I have found a calculation error in the floor joist, wall stud, and roof rafter spacing in the House Builder plugin

I build houses with Habitat for Humanity and wanted an easy to use tool to model our house plans in SketchUp. I found House Builder. It is a good basic tool.

As I was entering our current floor plan I noticed that my 4'x 8' sheet goods were not landing at the center of floor joists, wall studs, and roof rafters. I looked closer and discovered that the spacing between the first and second objects was off by 3/4". The tools use the entered On-Center spacing for all objects...not good when building a structure.

I've emailed the maker of House Builder and am waiting to hear from them.

This will be an excellent tool if they address the calculation error.

I'm posting here because I see that there are other House Builder posts on this site.
