*solidcreatespinsurfwithoffsetangle

Create solids by rotating a set of selected surfaces around a given axis.

Syntax

*solidcreatespinsurfwithoffsetangle surf_mark rotation_plane start_angle end_angle options comp_mode

Type

HyperMesh Tcl Modify Command

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

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
