I’m no architect and not an engineer that makes and plans the design of conceptual building projects. But I do some 3D designs also as a graphic designer. I’m using different software that is easy to use than 3D CAD programs like Auto CAD. I used to use Google SketchUp and Archicad. They’re so easy to use; it’s your playing Sims 2.
Just recently, I found a free 3D design application for interiors. It’ll help you place your furniture on a 2D plan with a 3D preview easily quickly. It allows you to draw your walls to make rooms or the entire floor plan. Then drag and drop furniture’s/object from furniture catalog that where organized by categories that you may add to you home design. You can also import your designs as blue print, 3D models. You can also add plug-ins to extend your presentations and designs. Create Photo plug-in is what I use most, coz it makes me create and save a more realistic pictures in 3D view.
This app is a must have, create with it, design with it, play with it, make profit with it.
