Thanks again for your reply, however it does not seem to be working for me. Maybe i missed some setting somewhere, I created a file called Guide Line test in AC 14, it all works fine in 14.
In AC 15 when i open the same file with the same WE i try it both ways with relative coordinates off or on it makes no difference. The only time the incremental guidelines seem to work properly is when i start drawing from the project origin or the user origin.
The attached image shows in the first row my test file opened in AC14 with relative coordinates on and off, all works fine. The second row shows the same file opened in AC15 with relative coordinates on and off, you will notice that the incremental guidelines both reference from the project origin, with relative coordinates on the guidelines should be starting from where i start drawing (the edit origin). The only time it seems to work properly is when i start to draw from the project origin or the user origin as can be seen in the last image on the second row.
