Fine functions for freeware

I’ve spent a couple of days getting to know this software as I plot a new layout, my first in many years. It’s remarkably glitch-free and highly functional — all possible stars for that. The tutorials and documentation are very limited, as far as I can tell, so getting acquainted with the program’s basic functions is trial-and-error. That’s the only problem I’ve encountered, and it IS possible to figure things out as you go. Compared to other CAD I’ve used (non-model railroad), it’s not a steep learning curve. And it’s a very good teaser for the Pro version.

Exactly what I wanted!

I’m just getting into Z-scale modeling, and was in the midst of planning my first permanent layout. To help me with that task, I was actually just looking for a good 2D scale-drawing/CAD program, from which I had planned to make my own track-section templates. I was surprised to find this amazing tool, pre-loaded with ALL the Marklin and Rokuhan track sections available. For my needs, it is just about as perfect as I could imagine. Very easy to use, if you are even remotely familiar with other types of diagramming software. It’s even fun to use. I currently have the free version, but will happily pay for the upgrade to the $40 version, just to support the developer.

Great for Slot Car Layouts!

This is a great app for designing slot car layouts! I’ve used it for both 1/64th (AFX/Tyco “HO”) and 1/32 Scalextric track. Just fantastic! I had been doing layouts in Adobe Illustrator, creating my own library of track components. But this app is SO much better. Providing parts lists, track lengths, overall layout dimensions, etc. Easy and intuitive interface.

Only 3 minor suggestions for improving the Slot Car side of things:
1) Make sure to add in all the Scalextric track options (starter sets include 2 long straights - power and mechanical lap counters - not included in the library).
2) Calculate lane lengths separately (Left and Right lanes)
3) Allow and calculate for 4 & 6 lane layouts.

Thanks for a truly great app. I’m planning on upgrading to the Pro version soon!
