Drawing and painting brick or roof textures was a skill that i lacked. When you are building structures, you really don't want to spend time and energy getting the lines straight and painting correct.

This is where Evan Design's ModelBuilder comes in to fills a niche. It is an tool to select, assemble textures and print structures easily. The software is very intuitive for beginners as well as experienced computer users, and  there is even a walk-through and an assortment of tutorials to help you along the way to help you build a realistic model.

When you start the application, you are presented with a dialog box asking you which scale you are modeling. Some of the scales presented are Z, N, HO, S, O, OO, Standard Scale, G, One Inch among others.

After you select the scale, you will never have to convert real to model dimensions again. If you have to make a structure that has a real world dimension of 10' x 20', you select your texture and make it 10' x 20'. This is a great time-saver for everyone modeling using Modelbuilder.

The other strength of this application lies in the amount of textures and architectural elements available. There are over 500 images. Material Categories include: Siding, Industrial Siding, Metal, Rusty Metal, Wood, Bricks, Block/Stone, Shingles in Asphalt, Wood and Stone, Cement/Stucco.
Window Objects include: Factory, Residential, Miscellaneous, Arched
Doors Objects include: Residential, Factory, Wood, Arched, Garage. Also Shutters.
Other Categories include: Material Trim, Lattice/Grills, Boundary Walls, Store front, Horizontal Trim, Vertical Trim, Utilities, Trees, Junk, Cornices, Building Extras, and Stairs. 

Here are a few samples:

To get you started Modelbuilder comes with built-in plans. You could build a track side shed, service station, railway station, grain shed, 1/2 Quonset service garage and an alley garage. You select a plan, apply textures and print. Then use the building plan outline as a guide to cut your structure.

You can also import your own building plans in WMF format but with the last update (1.6.2) they have added Paper Tools that gives us templates for Roof lines and glue tabs. You can now use this feature to create any building plan.

ModelBuilder also allows you to import images in JPG or GIF formats. This opens up a lot of creative opportunities. For example, you could take a picture of your house doors and windows and import them in to create your unique model. You could also create signs in any graphic application and bring them in. The possibilities are endless.

They have also included a Brick and Siding editor which you can use to create unique brick and siding patterns.

Here are some features that Modelbuilder has going for itself:

Easy of measurement: You select your scale, type in the real-world dimensions of the walls and you are done.

Vast selection of textures: The variety and amount of textures will let you fill your layout without any two buildings looking the same if you so want.

Importing elements:  Even though it has a lot of doors and windows, the import feature allows you to grab any image of a door, window or any other architectural detail from the internet or your own photos to give you that unique building.

Something that can be improved in Modelbuilder.
There are some memory issues with Modelbuilder. If you open and close a lot of plans in one session (without closing Modelbuilder) Windows throws up a low memory warning. Hopefully, they are working to fix this in the next version.
