I can't find the Retopo menu I am very new to blender but have made some good progress recently. I have a curved surface that I need to cut a precise hole in and from YouTube videos it seems that the Retopo method is the way to go. The problem I have is that I can't get to the menu where I can call upon it.

I am using a MS Surface Pro 3 with a Bluetooth keyboard. It doesn't have a dedicated F9 key but if I push the F key and the F9 multi key it should be the same thing.

Can anyone help?

Cheers
Chris
The video you mention is very old, it uses blender 2.49 which was before the major interface overhaul that started with blender 2.50. The mesh panel you are looking for had several things grouped together that are now in different places.

The retopology part that you are after is now better defined under snapping options. With transform snapping enabled set the snap element to face and you can have vertices you move snap to an existing surface.

Blendercookie has a more recent retopology video that you should find helpful.
