  • Explore more shortcuts in the help menu within Onshape.

Step 5: Utilize the Help Function

• Onshape provides an extensive help function:
  • Access it via the question mark icon in the toolbar.
  • Search for specific topics or tools to find detailed guides and explanations.

Step 6: Control and Navigate in 3D

• Practice navigating your workspace:
  • Use the mouse scroll wheel to zoom in and out.
  • Click and drag to rotate the view.
  • Use the right mouse button to pan.

Step 7: Create 3D Geometry

• Start by creating a new document.
• Use the Sketch tool to draw shapes:
  • Select the Sketch icon from the toolbar.
  • Choose a plane to sketch on (e.g., top, front, or right).
  • Draw basic shapes such as lines, circles, and rectangles.

Step 8: Understand Sketch Elements

• Familiarize yourself with the various sketch elements:
  • Points, Lines, Arcs, and Circles.
  • Learn how to use these elements effectively in your designs.

Step 9: Apply Constraints

• Constraints help define relationships between sketch elements:
  • Use horizontal and vertical constraints to align elements.
  • Utilize dimension constraints to specify exact measurements.

Step 10: Make Modifications

• Learn how to edit existing sketches:
  • Right-click on sketch elements to access options for modifying.
  • Use the 'Edit' function to make changes as necessary.

Step 11: Create New Sketches on 3D Bodies

• Once you have a 3D body, you can create additional sketches:
  • Select the face of the 3D body where you want to sketch.
  • Use the Sketch tool to add details or features to your design.

Step 12: Export Data for 3D Printing

• Prepare your model for 3D printing:
  • Click on the 'Export' option in the toolbar.
  • Choose the desired file format (e.g., STEP, 3MF, STL).
  • Follow the prompts to save your file.

Step 13: Use a Slicer for 3D Printing

• After exporting your model, use a slicer software to prepare it for printing:
  • Import the file into your slicer.
  • Configure print settings and slice the model.

Step 14: Complete Your First Exercise

• Download the exercise PDF from the provided link.
• Follow the instructions to model an inlay for a soap dish, applying everything you’ve learned.
