Although it's somewhat absurd, the reason I'm reluctant to try existing free CAD offerings is, at least in part, because they are not explicitly infinite. My sense is that I'm going to run up against limits, almost immediately, and I'm going to spend a lot of time dealing with those limits, which I'm reluctant to do. My sense is I'm likely to not get very far because of those limits. I know people get places with CAD, but my sense is they can only do so if they have unusual faculties, and that the key to building a CAD which is accessible to most people, and not just a few people, is to build one that is unlimited. I say this is in fact not hopelessly utopian.
