I managed to create a 6 based on your point 1, i will also need more patience in fine tuning the 6 but looks good for now.
I managed to use point 2 as well, is just that i need to find a way to revised the figure, so if the figure shows 177.7deg using angle dimension tool in actual fact the led wall angle bracket should be at 2.3deg ( hence this is to reflect on the sheet so we know what angle should the curve bracket to be set at.)
Thanks alot for your help and the short video guide is very helpful.
