Two D To Three D Curve

Insert Curve 3D from 2D Curves

The 3D Curve from 2D Curves command creates a 3D curve from two plane curves lying in different planes, based on the projection of the 2D curves.

First of all you will have to select the two curves: 1st Planar Curve and 2nd Planar Curve.

If the projection of one of the two curves is a line, it does not identify a single plane. In that case, a warning message is displayed. You must specify the projection direction, using the Direction drop-down list that shows up in the selection list.

Note
When the selected curve is a line, the direction to be selected must be the normal to one of the plane containing the line. If it is not, an appropriate warning is displayed.

The Associative Mode check box enables you to create curves which retain a link to the surfaces/curves they derive from.

When the check box is selected, the resulting curves will be associative. The new curve will retain a link to the entities it derives from. A specific node displaying both the original entities and the resulting associative curve will be added to the Model Structure.
If you select non-associative entities (such as non-associative surface borders or non-associative curves), a message will be displayed to inform you that you have selected non-associative entities, which will become the root of the structure.
When the check box is cleared, the resulting curves will not be associative.

Furthermore, an additional option is now available under More Options: High quality approximation.

When the check box is selected, the resulting curves will be G3 or G4 continuous and will have higher degree.
When the check box is cleared, the resulting curves will have degree 3 and continuity 2.
