This is a nice sketchup video presented by Zent Design that shows the basic functionalities of SteelSketch Plugins as well as how it works with SketchUp 2015. This sketchup plugin supports sketchup 2014 & sketchup 2015. SteelSketch is used to create pipes and profiles extruding alongside linear entities.
By applying SteelSketch, the users can perform the following activities:-
Form a pipe through circular section extruding alongside a linear entity or arc.
Generate a pipe having rectangular section extruding along a linear entity or arc.
Produce a steel beam picking the section profile from a vast archive containing all the ISO standard sizes.
SteelSketch contains some useful commands like create pipe, create profile, get weight etc.
