I am having trouble with plumbing section cuts showing up in my hvac views. Usually if when this is the case with another discipline (electrical for example), we just change the disipline in properties to electrical and it does not show in my view/sheets. Because plumbing & hvac is a sub discipline of Mechanical, it seems that all plumbing section cuts show up in my sheet even if I change the sub discipline to plumbing. There appears to be no way of putting section cut lines on worksets so how do I fix this?
