This task shows you how to create a drop-off. This drop-off can
complete a Solid From Zones
if it is incomplete or inaccurate or be used for designing purposes.
A drop-off can be defined by:
- a drop-off curve and a slope angle and a height.
- The drop-off curve is the reference curve driving the drop-off.
It must be parallel to the reference surface.
This curve is the top or the bottom of the ramp, if identified.
- The slope is the angle or drop-off ratio (e.g. 1:20) of the ramp with
respect to the reference surface.
- The height is the height of the bottom curve. This parameter is
associated with the slope to create the bottom curve.
- or a drop-off curve and a bottom curve.
In this case, Slope and Height are not required.
- a ply border: if the top drop-off curve does not exist, you must identify a
ply border that will drive the drop-off. As a consequence an offset of
(thickness at top – thickness at geometrical level x) is required as
input as well as Slope and Height to compute the whole
ramp from top to bottom.
If necessary, you can modify the limits of the drop-off:
- Start/End limits of drop-off curve: allow an
extrapolation of the drop-off curve in order to generate a greater
surface
- Left/Right limits: allow to re-limit the ramp
surface in width and
to position it along its width (particularly valued to a
tolerance to avoid gaps while intersecting the ramp with the context
surfaces)
