There are a lot of good softwares out there, selection really depends on your situation and needs. I would “demo’ as many softwares as possible to see which one fits your office best.
For Autocad, Raincad for Autocad works well. It runs in Autocad as a toolbar, similar to Express Tools. You still have the full function of autocad while adding some very powerful tools for irrigation, symbols libraries, hydraulic calculation, sprinkler placement, pipe placement, databases, etc. Everything is saved as a .dwg so there are no issues opening files.
Can anyone recommend an irrigation efficiency software?
