Lofting Basics

While lofting is a very versatile modeling tool, you need to keep in mind several things as you begin to loft on your own projects:

  • A loft object can have only one continuous closed or open 2D spline as a path.

  • A loft object can have an unlimited number of open or closed shapes as cross sections, but each shape on a path must have the same number of splines. For example, you cannot loft a circle that has one spline and a donut primitive, which is a compound shape with two splines, on the same loft path.

  • Each shape or path can have an unlimited number of vertices, but they should be kept at a minimum for efficient models.

  • The pivot point position and the Local reference coordinate system of paths and shapes are important in the alignment of the shapes to the path. (See the lofting section in Chapter 2 for more information on alignment.) Figure 5.2 shows a lofting example.
