This method gets a point that lies on a given face that is closest to a given point and also returns a normal to a face from a received point on a face.
Cimatron 2024 or later
double[] ClosestPoint(double[] inPoint);
def ClosestPoint(inPoint System.Double[]) -> double[]
|
Return: double[] |
oPointOnSurface_Normal—Variant that contains a double type one-dimensional array of six elements. The first three elements are normal vector coordinates to the face formed by the received closest point, and the second three elements are coordinates of the closest point on the face. |
|
Input: double[] |
inPoint—Variant that contains a double-type one-dimensional array of given point coordinates. |
All coordinates are given relative to the model's main UCS.
