I would like to follow up this question and hope there is improvement on Revit after 5 years. In Hong Kong, there used to be a government standard for rise/drop symbol. It can be an obstacle to implement Revit if the symbol cannot be exactly the same so that Revit produced drawings get rejected. (though the Revit symbol is close to, see attachment)
Having read through this rather old thread, I'm also looking to customize the rise/drop symbols.
I work for an architectural practice and the pipe tool is particularly powerfull to design/coordinate the drainage systems for architectural purposes. As such, we need a symbol representing SVP's, WVP's, RWP's, VP's, etc.
Previously we used simple vertical families, but the pipe system allows much more advanced design allowing various routing directions in one continuous run. We're now working in Revit 2015 and this still doesn't seem to allow editing of the pipe symbols...
Any update as to when this may become a feature?
