Sorry but I am having trouble recording a video.
My first attempt did not record the steps in 3D at all - just the start and then the finished product.
My latest attempt is a bit jumpy and does not clearly show the steps - but if you really want I can e-mail it to you (I have your address already but wont send it till you say so).
I won't post it here because it is really not good enough.
I did realise that when placing the roof you click the first 3 points to define the roof slope then I said click the same 3 points to place the roof - you actually have to click the 1st point again (for a 3rd time) to close the polygon.
So it is point 1, 2, 3 then 1, 2, 3, and 1 again.
I have amended the original post.
Barry.
