Full Version: Incorrect TAN snaping

I apologize, I couldn't attach the video.

As you can see in the video, I'm trying to snap a curved line at an angle to the circle. I can't do this because the snap only considers the tangent of the curve, which causes unnecessary intersections between curves.

I originally thought that's how the Tan/Tan snapping was supposed to work.

Is there any way to fix this, or a method that will align the curves on a tangent with one single intersection?

Hi Moi3dFan, both single Tan and also Tan/Tan snapping work on 2 points like when you are drawing a line.

The single Tan snaps the 2nd point of the line onto a curve where the curve tangent passes through the first point.

Tan/Tan snapping snaps both the 2nd point of the line and also repositions the 1st point of the line onto curves where there is a line of shared tangency between the 2 curves.

Both of these affect 2 picked points, they don't involve the geometry of the object you are dragging.

You can get the result you want though by using a perp/perp construction line, see these video examples:

And another method - first place the object at the center of the circle and then you can use Transform > Move with a perp snap onto the circle like this:
