I got some time to check a demo version of CSI-Concepts Unlimited v4 to compare it with the previous release. Though not much time I've spent on it but generally I am impressed with the simplicity and ease of use as I could manage to find what I needed for most basic tasks without referring to its help file and it took much less resources of the computer compare to most other programs. I need to push it to its limits to get an idea of whether it could be a reliable tool for a designer or not. Anyhow it might be interesting for some to check it and post some opinion on it. I put it in a range of products including Rhino, Cobalt and Deskartes products for now. Maybe top of them later after the long-awaited Rhino 4 and Cobalt 8 are out.
I didn't ask any questions in my post here. And what I have written should be clear.
I just introduced a software I'd tried as it might be interesting for some to learn about software developed for designers in particular, and it would be great that others share their experiences here.
