Q: How can I resize beams and change only the wall thickness?
REV 5.08

A: When beams are resized, the possible sizes are defined by a selector. Thus, define a selector that only changes the thickness. For example:

     &SELECT :LEG -SEL P60@

     ~LEG TUBE 60 1 -RED :LEG

will resize using only the tube shapes in the table which are 60 inches in OD.
