3rd PlanIt is the most automated, comprehensive and easy-to-use

track planning tool ever made. Better tools let you create better designs!

Designing a Railroad?

Thousands of layouts have been designed and built using 3rd PlanIt. From tabletop Z scale, through 4x8’s, room-sized layouts, basement and outbuilding empires and a full-scale ethanol plant, 3rd PlanIt is the CAD software chosen by the most discriminating hobbyists.


3rd PlanIt now includes an incredibly powerful design tool: SoftTrak. Draw track from point to point, while SoftTrak creates the curves and easements automatically. It’s like using a multi-segment spline, but made of the same track elements used in prototype railroads. The curve radii and easement lengths are optimized to fit in the available space. You are able to design your layout to professional standards without all the learning!


Take a look at 3rd PlanIt’s full features set in the rest of this site, and you’ll find everything you need to create a layout you never considered possible.

You’ll always find useful new features in each new version. v10 offers powerful splines and the ability to have holes in meshes.

v10 features splines, holes in meshes

This paper shows you a new way to design sidings with SoftTrak. See the new ways you can design and modify your track plan!

New ways to design with SoftTrak
