How to Switch to 3D Modeling in AutoCAD Quickly

To switch to 3D modeling in AutoCAD, change your workspace to 3D Modeling using the workspace switcher at the bottom-right corner or the WORKSPACE command. Then use 3D tools like EXTRUDE, REVOLVE, and 3DORBIT to create and view 3D objects.

Syntax

Switching to 3D modeling involves changing the workspace and using 3D commands:

• WORKSPACE - Command to switch workspace.
• EXTRUDE - Converts 2D shapes into 3D solids by extending them.
• REVOLVE - Creates 3D solids by revolving 2D profiles around an axis.
• 3DORBIT - Allows rotating the view to see the model in 3D.

autocad

WORKSPACE "3D Modeling"
EXTRUDE <2D object>
REVOLVE <2D object> <axis>
3DORBIT

Output

Workspace changes to 3D Modeling; 2D shapes become 3D solids; view rotates freely in 3D space.

Example

This example shows how to switch workspace and create a simple 3D box from a 2D rectangle.

autocad

WORKSPACE "3D Modeling"
RECTANGLE 0,0 10,5
EXTRUDE (select rectangle) 8
3DORBIT

Output

Workspace set to 3D Modeling; rectangle drawn; rectangle extruded to 8 units height forming a box; 3D orbit activated for viewing.

Common Pitfalls

Common mistakes when switching to 3D modeling include:

• Not switching the workspace, so 3D tools are hidden.
• Trying to extrude without selecting a closed 2D shape.
• Forgetting to use 3DORBIT to view the model from different angles.
• Using 2D commands only, which do not create 3D objects.

autocad

/* Wrong: Trying to extrude an open line */
EXTRUDE (select open line) 5

/* Right: Use a closed shape like rectangle or circle */
RECTANGLE 0,0 5,5
EXTRUDE (select rectangle) 5

Output

Error or no extrusion for open line; successful extrusion for rectangle creating a 3D box.

Quick Reference

Command	Purpose
WORKSPACE "3D Modeling"	Switch workspace to 3D tools
EXTRUDE	Create 3D solids by extending 2D shapes
REVOLVE	Create solids by revolving profiles
3DORBIT	Rotate view to see 3D model
BOX	Create a 3D box directly
SPHERE	Create a 3D sphere
PRESSPULL	Push or pull faces to add/remove volume

Key Takeaways

Switch your workspace to '3D Modeling' to access 3D tools easily.

Use closed 2D shapes and commands like EXTRUDE to create 3D solids.

Use 3DORBIT to view and navigate your model in three dimensions.

Avoid using 2D commands alone when working in 3D space.

Practice with simple shapes like boxes and cylinders to get comfortable.
