I'm just starting out in making geotrax layouts. This is where you'll find more soon. For now I've been making a Geotrax Visio Stencil set. Note that connectors have been placed on each track segment. You may need to zoom in a bit and Visio can be pretty picky about them, but it is possible to connect them correctly every time once you learn how. It's impossible to describe how, but make sure you're zoomed in far enough. The latest versions are described below:
Geotrax Visio Stencil v0.3 - Everything from v0.2 plus L2 of Grand Central Station and a bad version of the GCS Ramp (I think my dimensions might be a bit off, but my son wanted to play with it and preempted my drawing). Note: all the pieces can be seen in the image above. All pieces come in a full-size and 1/10 size stencil but only the 1/10 size (and a few full-size) have connection points.
Geotrax Visio Stencil v0.2 - Contains all standard track pieces, the clock tower (purple), Rainbow Bridge, and L1 of Big City Lights. Also contains the Big Ramp from Working Town. I'm using Visio Layers, but don't have much experience with them so they may not work as intended.
