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!
