Click Boundary
.
The Boundary Definition dialog box appears. |
 |
-
Use the combo to choose the Propagation type:
- Complete boundary: the selected edge is propagated
around the entire surface boundary.
- Point continuity: the selected edge is propagated
around the surface boundary until a point discontinuity is met.
- Tangent continuity: the selected edge is propagated
around the surface boundary until a tangent discontinuity is met.
- No propagation: no propagation or continuity
condition is imposed, only the selected edge is kept.
|
|
 |
You can select the
propagation type before selecting an edge. |
-
Select a Surface edge.
The boundary curve is displayed according to the
selected propagation type. |

-
You can relimit the boundary curve by means of two
elements.
 |
If you
relimit a closed curve by means of only one element, a point on curve
for instance, the closure vertex will be moved to the relimitation
point, allowing this point to be used by other features. |
-
Click OK to create the boundary curve.
The curve (identified as Boundary.xxx) is added to
the specification tree. |
 |
You cannot
copy/paste a boundary from a document to another. If you wish to
do so, you need to copy/paste the surface first into the second
document then create the boundary. |
About the Propagation Type
|
- If you select the surface directly, the Propagation
type no longer is available, as the complete boundary is
automatically generated.
|
 |
Provided the generated boundary curve is continuous,
you can still select a limiting point to
limit the boundary. |
 |
Using the red arrow, you can then invert the
propagation of the limited
boundary. |
 |
- If you select a curve which has an open
contour, the Propagation type becomes available: choose the No
Propagation type and select the curve again. The extremum
points will define the boundary result.
