exporting or printing parking level only VERY SLOW

[cr_gixxer]

We are having an issue when we are exporting to autocad or printing to pdf that affectes only the parking garage level. By parking garage level, the times we've experienced this is when the level is below the main floor. We had situations where we have 2 or more levels below the main floor, and the only one that causes issues is the level directly beneath the main floor.
It is significantly slower. From the typical seconds to a minute per floor to hours for the affected level.

Any thoughts to explain this erratic behaviour?

Reviewing things I don't see anything out of the ordinary or specific to those levels that we don't see on other levels.

I haven't noticed in in smaller projects in the office, only the larger ones.

Are you using the standard rectangular crop window or a polygonal? That could be reason number one.
Are you exporting views or sheets?
Overall plans or partial plans?
Is it an issue where the view range is set say 200' below the level? Just because it's not visible doesn't mean revit isn't looking at it and doesn't see it. It's just behind everything else so it won't export, but it may still be being calculated.
Just some thoughts.

Thanks David,

We're using the standard rectangular crop.
Exporting + printing sheets
Overall plans.

These factors are common to the rest of the set, so I don't understand the irregularity.

I'll look at the view range, to see if that is the culprit, but in a project file with 3 levels of parking below the main floor, we have seen the glitch on only the level immediately below the main. All three would share the same view template.

Tried using the "raster" printing?

haven't tied that....fearful it would hurt print quality

[david_peterson]

It will, but it'll print everything. Not always the case with Vector.

I'd suggest maybe trying to duplicate that view with out detailing. Create a view template from the plan the next floor up. Apply it to the duplicated view and see if you're still having the same problem. Sometimes that's easier than figuring out which on of the 1500 settings in VG might be different.

Just a thought.

I think there's still an issue of super-long print/save times and huge PDF files for any sheet that uses a non-orthogonal crop region, i.e. any diagonal lines in the crop region. Seems fine if the crop region is non-rectangular, as long as the boundary lines are orthogonal. But you said you're using the normal rectangular crop regions so I don't know.

If you have a Survey or other Revit/AutoCAD files linked into your project, try unloading them or placing them on a workset that is turned off in that view. It is hard to say what may be causing this problem without seeing the file. Hatch pattern files have also caused problems in the past with printing/exporting. Proxygraphics and nested blocks/exploded xref blocks have also caused issues in the past if they are buried in an AutoCAD file.
