I am looking at buying a system design software but as usual, there are many conflicting sources of information and I was wondering whether anyone had an informed view from experience. The more obvious choice is the JVSG software which appears to be well developed now offering a range of options. However, I know that some use Sketchpro for their designs and others strongly support Blue Beam but they both seem more aligned to construction although VideoCAD seems to have a SketchUp plugin free. Any ideas very welcome
