You can create several types of 3D curves by using these methods:
| Project Curve |
From a sketch projected to a model face or surface, or from sketched lines on intersecting planes |
| Composite Curve |
From a combination of curves, sketch geometry, and model edges |
| Helix and Spiral |
By specifying a circular sketch, pitch, number of revolutions, and height |
| Split Line |
From a sketch projected to planar or curved (silhouette) faces |
| Curve Through Reference Points |
From user-defined points or existing vertices |
| Curve Through XYZ Points |
From a list of X,Y, Z coordinates for points |
You can then use the curves to create solid model features. For example, you can use a curve as the path or guide curve for a sweep feature, as the guide curve for a loft feature, as a parting line for a draft feature, and so on.
