Learn Onshape - Project 4 - Snap Gauge

Introduction

This tutorial will guide you through the process of creating a snap gauge in Onshape, a powerful 3D CAD software. Designed for beginners and intermediate users, this step-by-step guide will help you learn essential sketching and part modeling techniques. By the end of this tutorial, you will have a solid understanding of how to use Onshape for designing 3D parts.

Step 1: Set Up Your Onshape Account

• Go to the Onshape website at Onshape.
• Sign up for a free account if you don't already have one.
• Once registered, log in to access the Onshape interface.

Step 2: Create a New Document

• Click on the "Create" button on the top left of your dashboard.
• Select "Document" from the dropdown menu.
• Name your document (e.g., "Snap Gauge Project") and hit "OK."

Step 3: Start a New Sketch

• Click on the “+” icon next to your document name to add a new tab.
• Select “Sketch” and choose a plane (e.g., the front plane) to start your drawing.
• Use the “Line” tool to outline the basic shape of the snap gauge.

Step 4: Define Dimensions

• Select the “Dimension” tool from the toolbar.
• Click on the lines you want to dimension and enter the specific measurements required for your snap gauge.
• Ensure all parts are fully constrained to avoid any errors during the modeling process.

Step 5: Create Features

• After completing the sketch, exit the sketch mode.
• Select the “Extrude” tool from the toolbar.
• Choose the sketch you created and specify the thickness of your snap gauge.
• Click “OK” to create the solid part.

Step 6: Add Additional Features

• If your design requires any additional features (e.g., holes, fillets, or cuts):
  • Start a new sketch on the surface of your part where you want to add features.
  • Use appropriate tools such as “Circle” for holes or “Fillet” for rounding edges.
  • Dimension and constrain these new sketches as needed.

Step 7: Finalize Your Design

• Review your design for any necessary adjustments.
• Use the “Inspect” tool to check dimensions and ensure accuracy.
• Save your progress regularly to avoid losing any work.

Step 8: Export Your Model

• Once satisfied with your design, go to the top-right corner and click on the “Export” option.
• Choose the desired file format (e.g., STEP, STL) for your snap gauge.
• Follow the prompts to download your file for 3D printing or further use.
