Tangential Curve Through 2 Points

[John_Tweasers]

Hello.

I have come across a problem that I cannot solve.
I need to generate a curve that is tangental to both the red lines shown.

However it needs to run through both points in a continuous curve (Curve Through Control Pts doesn’t work)

Any ideas?

Thanks

Does this look right?

Thanks for getting back to me.

Unfortunately not, It needs to be a smooth continuous curve (like in this screenshot)
This is the closest I’ve managed to come.

Thanks!

Ok, thanks for the clarification

Something like this?
You won’t get the blend curve go through the points precisely, but some fiddling with the control points and the start points will get you reasonably close…

Three blend curves (the first two with the Point option) and History might allow you to get there with some edits to the blends:

This problem is similar to Blending two curves (Tangency on both ends) through a point

_InterpCrv 's _StartTangent and _EndTangent options are available when _Degree=3 and _SubDFriendly=No.
