A complex smooth NURBS surface can be created by tracing NURBS Point Splines over one photographic background image of a side view and adjusting them over another front view image.

The splines were then attached and converted to a NURBS surface. The final step was to use U-Loft to create a smooth surface over the splines.

Using CAD models. You have learned some pluses and minuses of modeling with CAD and importing the models into your 3D Application. To make the process easier, extensive pre-planning between CAD and your 3D Application operators and testing will be helpful.

It is critical to keep the models as efficient as possible and only model what will be seen in the final output.
Simulate geometry when possible. Use the Materials bump, opacity, and wire attributes to create the illusion of complex geometry. Everything is fake, so fake it well.

Use your 3D Application's new Bevel Profile modifier, lofting, and lathing to turn 2D shapes into 3D objects.

Become familiar with all the tools available, and it will be easier to choose the right tool at the appropriate time. n Take advantage of Referenced shapes to loft or lathe into 3D objects. NURBS surfaces and splines can be very resource-intensive. Use them when no other modeling option is appropriate.

Dummy objects combined with the Linked Xform modifier are a powerful tool to simplify the editing of path vertices on a lofted object. The dummies act as large handles to speed production.

For flowing curved objects, your 3D Application's new NURBS features offer a flexible, animatable surface creation tool. Referenced shapes give you a 2D control structure from which to easily edit the 3D object.
