Carbon Steel Buttweld Fittings 3D App is used to create 3D Buttweld piping drawings. The unique features in this app will make 3D piping drawings easier to produce from an isometric view point.

The unique Pipe Spool Feature allows you to draw a pipe spool with two selection points with selected start and end fittings.

This feature alone will save many hours of pipe drawing time. First draw the centerlines for the piping route, and then you will be ready to drop the fittings at each point for elbows and tees. Or use the Pipe spool feature to go from point to point, two points at a time with the fittings included.
