How Do You Extrude a Curve in Sketchup?

Extruding a curve in Sketchup can be a powerful tool to create complex 3D shapes. Whether you want to add depth to a simple line or give dimension to a complex curve, Sketchup offers various techniques to achieve this effect. In this tutorial, we will explore the step-by-step process of extruding curves in Sketchup, so let’s dive right in!

What is Extrusion?

Extrusion is the process of extending or projecting a 2D shape into three dimensions. It involves creating a solid object by adding depth to an existing shape. In Sketchup, extrusion allows you to transform flat curves into 3D surfaces, giving your designs more depth and realism.

Step 1: Drawing the Curve

To begin, open Sketchup and create a new project or open an existing one. Start by drawing the curve you want to extrude using the Line tool or any other relevant tool based on your design requirements.

Note: Make sure that the curve is closed or forms a closed loop for successful extrusion.

Step 2: Selecting the Curve

Select the curve by clicking on it using the Select tool (arrow icon) from the toolbar or by pressing the “Space” bar on your keyboard.

Step 3: Activating the Push/Pull Tool

To initiate the extrusion process, activate the Push/Pull tool from the toolbar or use its shortcut key “P”. The Push/Pull tool looks like an arrow pointing upwards with a square base.

Step 4: Extruding the Curve

Note: Before proceeding with this step, ensure that you are selecting the curve and not any other object or surface.

Click on the selected curve with the Push/Pull tool. Sketchup will create a preview of the extruded surface, indicated by a transparent 3D shape extending from the curve.

Drag your mouse upwards or downwards to adjust the height or depth of the extrusion. You can also type in specific values for precision.

Step 5: Finalizing the Extrusion

To finalize the extrusion, click once again to set the height or depth of your desired shape. Sketchup will convert the transparent preview into a solid 3D surface based on your specifications.

Note: If you want to undo or modify your extrusion, you can use Sketchup’s Undo (Ctrl+Z) or Edit > Undo options to revert back to previous stages and make necessary adjustments.

Congratulations! You have successfully extruded a curve in Sketchup. Now you can further edit, manipulate, or combine these shapes to create more complex designs and models.

Tips for Better Extrusions

  • Plan Ahead: Before starting an extrusion, visualize your desired end result and plan accordingly. This will help you make better design decisions throughout the process.
  • Experiment with Different Shapes: Don’t limit yourself to simple curves; try out different shapes and combinations to create unique designs.
  • Use Guides: Utilize Sketchup’s guide tools (such as tape measure, protractor, etc.)

    to align and position curves accurately before extruding.

  • Group Objects: If you are working with multiple objects or curves, consider grouping them together before extrusion. This will help maintain organization and prevent accidental modifications to other elements.

With these steps and tips in mind, you can now confidently extrude curves in Sketchup and take your designs to the next level. Happy modeling!
