# Using measurement tools

Measurement tools in GEOM are necessary for getting different data concerning created or imported geometrical objects. They are:

- Basic properties

- Center of gravity

- Axis of inertia

- Bounding box

- Min. distance

- Tolerance

- WhatIs

- Check

To use measurement tools:

In the main menu select Measures submenu.
