Click Extrapolate
.
The Extrapolate Definition dialog box appears. |
-
Select an endpoint on a curve.
-
Select the curve to be Extrapolated (it can be
a wire, an edge, a curve or a line).
-
Select the extrapolation type:
-
Length:
enter the value in the Length field or use the
manipulators in the 3D geometry.
 |
It is
not advised to enter a negative value in the Length
field. |
 |
In Curvature
mode, this length actually is the distance on the tangent
extrapolation at which a plane normal to the curve is located.
This plane is used to split the extrapolated curve. |
-
Up to: the Up to field is
enabled. Select an element belonging to the same support as the
curve to be extrapolated (curve, surface or plane).
 |
The
element must intersect the curve to be extrapolated. |
|
-
Specify Continuity conditions:
|
 |
Length extrapolation in Tangent mode |
|
 |
Length extrapolation in Curvature mode |
|
 |
Up to extrapolation in Tangent mode |
|
If needed and if the initial curve lies on a plane or
surface, you can select this support.
In this case the extrapolated curve lies on the surface too, and is
relimited by the support boundary. |
 |
 |
Extrapolation without support |
Extrapolation with a support |
-
Click OK to create the extrapolated curve.
The curve (identified as Extrapol.xxx) is added to
the specification tree. |
|
 |
Check Assemble result
if you want the extrapolated curve to be assembled with the original
curve. |
