Using this record the inclination of a line between two given curves is calculated. The points on the curves are calculated by intersecting them with a plane which is displaced a given distance along a given axis from the intersection point between the curves.
The direction of the line is from CURVE1 to CURVE2.
This record is supposed to be used in the following situation:
Suppose that two curves intersect each other at a narrow angle and the curves are used to define a surface. To get a "smooth" corner of the surface, the inclination curves along the bounding curves must be correct. These angles can be calculated here.
The resulting angle will be defined in the following planes depending on AXIS:
|
|
AXIS=1: plane y-z |
|
AXIS=2: plane x-z |
|
|
AXIS=3: plane x-y |
The picture below illustrates the usage of the record:
Figure 2:1. The picture above shows the use of record type 16, resulting in an angle in the frame plane:

DELTA |
Distance with sign along AXIS from the intersection point where the inclination (angle) shall be calculated. DELTA is normally supposed to be a small value (typically in the range 0.1-1 mm). |
