Revit DB export

[MikeJarosz]

Finally got the Revit Database Exporter working. I had the notion to open the Access relation table. WOW!!!!! You have to see this!

Imagine the complete relation table. :shock: Must take up a whole wall in Waltham

Pretty simple eh? :) Most of the sorting issues we have are related to what each table uses as an ID, they are not necessarily the "name" we associate with what we see. Take Phases for example, the ID isn't the Name we use...

I would like to know how some of you are using the DB export.

For my first project with DB export, I output the wall table to Excel and sorted by height. The Revit schedule does not offer the height of walls as a system parameter, but the DB output does. Since my building is 16' floor to floor, any walls shorter than 15 feet are suspicious. Sure enough, I located walls that were dangling in midair. With the project ID, I located and corrected them.

Sure beats hunting through 3500 walls to find mistakes.

I personally run queries within Access :)

[MikeJarosz]

You are right of course, but there's all that one-to-many and many-to-one and other setup stuff for Access. For what I needed, a quick dump to XL got me instant results.

Having studied the DB file for a few days, The relation tables are ALL Revit objects, whether populated or not. I find it interesting what is excluded from the file.

> There is no location-in-space info. How they do that must be really interesting. Since the Revit philosophy has always been to de-emphasize talk about Cartesian coordinates, it might well be that Revit does not use them. LW polygons in Acad did not have a z coordinate. Instead Autodesk used a vector, forcing script writers like me to bone up on linear algebra. Could it be that Revit went whole-hog and made x and y vectors too? Or, could 3D info be buried in the families?

> There is no annotation information. I would like to see a list of detail lines and some of their properties. In Acad and earlier systems, I found this info to be useful in cleaning up junk from a drawing.

Hi all
Is there a way to export specific components thru db link , rather than exporting the whole model ?? I am working on a 400 MB file, and its taking like forever to finish the export ... thx
