start_angle

Degrees value of initial rotation angle: selected surfaces are rotated by this value before solid “sweeping” begins.

end_angle

Degrees value of final rotation angle: solid “sweeping” stops at this value.

options

Flags that indicate different modes for solid creation. Bit values are used and the value is calculated as (Bit0 + 2*Bit1 + 4*Bit2 + 8*Bit3).

Bit0

0 – Only free edges of surfaces are rotated.

1 – Both free and internal edges rotate, thus creating boundaries between solids created from each individual surface.

Bit1

0 – Create solid entities.

1 – Create only the boundary of solids.

Bit2

0 – Selected surfaces become part of solid boundary.

1 – Selected surfaces remain intact.

Bit3

0 – Solid surfaces are ignored as input.

1 – Solid surfaces are copied and the new copied surfaces are used to create spin solids.

comp_mode

Determines how new solids are organized into components. Valid values are:

0 – Solids are created in the current component and boundary surfaces are moved to the same component.

1 – Solids are created in the current component but surfaces remain in their original component.

2 – Solids are created in the same component as the selected surfaces (the result is unpredictable if surfaces from different components become a part of the same solid body).

Example

To create a solid by rotating surface 1 around an axis defined by the direction vector (1 2 3) with a rotation center at point (4 5 6) and using a full 360 degrees angle, creating a solid in the same component as surface 1, and keeping the surface 1 intact:

*createmark surfs 1 1
*createplane 1 1 2 3 4 5 6
*solidcreatespinsurfwithoffsetangle 1 1 0 360 4 2

Errors
