Syntax

*surfacecreatespinlinewithoffsetangle mark_id rotation_plane start_angle end_angle options

Type

HyperMesh Tcl Modify

Description

Spins lines to create surfaces by specifying a start and end angle.

Inputs

mark_id

The mark ID containing the lines that you wish to spin.

rotation_plane

The axis about which to spin the lines (plane normal is used as axis vector and the base point of the plane is used as the rotation center).

start_angle

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

end_angle

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

options

Flags that indicate different modes. Bit values are used and the value is calculated as (Bit0 + 2*Bit1).

Bit0

Line merging mode. Valid values are:

• 0 – Do not merge input lines. A surface is created for each input line.
• 1 – Merge input lines into smooth lines when possible. A surface is created for each group that forms tangentially continuous line.

Bit1

Specifies how entities are organized into components. Valid values are:

• 0 – Surfaces are created in the current component.
• 1 – Surfaces are created in the most common input lines component.

Example

To spin line 2 from 45 to 90 degrees about an axis given by the vector (1 2 3) with rotation center at point (4 5 6), creating a surface of revolution in current component:

*createmark lines 1 2
*createplane 1 1 2 3 4 5 6
*surfacecreatespinlinewithoffsetangle 1 1 45 90 0

Errors
