We've upgraded to 9.0 from 6.0 and I have to say it's a lot more powerful now for creating irrigation and landscape designs. The past two weeks I've been getting used to it and going through the tutorials comparing how things are now done versus the older program. There has been a learning curve but fortunately a lot of things are the same. The main problem with the program is its Material Takeoff command. It generates 99% correctly but the one area it's lacking in is in the area of fittings especially tees, crosses and reducer bushings when the pipe changes sizes. Guess I'd rather do a manual fittings pickoff which is only about 3% of the whole design process. I still can manually do a fittings pickoff quite rapidly. I especially love the Tied Assemblies area where I can tie sprinkler bodies to our type of swing joints, valves to our SCH 80 TOE nipples and MP-Rotators to the Toro 570Z PRX-4P bodies we use with them. It ties them together and them breaks them out in the Material Takeoff showing all the parts and corresponding prices. I've attached a PDF of one of my practice designs. Although it states a 1/10 scale it was meant to be printed out on our large format 18" x 24" or 24" x 36" printer at work. I've kept it on an 8-1/2" x 11" sheet just for practice at home.
