I work with a lot of piping that requires flex connectors. I am not a 100% sure how to create something that would look like that in the plant 3d model, I also do not know how I would create an Iso Symbol for it.
The only thing I can think of is getting two flanges and then creating some sort of wavy surface with AutoCAD equivalent of a revolve tool, but that would still leave out how to get it to show on an iso drawing.
I've got a custom part catalog that I've made up for our stuff.
Roughly the steps are like this:
Note: Iso symbol type & Iso symbol SKEY entries.
I'm having similar issues.
if you use the iso symbol as noted (EXFL Misc-Component) then your iso will work fine as long as there is not any angular misalignment being taken up by the 'Flex Coupling' (plant talks about 'expansion belows' instead of 'flex connectors' - for taking up expansion axialy along the length of the pipe, not for axial misalignment).
If you make a custompart of a flex coupling to connect a misaligned piperun then when the iso is produced (production doesnt seem to work - quick iso does) the flex coupling will show as straight (with dims) and the actual point where the line changes direction moves to the next node on the pipe!
Just wondering if the 'block offset' isogen symbol would work for that. It might look a little odd though.

Otherwise, what I've done for a really odd component is change it to a peice of equipment and just connect to it. Then tag it as an SP item & detail it on another drawing.
Hope this gives you options?
i dont think the block offset will work...the lines arent 'offset', they are 'misaligned'
Ive used the hose symbol (FXFL) its not ideal buut it works the best for the options ive tried.
