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.

Challenging But Works

Colleague gave me some pointers and I got basic elements of the program to work! Hooray. Thre is a sharp learning curve, and undoubtedly the program has many "features" that I'll never use because I will never figure out how to use them. But for basic track layout planning it can be a useful tool.
I would not rely on the product for final installation of the planned layout (you will definitely need to fit and adjust) as there are too many uncertainties in the track layout plan produced by the program -- it suggests a degree of precision that I don't beleive is warranted -- but using this program did show me that PECO #6 turnouts would not work and that I needed to use #5 turnouts. (I will still test fit both.) That alone was informative.
A user guide would be helpful.

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!
