How to use extrude command to create 3D objects

The EXTRUDE command is used to create 3D solid or surface by extruding the dimension of a selected object.

For example, a circle can become a cylinder, a line can become a 3D plane, and a rectangle can become a box.

How to access EXTRUDE command?

• When using 2D Drafting workspace, find 3D tab> Modelling panel > Extrude, as shown in the following picture,

• When using GstarCAD Classic workspace, find Draw > Modeling > Extrude, shown as below,

• Or just enter command EXTRUDE, shown as below,

A step-by-step tutorial to turn a circle into a cylinder

1. Create a random circle in 2 dimension, as shown in the following picture,

2. When it comes to creating 3D objects, we’ll need the Z-axis, so enter 3DO and press Enter key,

3. Now we can see this circle in 3 dimensional perspective, as shown in the following picture,

4. Execute the EXTRUDE command, and select objects to extrude, shown as below,

5. Select the circle, and specify height of extrusion, as shown in the following picture,
