I use 3rd planit, and after testing several programs I found it to be the best. Maybe for someone without CAD experience it is quite difficult, but the learning curve isn’t that steep and the manual is very thorough and easy to understand.
Hi:
Just because you have found a computerized drafting & design program a help doesn’t mean that everyone will either need one or want one.
The learning curves are steeper than stated by the designers, there are bugs in all of them, and they are much more expensive than paper, pencil & the largest eraser you can find. Oh, and don’t forget that you need to have computer to use one, so add that to the cost.
Add to that the fact that designing a layout is not the same as building & operating it.
I use 3rd Planit, but paper & pencil work for the simpler designs.
