[3Ds Max] Simple use of the extrusion command (realize 2D to 3D)

Introduction

In 3ds Max, "Extrude" (Extrude) is a common modeling operation used to create solid geometry on a plane or surface. Here are the basic steps to use the Extrude command in 3ds Max:

1. Create basic geometric shapes: Create a basic geometric shape in 3ds Max, such as a polygon or curve. You can use the polygonal modeling tool to create a planar polygon, or the Line Segment tool to create a curved line.

2. Select Face or Edge to Extrude: Select the face or edge you want to extrude. In edit mode, you can use the Selection Tool to select these faces or edges.

3. Activate the extrude command: In the main menu or toolbar of 3ds Max, select the "Edit" > "Extrude" command. Alternatively, you can also use the shortcut "Ctrl + E" to activate the Extrude command.

4. Set extrusion parameters: In the Extrude dialog you can set the following parameters:

   • Amount: This is the distance you want to extrude the face or edge. Can be adjusted by entering a value or using the slider.
   • Chamfer: Whether the extruded edge should be chamfered to smoothly connect to the original geometry.
   • Segments: You can set the number of segments of the extruded geometry to control how smooth it is.
   • Rotation: You can apply a rotation to the extruded geometry if desired.

5. Preview the extrusion effect: preview the extrusion effect in the dialog box, and adjust the parameters as needed until the effect you want is achieved.

6. Apply Extrusion: After clicking the "OK" button, 3ds Max will apply the extrusion effect to the selected face or edge, thus creating a solid geometric shape.

7. Editing Extrusion: After extrusion, you can still adjust extrusion parameters by selecting the extrusion object and reopening the extrusion dialog.

Note that the above steps are based on the basic extrusion functionality of 3ds Max. In practice, there are other advanced options and tools for more complex extrusion operations. It is recommended that you consult the official documentation or tutorial resources for more details on the Extrude command in 3ds Max.

 

Practical example

1. For example, first create a rectangular spline here

 2. Find "Extrusion" in the list of modifiers

 The thickness of the extrusion can be set here

The number of segments in the thickness direction can be set

You can set whether to seal at the beginning and end

 3. If we want to create the effect that a cylinder is dug out from the middle of a block, we can do the following:

First, draw a rectangular wireframe

Uncheck Start a new graph, which means that the next drawn line and the previously drawn line are on the same object

 Create another circular line
