The truss tool offers a quick way for drawing simple truss elements.
You can insert a truss in more ways:
- point to point (start end end)
- along a selected edge
- between two picked edges (their center points)
Define some truss parameters in the menue.
Modify the truss during the input process via arrow keys / ctrl+tab / home+pos1.
