Hello Friends. This is only my 2nd post in this entire forum, but I have been an SU user since V. 2.0. I think it is amazing. I started out as a Traditional hand renderer. I still do that. I generated Persp. by hand for years. I did Autocad, form Z, etc. etc. All too slow, learning curve too steep. I needed a program that I could learn quickly--generate 3Ds quickly, giving my clients multiple views, print out and render over the top. Saves me time. I make more money. I have introduced Sketchup to the College I teach at. It is now in the curriculum. I introduced it into the large organization that I work for (I am an architect for the LDS Church)--it is now S.O.P for a lot of my colleagues! Yeah, we have Max, Z and all the others, but SU is faster and eases the workflow for a lot of us who just hate muddling thru acad. I still use SU in all my work. I am learning Max, only to add another arrow to my quiver so to speak, but I always think about how I can just drop my SU models into max and render from there. I use Podium too. Awesome. Simple does not mean simplistic. Su is a very sophisticated tool--is there stuff that I wish it could do better? yeah. but that is probably cuz I don't pay enuff attention to the forums to find out how other folks have solved my issues. SU is terrific.
