If the spacing between the rails changes, the section scales or stretches. When on, cross-section curves are translated and scaled so they intersect both rails.

Accept cookies and close this message. However, understand that the more dependencies a model has, the slower interactive performance becomes. 3ds max nurbs modeling tutorial curves, the “rails,” define the two edges of the surface.

When you release the mouse button, the surface reappears. To see the entire surface and the curve or curves on it projected into a flat plane, use Edit Curve. Click to turn on Edit Curve. Click to turn on Insert, then click the curve. As you drag the mouse over the surface, the available section curves are highlighted. Sweep surfaces are constructed from curves. You 3ds max nurbs modeling tutorial use Refine or Make First, for example, without changing levels.

2-Rail Sweep Surface

Remember that without leaving the viewport, you can right-click to display a quad menu with shortcuts for changing the sub-object level, creating some sub-objects, and using some other edit commands. On the Curve Common rollout, the controls Reverse and Make First let you control the direction of the curve, and where its 3ds max nurbs modeling tutorial point or CV is located.

You can’t blend from a trimmed edge. The other curves nurba the surface’s nurrbs sections.

Snapping CVs to each other doesn’t always succeed, because of rounding off. For example, minimizing the Modifiers rollout helps unless 3ds max nurbs modeling tutorial applying Modifiers, and minimizing the Surface Common rollout is useful when ,ax creating U loft, UV loft, and 1-rail or 2-rail sweep surfaces.

Go to the Modify panel. While creating curves, you can turn on the Draw in All Viewports toggle.

A good rule of thumb is to start with Spatial approximation and an Edge value of Also, remember that snaps work in a viewport only when you have made the viewport active. The cross sections in the middle are translated 3ds max nurbs modeling tutorial touch the rails at nyrbs closest point to the ends of the cross-section curves.

Justin has also had numerous articles, tutorials and images published in 3D World and 3D Artist. Click the curves in the appropriate order 3ds max nurbs modeling tutorial the sweep. The order in which you click the curves can affect the shape of the sweep surface.

Adjusting tension changes the flatness or “bulginess” of that end of the blend. The Edit Curve button lets you directly transform the CVs of a curve within a U loft or UV loftwithout changing the sub-object level.

Use the Displace NURBS world space modifier to convert the displacement map into an actual displaced mesh so you can see the effect of displacement in viewports.

In general, point curves and surfaces are slower than CV curves and surfaces. Viewports display the selected curve in blue.

For the best possible experience on our website, please accept cookies. This list shows the names of the cross-section curves, in the order you click them. Trims are the slowest kind of dependency, and texture surfaces are the slowest 3ds max nurbs modeling tutorial of dependent sub-object. This removes the modifiers from the stack without changing the position of the modified points or CVs, making for a simpler and quicker model. As you move the mouse over a curve that is not part of the active NURBS object, the cursor changes shape to indicate that 3ds max nurbs modeling tutorial can pick the tutoria, but the curve is not highlighted in blue.

You can select a curve by clicking its name in the list.

Click the curve to nubrs as the first rail, then click the curve to use as the second rail. A 2-rail sweep surface is similar to a 1-rail sweep.
