Some walls maybe but not all and not those with windows/doors or other hosted elements that alter the wall. At least not the way that Revit looks at walls.<BR/><BR/>Further, walls can be attached to sloping faces and to the face of massing/generic models. These conditions mean that wall height is not a "simple" number. A wall with a sloped top has a varied height.<BR/><BR/>This is similar to the discussion about Room "length and width" dimensions. Easy for simple rectangular spaces but not so simple for irregular shapes. We subjectively approximate/round off such information in documentation but Revit doesn't "do" subjective well or in most cases "at all".<BR/><BR/>This is a long winded answer to say "you can't", not within what Revit offers us while using it. It won't give you an automatic value you can trust at all times. Your only way to access this information with a bit more control is by using the ODBC data export and/or via the API.Stevehttps://www.blogger.com/profile/14230364057800484763noreply@blogger.comtag:blogger.com,1999:blog-9240097.post-63533874771147554102008-09-05T19:19:00.000-07:002008-09-05T19:19:00.000-07:00Ok lets take it up a knotch.

So I can create a parameter to use a formula of Area/Length and this works ok but does not account for wall openings and reports the wrong height for walls with windows and doors. So I created a shared parameter for the wall openings so I could add back the opening area so the formula calculates properly, and so goes my question; how can you get the opening area data/parameters from the doors and windows into a wall schedule so it can be included in the wall height formula. Currently if I enter the opening areas in the shared wall parameter manually it works but I want it automated.<BR/>Any ideas appreciated, CarlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9240097.post-1122132718450699352005-07-23T08:31:00.000-07:002005-07-23T08:31:00.000-07:00echoing what Scott said, great explanation.Keep up...echoing what Scott said, great explanation.<BR/><BR/>Keep up the great work!Beau Turnerhttps://www.blogger.com/profile/10486044471796200644noreply@blogger.comtag:blogger.com,1999:blog-9240097.post-1122004784892319332005-07-21T20:59:00.000-07:002005-07-21T20:59:00.000-07:00Steve We saw this during SCRUG and now you site wi...Steve We saw this during SCRUG and now you site will go down because everybody want this info...<BR/><BR/>Love and Kisses -<BR/><BR/>- JBJim Baldinghttps://www.blogger.com/profile/18144759819413120227noreply@blogger.comtag:blogger.com,1999:blog-9240097.post-1120836100340704982005-07-08T08:21:00.000-07:002005-07-08T08:21:00.000-07:00Nice explanation!Nice explanation!Anonymousnoreply@blogger.com
