FaceData.SetNormalVectors Method

Description

Sets normal to be the array of face normal vectors used by the FaceData object. The array must have exactly the same number of elements as there are faces in the mesh or shell it is used with. The array elements specify the normal vectors of the mesh or shell faces--the first array element specifies the normal vector for the first face, the second element for the second face, etc.

The caller of this function is responsible for allocating and de-allocating the memory for the array. This function accepts a pointer to the array and then uses the array directly--it does not make a copy of the array.

Warning Prematurely freeing or deleting the array passed into this function terminates AutoCAD.
