How would I remove the following from showing up.
-The NPS of a pipe, fitting or valve.
-Any dimensions that do not have a length of pipe. (ie I do not need to know the height of an olet on top of a pipe, or the measurement of a flange and elbow.
-Any component that is part of another line number
For the 'other component' part of your question, if you do a Production Iso and pick a line number, it shouldn't be putting parts of another line number on it. If it is, I would check the part in the model and see what line number is assigned to it.
They are assigned to different line numbers. The other line shows up as dashed lines, indicating it is a separate line, but I do not see the point in it being on the drawing and would like it to be removed.
