Is your question really:

- which one is the "most used?"

or

- which one is the "easiest to use?"

or

- which one has the most "Bang" for the "Buck?"

thank you PennPiper as u asked the questions i need their answers. Are PDS and PDMS softwares or they indicate some other softwares

piping_engineer, please tell us a little about your background. Your "piping" related education and your "piping" related experience.

If we know this then maybe we can help you better.

i mostly deal with piping and welding related issues. my responsibilities are piping design, generation of piping drawings (both 2d n isometric) rectification of online pipe leakages and piping flexibility analysis using Caeser and also working on AutoPipe now-a-days. for piping layout i use Pro/Piping, a module of ProEngineer.
