When it comes to troubleshooting families, this is very rarely a problem, unless you don't want to hand it over to a public forum. In that case, think about getting a private consultant to look at it. Or just lighten up a bit... But that's a completely different story all together.
In the case of a project acting up, it might be somewhat more complicated. Off course you could do a save as, delete all unwanted geometry, views, sheets and then purge the entire thing. But unfortunately, that usually doesn't give you a small enough file either. Revit has the habit of retaining a lot of data in the projects database so it stays bloated.
Another option, which does kill all redundant data from the database (and is way faster too), is this:
- Windowselect the offending geometry and it's immediate surroundings.
- Go to the filter dialogue box and check off all categories you don't want to include
- Group the items that remain (including the item giving you a headache)
- Find the group in your project browser, right click and choose Save Group. This will save just the Group as a separate Revit project. If all is ok this file should be a whole lot lighter then the original.
- Open the Group in Revit to see if the problem is still there. If so, you can now upload it.
If not: then there are a few reasons which could have caused the problem in the first place:
1. for geometry not displaying correctly: it's a Graphics Override. You released this override when Grouping and using Save As. So check your View Template, Visibility Graphic Overrides, Phase settings and so on.
2. For geometry doing all sorts of wacky stuff but doing this in plain sight, the problem 9 out of 10 times lies in constraints you put on one or more elements you grouped. With Grouping and Save as you removed those constraints which made the problem go away...
