I am still cofused about how to lay out my layout.
If I draw a radius on center of track how can I lay track or inclines if I can not see the line I drew?
I am using woodland scenics inclines which are two and a half inces wide.
If I can not see the line I drew at a 11 inch radius how can I curve the inclines?
I know this is a stupid question but I am stumped.
Any helf from all you master builders?

Another way you could do this is you can use a a set of scibes or a compass like the ones we all used in school. set the distance from the point and the pencil tip at 1 1/4" and follow your your first center mark. This will give you the outside of your riser/incline. Then after you have your incline/riser secured you can take the compass and remark the center line on the riser/incline.

Joseph:
If you can draw an 11" radius, you should be able to draw a 9 3/4 and a 12 1/4 radius. I usually draw all 3 when I lay track.
I made a radius bar using an old yard stick. I put three holes in at one end spaced for my centre and two outside measurements, then put holes at the required distance from the centre hole. These holes are big enough for a pencil. I slip the centre hole over a nail and draw the curve, then repeat for the other 2 holes. (Sometimes the hard bit is finding a place the pout the nail!) Just remember to mark the holes as the markings on the yardstick will be out.
(Course, I'm working in a larger scale than N - you might find an 18" ruler works.)
