Convert 2D drawing to 3D in AUTOCAD 2022| How to draw 3D drawing in Autocad 2022| Techy Things|

Converting a 2D drawing to a 3D model in AutoCAD 2022 involves several steps, including setting up your workspace, converting 2D objects to 3D, and creating 3D models from scratch. Here’s a detailed guide on how to do this:

Step 1: Set Up Your Workspace

1. **Switch to 3D Modeling Workspace**:
  - Open AutoCAD 2022.
  - Click on the gear icon in the bottom-right corner of the window to open the workspace selector.
  - Select "3D Modeling" from the list.

2. **Activate the 3D Tools**:
  - Ensure that the "3D Tools" tab is visible on the ribbon. If not, right-click on the ribbon and select "Show Tabs"  "3D Tools".

Step 2: Convert 2D Drawing to 3D

#### A. *Creating 3D Objects from 2D Shapes*

1. **Open Your 2D Drawing**:
  - Open the drawing that contains your 2D geometry.

2. **Extrude 2D Shapes**:
  - Select the 2D shape (e.g., a rectangle, circle, or polyline) you want to convert to 3D.
  - Go to the "Home" tab and click on the "Extrude" tool in the "Modeling" panel.
  - Specify the height of the extrusion to create a 3D object.
