I have a paper & pencil sketch of my robotic design and I was wondering if there is anyway to easily create a CAD model by scanning my sketch into the computer. I user Google SketchUp and Alibre Xpress (yeah I'm cheap) and I can't afford anything "more advanced". If there's anyway to do this, I would love to know, or if you could point me to a tutorial, that would be greatly appreciated.
The problem in asking about ‘easier and more intuitive’ is that what is easy and intuitive to me isn’t maybe for you. However, being a draftsman by trade, here are MY feelings.
Autocad (which I use day to day) is very expensive and a very steep learning curve. Same with Microstation.
I believe there is a version of Turbocad that is free. This is probably what I would suggest, even though I don’t use it myself. There will still be a steep learning curve initially however. You cannot really compare sketching tools with CAD
I know that many hobbyists however have successfully made the transistion to Turbocad, which is the main reason I recommend it.
