![]() So far so good, and I can make further entities of similar form as copies, and place them by their own plotting-centres. E.g., join 2 rectangles to form a 'T' and the centre moves axially towards the T-bar form an 'L' and the centre can legitimately be in thin air. I've learnt these centres co-incide fully with the entity's actual centre only when the entity is symmetrical in 2 dimensions. ![]() (And z - but I can't grasp 3D's complex, interdependent co-ordinate and work-planes systems. ![]() ![]() I see a drawing as a string of geometrical entities - lines, circles, rectangles etc., and joined sets of them, each with its location designated by an envelops symmetrical about a plotting-centre whose (x,y) co-ordinates are quoted in the Inspector Bar. I've staggered to a point where I can make fairly straightforward, workshop-useable drawings, but I feel I am using the system very inefficiently even for those. ![]()
