That is a not a very accurate way of creating a tangential line.
(SOLVED) Can you set (increase) the calculation accuracy of freecad?

At the moment, No.
Finding the tangent at a point on a curve is possible, we have the tangentAt method for that. But finding the tangent on a curve that passes through a given ('from') point is a different matter. Programming a solution for circles would obviously be doable, but for other curves I would not know of a direct method. An 'indirect' method would be to test multiple solutions and then accept the 1st solution within an acceptable tolerance.

Thanks for the feedback. I suspect that it will soon be possible in the sketcher.

Didn't you ask this quite recently with another spring?

Yes, I started a challenge.
https://forum.freecadweb.org/viewtopic. ... 19#p628719
when trying to create solutions, i came across the question why draft sometimes does not produce an intersection at a tangent. (this thread).
one suggested solution didn't work, which is why i used the spiral here as an example

I know you are
Remember the discussion.
But others probably aren't.
Cheers,

That's not what I meant. I thought of this https://forum.freecadweb.org/viewtopic.php?f=3&t=70290, where you got quite some good answers. So why start it all over again? Did I miss something?

Yes, sorry, I forgot about that. but this additional information came from roy_043.
in the end it was worth it
