A pipe fabricator can read the drawing and understand pipe routine easily. An isometric drawing is generally on a A3 size paper. To aid pipe fabricator on site, isometric drawings are prepared. But 3D scale model can not be put on a paper, and 3D scale model does not indicate dimensions. A pipe fabricator can understand GA drawing better only with the help of 3D scale model. A0 or A1 size drawing is to big to handle. A GA drawing is generally on A0 or A1 size paper and contains a lot of lines, and may not be easy to understand pipe routine. 2D General Arrangement (GA) drawings are used for fabrication on site.


This is then converted into a 3D scale model, to check interference of pipe lines. In this all pipelines are drawn at zero z co-ordinate. The picture below shows a screenshot of its drawing.Why Isometric Drawings are required?: Generally in the development of a project, a conceptual 2D drawing is first created. Piping Design Software Drawing Interface. Now I want to introduce this excellent piping designing tool, not only because it can give you access to a wide range of symbols, but also because it's a trustable and really user-friendly piping design program. Piping Design Software Drawing Interface The picture below shows a screenshot of its drawing interface. SmartDraw will help you build piping diagrams, HVAC drawings, welding diagrams, and many other types of mechanical drawings quickly. The secret is in SmartDraw's powerful drawing tools and rich content of templates and symbols. SmartDraw's mechanical drawing software is fast and easy to use. It supports the fast and simple design of complex 3D piping systems in plants, factories or large modules. MPDS4 is the perfect software for all areas of piping design.
