I'm looing for an efficient way to confirm the tangency between a curve and a surface. As tought by @TimF in a previous post, this is key for the success of Thru Curve Mesh.

Below is a simplified model. The four edges of the Green face are all tangent to the neighbouring faces. Now let me try to measure the angle between the highlighted edge and Face_A.

**Method 1**

At first, I simply use "Simple Angle" to measure the angle between the edge and the face. The result "113.3380°" is apparently not what I expect (180°).

**Method 2**

Then I try to do it step by step:

- linear extension of the edge
- project the extended line to Face_A
- linear extension of the projected curve
- measure the angle between the two extend lines

- The result "0.000014°" is OK.

I wonder whether there is a better way to measure the angle between the curve and the face or simply to test their tangency. Thanks!

I tried "Deviation Checking" > "Edge to Face", but was confused about how it works. Official documentation provides very limited information about the command.

Solved! Go to Solution.

Datum Plane, select along edge of green surface. Change location on curve to 100% and cycle orientation on curve to be binormal to path.

Intersect curve between surface a and plane.

measure anglbe between edge and curve.

Hi @StevenVickers Thanks!

Your solution based on binormal plane should be the right method to do the job.

My method based on linear extension and projection should be wrong!
