Getting Your Design Started

Protocase Designer now includes a Machined Shapes category under templates.

To begin, select the Machined Cube template, you can expect more shapes & templates to come in the future!

You can customize the finish, material, and dimensions of your part, as well as add Chemical Film Conversion Coating for Aluminum, and Passivation for Stainless Steel. Click on the Extras tab and check the box labelled Chemical Conversion Coating or Passivation.

Once you've selected your desired material, finish and dimensions - click the "Start Designing" button to view your part in 3D and begin making some edits!

Creating Your First Sketch

A Sketch is the starting point of most designs. Think of it like drawing a 2D shape on paper. In CAD software, a sketch is created on a flat surface (like the face of a part or a base plane) and consists of lines, circles, arcs, and other geometric shapes. These 2D outlines are the foundation for creating 3D features like holes, pockets, or solid bodies.

Example: You might sketch a circle to define the base of a cylinder, or a rectangle to later cut a pocket into a part.

In the 3D view, you need to first select the face which you want to create a sketch on. You can do so by clicking on New Sketch and selecting the face.

Drawing 2D Shapes

After selecting your face to draw your sketch on, it will open up the 2D sketch editor. For a more detailed look at this window, see Face Editor Overview When working with diecast enclosures, it is possible to incorporate cutouts or through holes/features. By adding a rectangle cutout, it will be treated as a through-feature by default. This means that the cutout will be a pocket extending to the full depth of the material, effectively cutting all the way through.

There are three basic types of cutouts available for these enclosures:

• Circle
• Rectangle
• Line

If you want to adjust the depth of your feature, you can do so by entering your required value into the Depth tool under the Properties window on the right-hand side:

Protocase Designers built in design checks feature will advise you if the pocket you've created cannot be manufactured.
