Enhancing TechDraw with geometric tolerances and surface finishings

[wandererfan]

What about such symbols?

If I recall correctly, Reox's macro depends on the symbols being available in a font. I could not find a unicode code point for Surface Texture symbol. In any case, that is a compound symbol with various bits of text embedded, so we need a different solution.

For a full implementation, I was thinking along the lines of Svg symbols with EditableText embedded, placed on a LeaderLine somewhat like WeldingSymbol.

Agree. Like the welding symbol.

yes, my implementation uses fonts.
But there is somewhere a welding symbol font, like this one: https://www.fontspace.com/micronus/weldsymbols
(I think somewhere I linked other fonts too - just search in the other threads)

I've created a Wiki page with all the information I found so far:

Please look and tell if I missed anything.

Although a 2D approach is quite user-friendly and easy to implement I think we should strive to define model-based (parametric) tolerances rather than 2D symbols.
