I'm looking at buying CA possibly, I need to someday draw plans and build on to my house, so looking for something to do that as well, but for now, I'd like to get something that can do simpler things too, like my shop, pole barns, etc. Shop's are probably a no brainer, but the pole barns may be different. I saw one place somewhere say that it's doable with CA, just have to stand on your head. I guess the biggest question, does it have the capabilities of computing the engineering aspects? And that goes for regular designs too, can it give me beam sizes, joist sizes, etc.
