计算两个几何对象之间最近的距离可以使用这个函数6 G k* H: A( ~9 `% q2 G4 x$ A
ModelDoc2::ClosestDistance
% |, A2 A Q- c: _) x- M! {! M# G5 Q/ E7 d8 c
retval = ModelDoc2.ClosestDistance ( object1, object2, point1, point2 ) I% [" x+ M% D& N- g, E
8 |* P; T2 T, ]9 G3 y% J( n0 ]+ GInput: (LPDISPATCH) object1 Pointer to first object
3 M* V. B) _4 yInput: (LPDISPATCH) object2 Pointer to second object
# J2 a1 m2 b9 h/ ~3 bOutput: (VARIANT) *point1 Array of x, y, z coordinates for the first point( e8 }/ X4 h- g- S) t8 V8 c/ u2 L
Output: (VARIANT) *point2 Array of x, y, z coordinates for the second point& V2 z/ g9 l& w" e+ R% I2 e
Output: (double) retval Minimum distance; -1.0 if no solution
