Hi,
I am trying to extrude a closed curve, using Extrude Planar curve/straight but its only allowing me to move in the +_ Z direction 
What have I done/not done that will allow me to go the direction I want?
Hey Sweeney, posting more info can make easier for people in the forum to help you out.
(add images or the gh file next time)
I think you may be using the wrong component.
In the example below, all vectors work if you replace them in the direction input.
simple extrude.gh (8.9 KB)
If you mean using the ExtrudeCrv command on a planar curve, then by default the extrusion is perpendicular to the plane.
To override this look for the Direction option in the command line while ExtrudeCrv is running.
You can set the direction to whatever you want by selecting a beginning point and an end point (you may need to set these up beforehand if there aren’t any convenient points already in the model).

Cheers, still getting used to the system really loving it but sometimes when your new to a program it is normally just something like this that you forget to check or switch on or off.
looking at it fresh this morning I realise that what I had drawn was not particularly flat to the plain so i think that was also not helping.
Thank you for your help
