This reply is just to say that I would also like more shapes and library items for construction.
Such as:
predefined concrete piers at industry diameters,
scaled lumber silhouettes (joists, girders, beams, headers, etc. in "1x", "2x" "doubled" etc.)
Also would like to be able to quickly define multiple points on a line at given spacing--such as piers on center under a girder. Am new to product so may have missed a tool for doing this.
Grouping multiple elements (lines and circles along a defined axis) is an action that would be useful...as I say, still learning.
