Hi Michael,

Just for the record have managed to record different examples of tangent behavior.

This example is from SolidEdge, it's the tangent circle creation mode.
It's basically a "2pts on edge circle" with a fixed tangent 1rst point, is has a live dragging of the circle.

This one from Autocad, it is a "3pts on edge circle", in this example: tan, point, point.

The reference circle is in white and in the background there is a gray shape to show an example of tracing situation.
This behaves in a different way as the tangent point will change depending on the two points picked afterwards. The results does not show after the 3rd point has been set.

I hope this is not too confusing.

Hi Marc, the first one is similar to the Draw curve / Arc / Cont (continue) tool in MoI.

Except that the MoI arc continue tool is limited right now to only working off the end of an existing curve. So with a circle like you're using there, you will need to split the circle by a line into 2 pieces, then you can use arc continue to come tangent off of the end of one of those pieces.

I think it should be possible for me to tune this up so that it works in more situations, like coming off of a circle like you show there.

The 3pts one is somewhat more difficult to tune up, that one will have to wait until after V1, but thank you for putting up those videos to help me understand!
