I have selected File> Print> Print Model and printed out my model. How do I assemble it?


The Model Maker allows you to create a template of your plan that can be printed to scale and assembled into an actual 3D model. Three groups of templates are used in the process. Walls and roofs are printed separately. These can then be placed onto a floor plan view, which is printed as a layout for the entire model.

Since different people build house models in different ways, the Model Maker focuses on providing the most necessary tools. It may not necessarily give you everything you might want in order to build house models your way.

For example, you may want to affix tabs to certain wall or roof edges to help attach them to their neighbors. While you can draw some of these things onto printed sheets, the system does not provide them automatically. What it does provide is accurate templates for wall and roof sections. Combining these with your own skills helps you create professional quality models.

The best way to understand how the various options affect the final product is to make a very simple two story plan and try them out. 

To print the model template

  1. First, launch Home Designer and choose to Open the plan.

  2. Next, select File> Print> Print Model  to display the Print Model dialog.

  3. Within the Print Model dialog:

    • Printer - Use the Name drop down menu to select the printer for your model.

      Typically, larger sheet sizes are better, and Landscape is usually the best mode for printing models. If Landscape is not your default printing mode, it can be selected under the Paper heading.

      Keep in mind that all of the Home Designer programs do have page size limitations when it comes to printing, and you may want to verify that your version of the software can print to the size that you have selected.

    • Scale - Specify the Scale to be printed in inches per feet.

      A simple ratio (1:48 for example) is used for metric plans.

      The system arranges as many wall or roof sections as possible onto a single sheet. If any wall surface, roof surface, or floor plan view covers more than one sheet, it prints by itself on the number of sheets required. Models with large surfaces may require a lot of paper.

    • Print in Color - This option depends on whether you have a color printer. Check this box to print in color.

  4. Once you have set up everything appropriately, click Print to print the model, or click Save as PDF to create a .PDF file.

Assembling the model

Once the templates have been printed, they are ready to be assembled.

You will need scissors and an adhesive and a rigid material that can be easily cut and glued, such as thin cardboard or Styrofoam, to provide support for the 3D model. 

Floor plan view template

  • Begin by laying out the floor plan view, which is used as a layout for the entire 3D model. If your floor plan view template printed on a number of sheets, they should be combined into one. Exterior and interior wall surfaces should match throughout.

  • Adhere your complete floor plan view template to a sturdy and dedicated surface to provide support for your walls.


  • Walls should be cut and fixed to a rigid backing so that they can stand on their own and support the weight of the roof or floors above them. How they are cut and assembled varies depending on the desired final appearance of the model and how they were printed.

  • It may be helpful to take the thickness of the rigid material being used into consideration and override the scale thickness of the walls so that it agrees with your material thickness.

  • If your walls were resized in the Print Model dialog, you may see unwanted lines between floors that should merge together seamlessly. This is usually due to walls whose exterior surfaces match but overall thickness does not. You can prevent this by checking Use Scale Wall Thickness, which prevents walls from resizing. This is best if you do not want to print the interior wall surfaces, or are using a modelling material that closely matches the scale thickness of your walls.


  • Roof planes are joined together when possible before printing. For each roof surface, the fascia and soffit surfaces are attached at the eave, so that the least amount of taping produces the roof and adjoining surfaces.

  • All flattened roof/fascia/soffit surfaces are placed into a CAD detail named "Model Detail." This is overwritten and updated each time the roof group is printed for a particular model. If the roof or portions of the roof need to be reprinted, those pieces can be printed from the detail.
