OnShape Demo Multiview Sketching

In this tutorial, we walk through the workflow of creating a Multiview Sketch in OnShape. Whether you’re prepping a file for the 3D printer or just finishing a CAD assignment, mastering the Drawing tab is a non-negotiable skill for any engineer. We cover how to set up your views (Front, Top, Right, and Isometric) and apply some of the essential dimensions to ensure your part can actually be manufactured. Think of this as your Quick-Start Guide. We’re covering much of what you’ll need for most class projects. For specialized features or advanced dimensioning and tolerancing, we’ll dive deeper in future lessons and video sessions. --------- Video Summary --------- Creating the Drawing Sheet [00:20] Starting from a finished part, you create a new drawing tab by clicking the plus (+) button at the bottom left. I choose a standard template and selects the active part to begin the layout [00:43]. View Placement and Orientation [00:54] Onshape defaults to the "Front" view, but I change this to the Top view because it contains the most unique features [01:31]. By clicking and dragging, I generate the: Front/Base View (from the selected Top orientation) [01:40] Top View (dragged above the base) [01:48] Right Side View (dragged to the right) [01:55] Isometric View (dragged diagonally) [02:02] Enhancing the Isometric View [02:32] To make the drawing more readable, I right-click the Isometric view and select "Show Shaded View" to provide a realistic visual of the part [02:39]. Dimensioning Best Practices [02:54] Using the "D" shortcut, dimensions are added. Key rules mentioned include: Placing shared dimensions (like height or width) in the middle between two views [03:32]. Keeping dimension numbers on the outside of the drawing geometry to avoid clutter [05:24]. Using the Radius/Diameter tool for curves and circles [03:58]. Positioning Features [04:49] For holes and polygons, I demonstrates dimensioning the center point relative to the edges of the part so that a manufacturer knows exactly where to place the feature [04:56]. Hidden Lines and Specialized Tools [07:29] To show internal features like a hole or a chamfered bottom, I right-click a view and selects "Show Hidden Lines" [07:41]. I also uses the specialized Chamfer Dimension tool to automatically show both the angle and the setback distance [09:19]. Conclusion [10:02] The video wraps up by confirming that these basic steps—placing views, shading the isometric, and applying dimensions—are the foundation for professional engineering drawings.
