Description
This property allows you to get and set a slope direction at the start point of a spline. This property takes affect only if IMdSpline::SlopeOptionFirst is set to constant.
Syntax
Property get:
Direction = FirstDirection( );
Return: (Variant) Direction
Variant that contains double type one dimensional array of vector coordinates that defines the slope direction at the start point of a spline.
Property set:
FirstDirection( Coordinates );
Input: (Variant) Direction
Variant that contains double type one dimensional array of vector coordinates that defines the slope direction at the start point of a spline.
Note
All coordinates are given relative to the model's main UCS.
