FlightGear Modelling FAQ contains interesting answers to FAQ. It is work in progress...

Which axis in Blender is pointing north?

The X-Axis will point north in FlightGear, after you have placed your model using the UFO. Please note that it can be rotated after hitting = (Tab ↹ in older versions).

What is the unit used for models in FlightGear?

Models are created in metres. So one Blender Unit will be displayed as one metre.

What software could I use for creating 3D models?

You could use any 3D software you want. The only requirement is that it exports to .ac or to a format that could be exported to .ac using other software. Examples of good, often used (free) software are:

• AC3D
• Blender
• SketchUp
• Wings 3D

Blender does not export the texture reference to AC3 files! What can i do?

Propably you have tried to use material textures. These are not exported to AC3 files. Use UV mapped textures instead and they will appear in FlightGear! (see tutorials)
