Upgading to 2009 WU-1, We get errors!!

[Baldwin_4-6-0]

We have a project with 0 Review Warnings in RAC2008-SP3, but when we go to upgrade we get 7 Review Warnings saying we must delete those 7 doors in order to continue, (and we can't tell where the are). And after that, the file has 6 stupid Review warnings about the line being slightly off axis, blah blah.

Anyone else experience odd stuff like that?

I had the same thing happen to me on the original 2009 build.

I had to delete a handful of sweeps and then unjoin some other stuff... errors i dont think i had in 2008. I just chalked it up to 2009 being a more sophisticated error detection tool...
That's just my positive thinking. I deleted what i had to and moved on.
Still dont know where those trouble sweeps were...

I don't think I should have to "worry" when I upgrade a project, but I do!!

The other thing is, the upgrade took some modeled roof hatches off the roof and placed them 16 feet into the air? What the ???

Maybe the next Service pack will be better. arghh.

Baldwin,

The upgrade to r2009 regenerates almost every element in your model potentially bringing some old lurking problems to light.

Unfortunately our error displaying UI is not perfect thus the some of the elements are not easily displayed. If you really care about them, make a note of their ID-s (reported by the error dialog), open your file in the previous (r2008 ) version and use the "Tools->Select by Id" command.

As for the "lines being slightly off axis" warnings, those conditions may cause ugly problems later if those lines are referenced in some later calculations. (Think of them as a needle in your tire. You are usually better off fixing it before the trouble happens.)

Just one example of a problem:


You have two almost parallel lines you imported from a dwg file that are off by 0.0001" and have an angle of 179.9999 degrees (I had seen that happen!). If you picked them as room separation lines, your room boundary may have to find their intersection point which could be pretty far from either of the line ends due to the "slightly off axis" nature. Still, the room could be kind of ok. However, in r2009 say you turned on room volume computations which makes a 3d shape out of the room and subtracts a roof from it. Now the incorrect corner may result in a tiny sliver of room that when exported to heat analysis acts as a heat source due to being exposed to the sun, spoiling the analysis data. Or the 3d subtraction may simply fail due to numerical problems.

About your last problem with roof hatch being 16 feet in the air, I am pretty sure that if our QA had found such case, the release would have been delayed to fix it. So if you could be kind enough to send your model to Revit support, we would have a chance to correct the code.

Tamas;
I agree with you on the "off axis" lines regarding Model Lines. Maybe an annoying message, but probably necessary for the reasons you state. However, you get the same kind of Warning on Detail Lines. I can't imagine any reason I would care if a Detail Line is a little bit crooked. It should not be referenced by anything else.
I have two suggestions.
First, and simplest, is to ignore the "off axis" for Detail Lines.
Secondly, and I realize this may not be simple to implement, it would be nice to have some means of flagging a Warning message as acceptable. For instance, we've been doing a lot of buildings lately that have curves and the walls are prepedicular to the curve. Some walls ARE slightly off axis, and are supposed to be. Flagging those as acceptable would allow me to focus on the items that really are in error.

Yes, it's the detail line version of the warning, and the 2008 version does not have any warnings, including the lines being slightly off axis warning..so why does it create them on the upgrade?

[samov]

I think they should make it impossible to create these lines... I see them created ONLY as a backward compatibilty with dwg cad drawings... but there is NO real reason to have lines that are 100th of a degree accurate. DWG drawings are dirty enough as it is... we should not have them dirting revit models too...

In reality you should not be able to create anything that is either that small or accurate... we are designing buildings, not nano-sized tranzistors....
