# 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.

## Appendix

### Constraints

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

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