Software upgrade

Purchased a software upgrade. Process worked flawlessly. Thank you!

Brian Thomas
Easy to use, a great addition to my toolbox

Very easy to use and understand. I can go from an idea to a completed structure in very little time. Nice way of adding texture and detail to otherwise plain or outdated kits as well. Highly recommend this software!

Evans excels

I really enjoy using Model Builder. It is versatile and provides accurate detailed printouts. A must have.

Stan King
Scaling up to 1/24 difficult

The designs included don’t easily up-scale to 1/24 but I have been able to manipulate them satisfactorily. Not the most intuitive software but the HELP and instructions pretty well show what can be done. I’ve begun a second structure and think it will be another ok addition to the G Scale layout.

Hi Stan thank you for taking the time to leave us a review! Yes, for 1:24 scale, it is hard to fit much on an 8.5 x 11 inch page you can fit into your printer. You could select a larger page size and bring the completed file as a PDF to an office store to print larger sizes. Did you know we have video tutorials here? You have may find them helpful. You can find them at this link: https://evandesignsmodelbuilder.com/tutorials

Saw this in narrow gauge and short lines. I like card board modelling so bought a copy. Download / payment all straight forward. I've only had a brief look at it so far though. Seems relatively straight forward to use and there are building tutorials included which is good. The interface is a little clunky in places but for a home grown piece of software its pretty good.

If you enjoy building in card (I think there is an awful lot you can do with this) I would recommend.

Overall a great software

No matter the scale, this software will help you create structures at a fraction of the price verses other options.

There is a learning curve to the software and you have to think 3D, but once you have that process in mind, you're set.

The folks over at Evan Designs are awesome, who provide great customer service!

Great Products...

The designs really help make a project come to life! Will order more in the future for my N-Scale model RR. Thnxs.

Great Products and Service!

Model Builder is a great product for making model railroad and other mock-ups or finished buildings! It's easy to use and the support provided by Evans Designs is great! Every model railroader should have this in their e-toolbox.
Every time I use it, I find new ways to create more realistic structures.

L. Brumback
Need a flip

Generally great product, but would be improved by the ability to flip drawing objects such as doors and windows both horizontally (for variety) and vertically (for the ability to lay out a small building all on one page)

Thank you for taking the time to leave us a review! Your suggestion is appreciated and duly noted!

Daniel Brewer
Great Products and Service!

I've purchased from Evans Designs for years! David and Shelly have always produced great products, supported them very well, and have gone the extra mile each time I've sought their help! I'm proud to endorse their business and suggest that others do the same!
