Space Curves are 3-Dimension curves in space.

Curve Command

• Using the curve command, users specify curve forms by selecting sequential control points.
• If any control point lies on a different plane (sits at a different Z height) than others, the result is a space curve.

Creating Space Curves

2.5D

• One option for creating a space curve is to draw a planar curve, and then use gumball or move to drag them in space.cur

• This method is sometimes referred to as 2.5D, meaning the user starts with a flat curve, and then "pushes and pulls" it into 3D space.

Freeform Space Curves

• Another method of generating space curves uses existing geometry like curves and points as "anchors" to draw a 3D curve.
• This technique is typically done all in PERSPECTIVE view.

• In this case, end points to a network of straight lines provides the anchors for a space curve.
