||This task shows you how to perform a
Digitized Morphing using a Limit Curve:
when using a displacement
map to alter a die face development, you may have to limit the change to
take place within the punch opening outline. As the displacement map
encompasses a larger area, a Limit Curve to control what portion of the
die face will be altered.
||The shape to deform is
in the samples directory.
The file of vectors used to compute the
DeformationVectors01.txt in the samples directory.
Please refer to Digitized Morphing for more
information on the general operating mode.
||For a better result, the points in
the displacement file should be inside the area defined by the limit curve,
and the vectors should be consistent with the limit curve: the vectors
associated to points that
are near to the limit curve should have a small magnitude.
Click the Digitized Morphing icon
The Digitized Morphing dialog box is displayed:
Select Surface.1 as the
Element to deform.
In the Deformation Element tab, click the
icon and select
DeformationVectors01.txt from the samples directory.
Go to the Limit Element tab and select Sketch.1 as the Limit Curve.
You can select only one curve, open or closed, as the Limit Curve.
It must lie on the surface to deform, and divide this surface in two
If you select a Limit Curve, you can process only one element
The name of the Limit Curve is displayed in the Limit
A contextual menu is available to clear the selection.
Continuity lets you define the type of
continuity between the output surface and the Limit Curve (Point
Once the Element to deform and the Limit Curve are
selected, the area to deform is highlighted. Other Side
lets you process the area located on the other side of the Limit
Curve. The highlight is updated accordingly.
Radius lets you define the radius of a circular pipe centered
on the limit curve, within which points are removed.
This radius is visualized as a dark blue sphere (we set it to 2).
Click Preview. Note that it can take some time.
If the displacement implies a large distortion on the shape, a message is
displayed and the corresponding vectors are highlighted.
You can modify the Pts to ignore value in the Parameters tab to
eliminate these points from the computation (we set it to 10).
Click Preview again.
Click OK when you are done.
