I am looking at getting into CAD for our landscape designs. Up until this point I have always done the designs by hand, and it has served us well. However, I feel that moving toward a CAD system might be a step toward greater efficiency and professionalism. So herein lies my question, what specific programs are you using? What is the learning curve like? And is this something that I should go take a college course on? I have seen some wizbang offerings that you import a picture into and go from there, but there is something that seems a little homeowner level about it. But it could just be the product I was looking at. Thoughts?
