You can create a 3D curve offset from a reference curve.
Before you begin: Create a 3D shape containing a curve.
From the section of the
action bar, click 3D Curve Offset.
In the Curve box, select the reference curve to be offset.
Warning:
The reference curve must be tangency continuous and must
not be collinear to the offset direction.
In the Pulling direction box, select the offset direction.
Note:
To reverse the pulling direction, click .
A direction arrow appears in the 3D geometry and lets you change the direction.
Important:
The pulling direction corresponds to a draft direction.
It does not correspond to the direction of the 3D curve. If you select a
plane as the pulling direction, the latter is normal to the plane.
In the Offset box, specify the offset value or use the
arrows to change the value.
Click Preview to see the offset curve.
Click OK.
The curve (identified as 3D curve
offset.xxx) is added to the tree.
Radius = 20 mm and Tension = 1 Radius = 5 mm and Tension = 1 Radius = 20 mm and Tension = 2 Radius = 20 mm and Tension = 0.3 Closed curve
Important:
3D corner parameters enable to manage singularities:
Radius: if the curvature radius of the input
curve is smaller than the offset value, 3D corner curves are created
to fill the holes
