**thicken_bset

Description

This command is used to add a layer of elements on a specified bset. This is sometimes necessary before using a boolean_operation.

Syntax

The command has the following syntax:

**thicken_bset \(~\,\) *bset bset-name \(~\,\) *height height-of-elements \(~\,\) [ *direction vector ] \(~\,\) [ *towards point ]

*bset

elements are attached to the specified bset. There is currently no default.

*height

specifies the height of the newly built elements (default is 1).

*direction

specifies a direction for the extension.

*towards

is an alternative to *direction: elements are built towards the specified point (or away from it, if height is negative).

Example

The following example extrudes the bset corresponding to the inner surface of a tube toward its center.

****mesher
 ***mesh thickened_bset.geof
  **open bset2thicken.geof
  **thicken_bset
   *bset inner
   *height 0.1
   *towards (0. 0.5 1.)
****return
