Very simple object, for use in geometry underlay views, usable first for figuring out and laying out the project, and then for checking at a glance for drafting or modeling accuracy problems. Ages ago I did those geometry layouts (using layers, worksheets, design options; or a combination; whatever works better for the project) with lines-polylines-arcs, but the beauty of objects is they have mutlistory display settings and also allow for composing the plan/section with fewer (so less room for errors; and easier to modify) complex parametric elements.
Object at https://www.dropbox.com/scl/fi/jo6ggx2b3wgg3syppabkh/IA-drafting-aid-27-260727.gsm?rlkey=jhypyid1kw4.... Version is 27 (saved down from 29), but it is really basic GDL and it should be saveable down to like 14.

[Philosophically: horrible things happening in let’s call it BIM with users not trained in basic drafting. I wish the world at least read the parts in Guadet on architectural drawing. I put up a Spanish translation in http://www.ignacioazpiazu.com/samples/Guadet-dibujo-2020-200609-1.pdf and there are the original French and I think English versions out there.]
