How Do You Do an Extrusion in SketchUp?

SketchUp is a powerful 3D modeling software that allows users to create and manipulate various objects. One of the key features of SketchUp is the ability to perform extrusions.

Extrusion is the process of creating a 3D object by stretching a 2D shape along a path. In this tutorial, we will explore how to do an extrusion in SketchUp.

Step 1: Creating a 2D Shape

To begin with, you need to create a 2D shape that will serve as the base for your extrusion. SketchUp offers various tools to draw shapes such as rectangles, circles, polygons, and more. Use the Rectangle Tool or any other appropriate tool to draw your desired shape.

Step 2: Selecting the Shape

Once you have created your shape, use the Select Tool to select it. The selected shape will be highlighted with dotted lines.

Step 3: Activating the Push/Pull Tool

To perform an extrusion, you need to activate the Push/Pull Tool. You can find this tool in the toolbar or by navigating to Tools > Push/Pull. Click on the Push/Pull Tool icon or press ‘P’ on your keyboard to activate it.

Step 4: Extruding the Shape

With the Push/Pull Tool activated, click on the face of your selected shape and start dragging it along the desired direction. As you drag, you will notice that SketchUp automatically displays measurements indicating how far you are extruding.

Tips:

  • Holding down Shift while dragging constrains the extrusion to a specific axis (vertical, horizontal, or diagonal).
  • Entering a specific measurement while dragging allows you to control the exact length of the extrusion.
  • Double-clicking on a face automatically extrudes it to the height of the adjacent face.

Step 5: Completing the Extrusion

Once you have achieved your desired extrusion length, release the mouse button to complete the extrusion. SketchUp will now create a 3D object by stretching your 2D shape along the path you specified.

Step 6: Modifying the Extruded Object

The extruded object can be further modified using various SketchUp tools. You can edit its dimensions, add details, apply materials, and more. Experiment with different tools and techniques to enhance your design.

Congratulations! You have successfully learned how to do an extrusion in SketchUp.

With this technique, you can create complex 3D objects by simply stretching 2D shapes. Keep practicing and exploring SketchUp’s features to unleash your creativity!
