The following 3D sketch commands create curve geometry using specified values, or by projecting geometry:
- Helical Curve creates a 3D coil from parameters.
- Equation Curve creates a 3D curve from equations.
- Intersection Curve creates a 3D curve from intersecting geometry.
- Silhouette Curve creates a 3D curve at the outer boundary of a surface.
- Project to Surface creates a 3D curve by projecting selected geometry to a 3D face.
- Include Geometry creates a 3D curve by copying existing edge geometry.
