I am looking for the same thing! The only thing I found (ConceptDraw) seemed too complicated to be easily utilized, and didn't allow photo uploads, which is the feature I most want right now. What I really want is the Punch one, but for a Mac. Doesn't exist. :(

What if, Worm, no decent professional landscape designer or architect would touch your software package with a 10 foot pole? That would mean ... uh ... that those who have used your software of choice would all be ... uh ... homeowners and DIY garden designers. Except the experienced, creative homeowner garden designers probably wouldn't touch the program either. If you want someone to tell you the program is great, then, okay, I volunteer. It's wonderful. It solved every problem I've ever had. Well, I couldn't really figure out what the heck I was doing, but I'm assured by people in the know that my work with this program is a strong example of what it can do. Now, you have several responses in this thread from real pros and real experienced homeowners, some of whom have also taken design courses. They are in the cutting edge of landscape design. One said put "software" in the search box. You said you put the program name in and got nothing. Doesn't that tell you something ... There is a pretty good chance that there are real drawbacks to these tools ... Not just specifically, but generally. Part of the problem has to do with the way that photos trick the eye and create overly two-dimensional representations. They are too divorced from what happens on the ground. So, I'd still recommend putting "software" in the search box of this forum. Some of the discussions were at some length. Once you know the basic weaknesses of these programs, your own comfort and expertise with software evaluation should help you to know whether Realtime landscaping photo makes sense for your needs.
