In regards to CNC... I have two CNC machines; one for tube and pipe, and one for channel and angel. I use the NC scribing settings in Management Tools. It is great that AS will scribe the outside shape of the single part being welded to the main part. However, it would be even GREATER if AS could also show the orientation of the object... such as a clip angle. If AS could scribe another line to show which side the leg of the clip angle goes on, it could eliminate the need for shop drawings, and/or a skilled craftsman to layout stairs per say. You would just need a competent welder.
