Using Images as References in Onshape Sketches

One of the most powerful ways to use imported images in Onshape is as a reference for sketches. This method allows you to trace over the image or align your design directly to it. Here’s how you can effectively use images as references:

Step 1: Create a New Sketch – First, create a new sketch on the plane where your image is located. This will allow you to draw directly over the image.
Step 2: Insert the Image into the Sketch – Inside your sketch, go to the “Insert Image” option again to bring the image into your sketching environment. You can adjust the image’s position and size if necessary.
Step 3: Trace the Image – Use Onshape’s sketch tools, like lines, arcs, and circles, to trace the important features of the image. This is ideal for designs that require high precision, such as mechanical parts or architectural features.
Step 4: Lock the Image in Place – To prevent accidental movements, you can lock the image in place using the “Fix” constraint. This ensures the image remains static while you work on the sketch.
Step 5: Adjust Your Sketch – After tracing the essential parts, you can delete the image, leaving only your sketch. Onshape’s parametric tools let you refine and adjust the sketch elements to suit your design.

Using images as references in sketches can significantly improve your workflow, especially when working on complex models. It adds a layer of accuracy and ensures your designs closely match the intended shapes.
