Gap between a Curve and a Surface(Angle)

[Gap between a Curve and a Surface(Angle)] command evaluates the folding angle at boundary point of a curve and a surface. First, find the shortest deviation points of a curves end point and an edge of the surface. Then evaluates the angle between the curve tangent vector and the surface normal vector.

Gap between a Curve and a Surface(Angle)

Step 1

For the prompt"Specify a curve.", select a curve element to measure.

Step 2

For the prompt "Specify a surface", select a surface element to measure.

When selection is done, evaluation will be done. The evaluation result will be shown in the output window. Each line means:

Position on curve

Evaluated point on the curve.

Position on surface

Evaluated point on the surface.

Deviation

The above 2 points distance.

Curve Direction

Curve tangent vector at the position on the curve.

Surface Normal

Normal vector at the position on the surface.

Angle

The angles of the above two vectors.

Vector product

Vector product of the above two vectors.
