My name is Dan, I’m a project specialist at an online pipe and fittings distributor.
I use Sketchup personally, but have used it on a professional basis to design pipe and fittings structures.
I use Sketchup mainly because it’s free. I do a lot of DIY projects at home, and I quite enjoy being able to model them for the boss (AKA my wife). I also really enjoy the user interface. It took some getting used to, never having any experience previously with any CAD or 3D modeling software, but it didn’t take long.
I would say I’m an intermediate user. I’m still not venturing too far out into extensions, and I’m sure I’m not using all the tools to my benefit. However, when I use SketchUp at work, we use PipeAlongPath to make builds easier, as well as a number of dynamic fitting components.
My current setup is SketchUp Make 2017 running on a Dell Precision with an i7 and Win10Pro.
