Bevel Chamfer Option

Description

Previously when no bevel was set for a seam or boundary, the system to some extent assumed a bevel type 10 (square butt welding). The benefit here was that chamfer was taken in to consideration when such an edge was included in an abutting boundary.

When the option 99 was introduced to the CHAMFER_ADJUST default keyword this faulty way of handling edges without any bevel was removed. This has caused problems when reusing old designs since the behaviour now is different.

In order to get this default behaviour back in older designs, an environment variable, SBH_DEFAULT_BEVEL, has been introduced and should preferably be set to a tight butt bevel type that is defined in the bevel control object.
