It is possible to edit the feature reference elements by
first selecting a curve in the dialog box list then choosing a button to
- Remove the selected curve
- Replace the selected curve by another curve.
- Add another curve.
By default, the application computes a
spine, but if you wish to impose a curve as the spine to be used, you
just need to click the Spine tab then the Spine field and select the
spine of your choice in the geometry.
In the Spine tab page, you can select the
Spine check box to use a spine that is automatically computed or
select a curve to impose that curve as the spine.
Several coupling types are available in the Coupling
- Ratio: the curves are coupled according to the
curvilinear abscissa ratio.
- Tangency: the curves are coupled according to their
tangency discontinuity points. If they do not have the same number
of points, they cannot be coupled using this option.
- Tangency then curvature: the curves are coupled
according to their curvature discontinuity points. If they do not
have the same number of points, they cannot be coupled using this
- Vertices: the curves are coupled according to their
vertices. If they do not have the same number of vertices, they
cannot be coupled using this option.
The Relimitation tab lets you specify the
removed multi-sections solid relimitation type. You can choose to limit
the feature only on the Start section, only on the End
section, on both, or on none.
In the Smooth parameters section, you can
- the Angular Correction option to smooth the lofting
motion along the reference guide curves. This may be necessary when
small discontinuities are detected with regards to the spine
tangency or the reference guide curves' normal. The smoothing is
done for any discontinuity which angular deviation is smaller than
0.5 degree, and therefore helps generating better quality for the
resulting multi-sections solid.
- the Deviation option to smooth the lofting motion by
deviating from the guide curves.
If you are using both Angular Correction and
Deviation parameters, it is not guaranteed that the spine
plane be kept within the given tolerance area. The spine may first be
approximated within this deviation tolerance, then each moving plane may
rotate within the angular correction tolerance.
