Designing piping is very straight forward, once the classes are set up draw centerline, associate it with a class and diameter and let ISOPipe do the rest.
Using Pipe Class builder allows the modeller to build from centerlines with no input from the operator. once set up the classes drive the modelling and start to create the intelligence in the model from the start
Design Exotic non standard equipment is not a problem and new geometries can be made on demand to keep your model accurate and clean
Create any flange you like for your equipment with the mating face editor.
Create any standard steel extrusion and any shape you wish for custom extrusion and create polyhedrons from point data.
