I understand this is a very basic question. Just started to learn this software and need to get familiar in a short time. Any suggestions would be highly appreciated.

alan-tucson,

The input screen has "Edit + Distance" function to obtain the length between two nodes that you would input the node numbers. Or it could obtain the length from the origin to the current node. Pull-down function also has hot-key "Alt+D".

... or perhaps use the BOM section of the "Miscellaneous Report" if you're after total pipe lengths for the model.

thanks to R Yee and Richard Ay for the response.

Follow up:

the "Edit + Distance" function gives out only the straigth distance between two nodes instead of the real length of the pipeline.

I did not try "Misc Report" yet. I need to make sure the pipeline is modeled correctly, including the length.
