found a strange bug.

When I have a cropped view with Areas a family I made leaves a white spot. Without the crop it works just fine? 

So the white area under the docks only happens with a cropped view. Strange?

 

kind regards Ron

Did you mean Rooms ?.If so,  probably there is difference with room height and view range height. 

[ron_adst]

Noope - Area's 

1 family - a floor - 4 area boundery lines and the area.

the only difference is the crop in the viewport

maybe its a bug 🙂 what revit do u use? 2018.2 has improved some bugs. if you send file, ican have a look 

[ron_adst]

2017.2 - business policy.....

Could be something in the furniture family?

Have you tried turning furniture off? Does it go away?

[ron_adst]

No furniture in my project. Only a generic family. 

It also happens in Revit 2018

[cbcarch]

I see--well, perhaps it is the overhead garage doors at the loading dock ( on the site plan view they looked like furniture) causing the white spot.

Something with the door family?

[ron_adst]

I made 2 views - crop and no crop

Here you don't see anything strange. But the moment you print it goes wrong.

the problem is where the loadingpit is under the floor. 

[ron_adst]

the loading pit is the problem I'm afraid......

[SteveKStafford]

If you temporarily remove the loading bay families...what happens? Have you examined that family more closely?

[ToanDN]

Does it happen to rectangular crops or crops with edited boundary?

[Sahay_R]

Edit the family? (grasping at straws here....) Possibly replace the family? Try putting in a row of toilets instead (and no, I am not kidding) - see if the same white spot occurs...... if it does, then re-examine the original family.

Edited Crop windows simply DON'T WORK - at least; they appear to work, but will bite you when you have 400 drawings to issue one sunny afternoon.

This has been an intermittent issue with plenty of other strange symptoms including 500MB PDF files, missing text, drawings not printing on sheets, and the little gem you've found - random white blockouts in any kind of shaded view.

Simple fix - don't use Edited Crop windows.

Even simpler fix - Autodesk fixes the bug that has been around since Edited Crop views were brought in. They've been trouble from day one.
