3D Modeling Tab (Options Dialog Box)

Sets options for working with solids and surfaces in 3D.

List of Options

The following options are displayed.

3D Crosshairs

Controls settings for the display style of the crosshairs pointer in 3D operations.

Show Z Axis in Crosshairs

Controls whether the Z axis is displayed by the crosshairs pointer.

Label Axes in Standard Crosshairs

Controls whether axis labels are displayed with the crosshairs pointer.

Show Labels for Dynamic UCS

Displays axis labels on the crosshairs pointer for the dynamic UCS even when the axis labels are turned off in the Label Axes in Standard Crosshairs box.

Crosshair Labels

Choose the labels to display with the crosshairs pointer.

Use X, Y, Z

Labels the axes X, Y, and Z.

Use N, E, z

Labels the axes with abbreviations for North, East, and Z elevation.

Use Custom Labels

Labels the axes with characters that you specify.

Display Tools in Viewport

Controls the display of the ViewCube, the UCS icon, and the viewport controls.

Display the ViewCube

Controls the display of the ViewCube.

Display the UCS icon

Controls the display of the UCS Icon.

Display the Viewport Controls

Controls the display of the viewport control menus for viewport tools, views, and visual styles that are located in the upper-left corner of every viewport.

3D Objects

Controls the settings for the display of 3D solids, surfaces, and meshes.

Visual Style While Creating 3D Objects

Sets the visual style that is displayed while creating 3D solid and mesh primitives and extruded solids, surfaces, and meshes. (DRAGVS system variable)

Deletion Control While Creating 3D Objects

Controls whether geometry used to create other objects is retained or deleted. (DELOBJ system variable)

Isolines on Surfaces and Meshes

Sets the surface density for PEDIT Smooth in the M direction and the U isolines density on surface objects. (SURFU system variable)

Sets the surface density for PEDIT Smooth in the N direction and the V isolines density on surface objects. (SURFV system variable)

Maximum Point Cloud Points Per Drawing (Legacy)

Sets the maximum number of points that can be displayed for all point clouds attached to legacy, pre-2015 drawings (POINTCLOUDPOINTMAX system variable).

For 64-bit systems, the maximum number of points is 25 million. Increase the limit to improve visual fidelity for the point clouds. Lower the limit to improve system performance.

This setting cannot be changed for 32-bit systems (x86), which have a maximum of 1.5 million points.

Tessellation

Opens the Mesh Tessellation Options dialog box, where you can specify settings to be applied to objects that are converted to mesh objects with MESHSMOOTH.

Mesh Primitives

Opens the Mesh Primitive Options dialog box, where you can specify settings to be applied to new mesh primitive objects.

Surface Analysis

Opens the Analysis Options dialog box, where you can set options for zebra, curvature, and draft analysis.

3D Navigation

Sets walk, fly, and animation options for displaying 3D models.

Reverse Mouse Wheel Zoom

Toggles the direction of transparent zoom operations when you scroll the middle mouse wheel. (ZOOMWHEEL system variable)

Walk and Fly

Displays the Walk and Fly Settings dialog box.

Animation

Displays the Animation Settings dialog box.

ViewCube

Displays the ViewCube Settings dialog box.

SteeringWheel

Displays the SteeringWheel Settings dialog box.

Dynamic Input

Controls the display of dynamic input fields for coordinate entry.

Show Z Field for Pointer Input

Displays a field for the Z coordinate when using dynamic input.
