A thin and flat piece of plastic containing various cut-out shapes. It is designed to increase the speed and accuracy of the drafter

The description you provided refers to a drafting tool known as a "template" or "stencil". This tool is used in technical drawing and drafting to accurately draw specific shapes or symbols. The cut-out shapes can vary widely, from geometric shapes, architectural symbols, electronic symbols, etc.

Here are the steps to use it:

1. Choose the appropriate template for your drawing. The template should contain the shapes or symbols you need for your work.

2. Place the template on your drawing surface. Make sure it's aligned correctly with your drawing.

3. Use a pencil or technical pen to trace the cut-out shapes onto your drawing. Be sure to hold the template firmly in place while you're tracing to ensure accuracy.

4. Once you've traced all the necessary shapes or symbols, remove the template.

5. Use an eraser to clean up any stray marks or smudges.

6. Repeat the process as necessary with different templates to complete your drawing.
