This task shows you how to adjust the weight applied to edges or
vertices in order to attract the surface by the mesh. |
|
Open the
ModifySurface5.CATPart
document. |
|
Here is the initial shape: |
|
|
|
-
Click Modification
.
-
Click Attraction
.
Two icons appear in the toolbar, letting you: |
-
define sharp attributes of the selected edge (value indicated with
a minus sign) that are discontinuous in tangency and curvature
|
-
define
smooth attributes of the selected edge that are continuous in
tangency and curvature
|
|
These options are not available if you select
vertices. |
|
If an edge or a vertex already has a weight
value, the look of the edge or the vertex is different from the other
edges or vertices: the edge is thicker, the line is not dotted, and
the vertex is represented by a bigger circle. |
-
Select the element to modify.
The value of the weight, comprised between 0 and 100, is
displayed on the right of the screen. |
-
Hold the left mouse-button and move the mouse to reach
the desired value.
-
Release the left-mouse button when you are satisfied with
the new position of the surface.

Weight on edges using the sharp mode |
|
Weight on edges using the smooth mode |

Weight on vertices |

|
- If you select edges
with different weights, the slider value corresponds to the average
weight of the selected edges. If you modify the mode (smooth or
sharp), the average weight is applied to all the selected edges.
