Here's a South West Isometric view of my latest CADWorx creation. It's a Fire Tube Boiler, a Horizontal Thermal Oxidizer, with a custom Burner. I created these out of my head, with CADWorx Equipment 2014, CADWorx Plant Pro. 2014, and of course AutoCAD 2014. This is just practice, but it's modeled with Equipment, Piped up with Plant Pro. then assembled in AutoCAD with Xrefs.
