Composite Curve Trajectory Function
The trajectory parameter of a composite curve, trajpar_of_pnt, can be used in relations.
The following function returns a value between 0.0 and 1.0:
trajpar_of_pnt("trajname", "pointname")
where:
trajname—the name of a composite curve.
pointname—the name of a datum point.
The trajectory is a parameter along the composite curve at which the plane, normal to the tangent of the curve, passes through the datum point. The datum point does not have to be located on the curve—the parameter is calculated at the point on the curve that is closest to the datum point.
If the composite curve is used as the spine of a multitrajectory sweep, then trajpar_of_pnt either agrees with the parameter trajpar at this plane, or else with 1.0 – trajpar (depending on your choice of the starting point for the sweep feature).作者: vigor 时间: 2004-5-13 08:54
itos(int)
Converts integers to strings. Here, int can be a number or an expression. Nonintegers are rounded off. 作者: grandness 时间: 2004-5-17 10:14
