There does not appear to be a way to add geometric tolerances to drawings.
No drawing is complete without this essential defining information. Not only is there no tool to add tolerances for flatness, concentricity, perpendicularity and other basic drawing specs but if you copy and paste the unicode characters for the standard necessary symbols into a drawing note they do not show up on the drawing.
But in this case it does not end here (with dimensional tolerances) - then we’ll need geometric tolerances as stated by @16ohm and therefor also datums they refer to…
… and symbols for surface-finish, maybe weld-symbols…
… not to mention section-views, detail-views, view-breaks…
The drawing-functionality holds a lot of work for the Shapr3D-Team.
