Watch the heads-up display and move the cursor down to (750, -750) and click to lock in the first arc. Use these keys to set the radius to 750 mils (for a 1.5-inch diameter donut). Use the or to change the radius in steps of 10. The and keys decrease and increase the arc radius while the shape is being drawn (so chosen because the symbols are on the same keys). The (without the Shift) will toggle and change the direction of the arc. Use to toggle the drawing mode until the heads-up display shows the “Line 90/90 Vertical (Horizontal) with Arc (Radius: xx)” mode.
Using the (0, 0) point as a reference, click there to start to customize the shape. Click OK to close the dialog and enter the drawing mode. The Overall Height is going to be the same as the width of the donut, 475 mils. The Layer should be any visible mechanical layer. The Body Side should default to Top side. In the 3D Body dialog, set the 3D Model Type to Extruded. Start the 3D body drawing mode from the Place/3D Body menu. PcbLib file, set the snap grid (G hotkey) to create something large and easy to work with, in this case, 50 mils. The dimensions for the donut are 1.5-inch outer diameter, 0.8-inch inner diameter, and 0.475-inch size width. Create the Donut for Use in Your PCB Design The 3D Donut Shape Models These Coilcraft Toroid Inductors. Let’s take a look at creating shapes in your PCB. A 3D donut, however, is what we will be focusing on today. Although a hole cannot be cut out of any of the Altium-created shapes, a donut shape can still be achieved by essentially creating a closed “C” board shape. A board outline can be extremely helpful and can even produce shapes like the polygon (polygon pour). It is generally very simple to create realistic 3D mechanical shapes in Altium Designer ® using the included Extruded, Cylinder, and Sphere shape types in the PCB Library editor.
