I'm using acadMEP 2015 and I'm having an issue with MEP objects being hidden or not displaying in certain views. Sometimes when I zoom in the pipes disappear from view, zoom out they reappear, sometimes a length of pipe wont be visible from the top view but it'll be visible in the isometric view. Everything is set to wire frame, I've got a mixture of solid objects and acad mvParts and pipe.
Is this a system performance issue or a setting I need to change?
I've been primarily using Revit for the last couple of years, I've only been using autoCAD recently. Is there a view depth now? I had drawn in some acad walls and lowered them below 0 in the z axis and it was hiding them in the top view... If I made them tall enough to go through 0 elevation they would become visible. I couldn't find a setting and any sort of search for view depth goes to Revit.
