It would be useful to have an additional line tool that could be drawn tangent to an existing circle and perpendicular to a line.

Yep - agree! That would be helpful! ;-)
Thank you!
Fantastic, thanks Andrew.
Great new tool, very useful.
In testing I noticed that if I select the wrong entity - say a circle, arc etc. the feedback in the error message is wrong, to my thinking it should read 'Entity is not a Line'!
See attached screenshot.
Thanks, yes. This has been fixed in:
