HOPPY posted:... This now is the "It's Okay if you Laugh" part: I use jar lids and caps of an exact scale size to get the curves and it serves me well. An example is an old mayonnaise jar lid that yields a 3-inch diameter (72-in. scale) circle. Of course, my plans are drawn to represent what would be the center line of the track or switch. I know it's primitive but I enjoy drawing plans this way.

Oh yeah, sounds familiar. I had various jar lids to draw out different track radii. Years ago !
Now, I couldn't be happier with SCARM. I've used it to draw up some of the old sectional track plans from hobby books and magazines and it's often comical to find out how much they fudged the fits. Multi-level track plans might have impractical scenery in an artist's sketch and SCARM 3-D views would reveal the shortcomings.
