Since I have used Visual Cad for 20 years and I am comfortable with it there is really no reason to change to something else. The program is updated on a regular basis so it stays current. I owned and operated a business where I designed and built special material handling equipment so I used the cad program a lot so it still feels comfortable. I can remember most of the commands without looking them up and I can also use the menu/mouse for the less frequent commands. I use it a lot to check parts as I make them. If I want to know how far to move the cutter I can just measure it in the program. Want to know if two parts fit together select one and move it to match the other part.
