B-spline and 3D dialog box

Used to control specific attributes of B-splines and 3D elements being placed in the design. Opens when B-spline and 3D is chosen from the Element menu.

Tolerance

Sets the Active Tolerance, in working units, for B-spline tools. The default is 0:0 1/8.

When the Place B-spline Curve tool is used with the Least Squares Method, the error distance between data points and the curve are reported if they exceed the Tolerance.
This setting supplies the default tolerance for B-spline modification demands. This default tolerance can be overridden by each command.

B-spline Control Polygon

Contains controls that are used to set attributes that are specific to the display of B-spline curves in addition to controls to set attributes, in the U and V directions, that are specific to the display of B-spline surfaces.

Curve Polygon

Controls whether control polygons of B-spline curves are Visible or Invisible when placed.

Key-in: ACTIVE BSPLINE POLYGON <OFF | ON | TOGGLE>

Curve Display

Controls whether B-spline curves are Visible or Invisible when placed.

Surface Polygon

Controls whether control nets of B-spline surfaces are Visible or Invisible when placed.

Surface Display

Controls whether B-spline surfaces are Visible or Invisible when placed.

Surface/Solid Iso Lines

Sets the number of rule lines in the U and V directions upon placement.

U Rules

Sets the number of rule lines in the U direction upon placement.

Key-in: ACTIVE BSPLINE URULES [rule_lines]

V Rules

Sets the number of rule lines in the V direction upon placement.

Key-in: ACTIVE BSPLINE VRULES [rule_lines]

Surface/Solid As Cell Type

Contains controls for setting the method of display for SmartSolids.

Display Mode

Sets the method of display for SmartSolids.

Wireframe

Surfaces

Suppress Rule Lines

Contains settings that control the display of iso-lines on B-spline and Complex Blending faces.

B-spline Faces

If on, displays a fewer number of iso-lines than specified in the Surface/Solid Iso Lines fields. The exact number used depends on the curvature of the B-spline face.

Complex Blending Faces

If on, displays a fewer number of iso-lines than specified in the Surface/Solid Iso Lines fields. The exact number used in the program depends on the curvature of the Complex Blending faces. It is recommended that you turn on this toggle.
