DWG/DXF Import: Spline Rendering Panel
 
 
 
Bottom of the Page

Application menu Import AutoCAD Drawing (*.DWG, *.DXF) Spline Rendering panel

The Spline Rendering panel of the Import Options dialog lets you determine how spline objects imported from DWG and DXF files are displayed in the viewports and how they're treated by the 3ds Max renderer.

Interface

Spline Rendering panel

The controls on this panel are identical in name and operation to those found on the Rendering rollout of editable spline and Edit Spline objects. The values of these settings apply to all imported shapes. Once the import is complete, you can change the settings as necessary for each object with the Modify panel controls.

Enable In Renderer

When on, the shape is rendered as a 3D mesh using the Radial or Rectangular parameters set for Renderer.

Enable In Viewport

When on, the shape is displayed in the viewport as a 3D mesh using the Radial or Rectangular parameters set for Renderer.

Use Viewport settings

Lets you set different rendering parameters, and displays the mesh generated by the Viewport settings. Available only when Enable in Viewport is turned on.

Generate Mapping Coords

Turn this on to apply mapping coordinates. Default=off.

3ds Max generates the mapping coordinates in the U and V dimensions. The U coordinate wraps once around the spline; the V coordinate is mapped once along its length. Tiling is achieved using the Tiling parameters in the applied material. For more information, see Mapping Coordinates.

Real-World Map Size

Controls the scaling method used for texture mapped materials that are applied to the object. The scaling values are controlled by the Use Real-World Scale settings found in the applied material's Coordinates rollout. Default=on.

Auto Smooth

If Auto Smooth is turned on, the spline is automatically smoothed using the threshold specified by the Threshold setting below it. Auto Smooth sets the smoothing based on the angle between spline segments. Any two adjacent segments are put in the same smoothing group if the angle between them is less than the threshold angle.

Threshold

Specifies the threshold angle for smoothing, in degrees. Any two adjacent spline segments are put in the same smoothing group if the angle between them is less than the threshold angle.

Viewport

Choose this to specify Radial or Rectangular parameters for the shape as it will display in the viewport. Available only when Enable in Viewport and Use Viewport Settings are on.

Renderer

Choose this to specify Radial or Rectangular parameters for the shape as it will display when rendered or viewed in the viewport when Enable in Viewport is turned on.

Radial

Displays the 3D mesh as a cylindrical object.

Thickness

Specifies the diameter of the viewport or rendered spline mesh. Default=1.0. Range=0.0 to 100,000,000.0.

Splines rendered at thickness of 1.0 and 5.0, respectively

Sides

Sets the number of sides (or facets) for the spline mesh n the viewport or renderer. For example, a value of 4 results in a square cross section.

Angle

Adjusts the rotational position of the cross-section in the viewport or renderer. For example, if the spline mesh has a square cross section you can use Angle to position a "flat" side down.

Rectangular

Displays the spline's mesh shape as a rectangle.

Length

Specifies the size of the cross–section along the local Y axis.

Width

Specifies the size of the cross–section along the local X axis.

Angle

Adjusts the rotational position of the cross-section in the viewport or renderer. For example, if you have a square cross-section you can use Angle to position a "flat" side down.

Aspect

Sets the aspect ratio for rectangular cross-sections. The Lock check box lets you lock the aspect ratio. When Lock is turned on, Width is locked to Length that results in a constant ratio of Width to Length.
