Fab MEP Parts Visibility Issues

[koolair]

Good evening everyone,

I'm running sloped piping in fab parts in Revit 2017 and can't figure out why it doesn't look the way I'd expect it to look.

My plan is set to "hidden line" visual style so that lower objects show up with broken lines as they pass under higher objects - this is what I expect from Revit. However, I'm finding this doesn't happen with Fab Parts. For instance, there are floor drains below the pipe, but the pipe looks like it runs below the floor drain (ie, the pipe's lines break to reveal the entire floor drain).

Also, I want my insulation to be 100% transparent, but under MEP Fabrication Pipework category, the insulation subcategory doesn't have a separate transparency setting. So I created a filter for it and set it to 100% transparent.

When I do that, pipes that cross at different elevations don't display properly. For example, my pipe is running in the 4,500-5,200mm elevation zone. I model another line below it running perpendicular in the 3,200-3,600mm elevation zone and when they cross, the higher pipe looks like it runs below the lower pipe.

When I zoom in and out, the pipes look good. But when I stop zooming, it looks all wrong.

When I use native Revit, this never happens, so I'm a little stumped. Particularly because I have to get some new guys on gravity tomorrow.

Anyone else deal with these issues?

Thanks

Sorry for the late reply here, but what version of fab parts are you running?

Does it look right when you print to PDF? Many times objects do not look right in Revit but once a PDF is made it does look correct.

Not sure what you mean. It's the fab parts in Revit 2017. We loaded our custom library from FabCAD using the guid and other wonky cad admin stuff. Basically it's the CAD library brought into Revit 2017 fab parts.

Never bothered to print to pdf. Will check it out.

Actually we're in discussions with Sysque. Really only need it for sheet metal because even for sloped piping, Sysque can't really deal with the real issues we face (afaik). My experience with it was good but it couldn't handle the fitting to fitting combos I need for cast iron pipe but for sheet metal it's the best. For large piping I use Victaulic which is an absolute gift. EXCELLENT add in for cheap. No one cares about spaghetti so we plan on using basic nibco and A53 fittings.

I really really like fab parts for drainage. It's so good not only for initial layouts, but also revising and editing that I'm tempted to overlook its navis export flaws and tagging/BIM issues. I can crank out a layout ready to build in 3 days, what would take me 3 weeks in Revit with Sysque components. It's also easy for beginners so they can spend more time learning plumbing code.
