This task shows you how to edit a curve which
connects two elements of the curve type. |
|
Open the
Edit_Connecting_Curves.CATPart document. |
|
-
Double-click the connecting curve you want to edit.
Red arrows indicating tangency directions are now displayed at each
extremity point.
|
|
|
The Connect Curve Definition dialog box is displayed. For
each support curve, you can edit the following options as appropriate:
- Point: defines the extremity point (on the support curve)
of the connecting curve.
- Curve: defines the support curve for the connecting curve.
- Continuity: indicates whether the connecting curve is
continuous in point, in curvature or in tangency with the support curves.
- Tension: when the connecting curve is continuous in
curvature or in tangency, specifies the tension which is applied to it.
- Reverse Direction: when the connecting curve is continuous
in curvature or in tangency, reverses its direction.
|
|
-
For the first support curve, select Tangency
from the Continuity field and set the tension to 3.
|
|
|
-
To reverse tangency
directions you can now click both red arrows available when editing. This
is equivalent to clicking the Reverse Direction button from
the dialog box. For the purpose of our scenario, click the left arrow.
You must obtain this:
|
-
For the second support curve, click the Point field, then
select another extremity point (CtrlPoint.4 for example).
|
|
-
When you are satisfied with your modifications, click
OK to validate and exit the dialog box.
