Description

Context

This macro has been written mainly so user can access a quick & concise information about an object physical properties. This aims particularly at preparing object packaging & shipping.

Usage

Select an object and run the macro. It will display in a message box :

• Object volume in liters
• Object boundbox dimensions in millimeters
• If object has been selected by clicking an edge, its length is displayed in millimeters
• If object has been selected by clicking a face, its area is displayed in meter squares

Installation

At the moment, the macro isn't available from the addon manager => PR submitted : https://github.com/FreeCAD/FreeCAD-macros/pull/52 So you have to copy the below code and paste it in FreeCAD macro editor.

For more detailed explanations, see the How to install macros page.

Script

Limitations

• Only one object at a time
