# Plate

## Introduction

Flat plates are common structural components on many robots.

## Modeling

The basic process for modeling a plate is demonstrated in the following animation.

Some considerations are as follows:

- Some CAD programs require trimming the circles into arcs before extruding.
- A curved exterior can be achieved by connecting circles using arcs instead of lines.
- If you prefer using the hole tool to extrude holes, skip drawing the inner circles or mark them as construction.
- In the event a hole is too close to the boundary of the circle, you may need to redraw the boundary.

### Constraints

Lines should be constrained to each circle using coincident {{coincident}} and tangent {{tangent}}.

Circles which are the same radius should be constrained together using equal {{equal}}.
