3D Software for Designing

I was designing products on paper in 2D with the help of a big eraser.  After awhile I started to think that there has to be a more accurate and easier way to do this.  The answer....SketchUP, 3D software.  It is great for designing products, especially since I have a visual mindset.  It took me some time to figure how to use the program.  What really helped was a website that I mentioned on the previous post.  Now, I'm spending time designing products that I want to offer to consumers. Another nice feature of the software is the cut list plugins, which gives me a list of all the parts with measurements.  It takes all the guess work out of knowing what wood supplies I need when I go to the lumber yard.  If you are thinking about designing, try it out.
