Orthographic projection only - I can't draw in 3D, but more importantly, that would not give me the machining information I need.
I still can't see how to fit even two simple rectangles together, line-on-line on the correct alignment, without laborious calculations.
I'm trying to design a small, 2-throw crankshaft with 2 web pairs 90º apart, and various diameters: geometrically, its elevation is a row of various rectangles. The main shaft is along the X-axis, but some rectangles are unsymmetrical with the axis and mating parts. I would like to be able to draw it accurately enough for TC to dimension it from one end for machining - I don't believe I can.
I have advice gratefully received from Henry Hubbich. Summarised, he says:
- "Relocate the Reference Point."
Under "Edit", called "Block/Space" RP. Right... but I don't know if the new RP is on the intended alignment axis, especially where the two parts are mutually unsymmetrical. Also, I assume I do that to both elements, but when selecting the second, the first RP reverts to Centre of Extents (the centre of the rectangle).
-- Drag one object by its new RP to the new position.
I understand that as making the mating parts' new RPs Snap together. Hence my comment about alignment axis. Oh, I can't, as the little yellow RP dots are back home in the middles of the rectangles anyway.
---- "and use a snap that refers to the 'to' point..." (Henry's words).
Which? Many snaps listed, some 3D-only; none "by reference points".
The Snaps section in the Manual is muddled up with that about Layers; but like most of the document, tells me nothing helpful.
So.... is making one side of a polygon lie exactly on another and on the correct axis in two dimensions, without co-ordinate calculations, actually possible? Just be thankful I avoid 3D's rebellious co-ordinates, work-planes and axes!
