Yes, there could be some improvements with the CAD tools but the biggest thing for you to overcome is to stop trying to use Chief like it was Autocad! Vastly different. With Chief you have to do things from a 3D mindset whereas in Autocad its all about lines, circles and arcs. 2D. I use both programs, along with a touch of a couple others, and what I find is that I had to decide which program was going to be my "primary" program and then start thinking in that way versus just what I had always done before. My choice is Chief and now when I use Autocad, which is unfortunately too often, I can't help but realize how antiquated it is!
The use of 2 very different programs such as what you are doing can be a real challenge at times. Mentally. If you want to use Chief primarily then I would suggest stop trying to make Chief work like Autocad. Spend that time instead learning how to better use Chief. Yes, change some of the key commands to what you already know where you can but beyond that let it go. Learn how Chief works and go down that road....., or not. It really is a choice we make. Best of all to you in the process!
