Curved Truss Concerns

[C. Andrew Dunning]

2 concerns I have in using the curved truss tool:

1) When 12" box truss arcs are created the lacing does not stay within the confines of the main chords (in 3D). The lacing sections stick out (above) around .3". This is when the ladder spacing arc is 22.5.

2) The radius dimension is the radius through the center of the truss - not the outer or inner radius. This is a little confusing in that the user has to remember to do a little math in order to create a circle or arc w. a specific radius or diameter (as such pieces are created in reality by the manufacturers).

Otherwise, a pretty useful tool. 99.99% of the time I use my own truss symbol set, but when I need a quick arc for which I don't have a symbol yet, this tool is indespensable.
