Disallow Wall Joins

A short time ago a request was made via this post to be able to disallow wall joins on multiple walls at once at the click of a button (http://www.revitforum.org/showthread.php/676-walls-and-joins). At the time of the post this was not possible using the 2011 API, however the ability to do this via the API has been added to the 2012 suite of products!

I posted some source code in that thread showing how to accomplish the original request and am linking to a compiled version here: https://sites.google.com/site/krispcadresources/KRSPDisallowWallJoins.zip

The work is done with these lines of code:

//loop through each wall and disallow wall joins on both ends.
foreach (Wall wall in walls)
{
    WallUtils.DisallowWallJoinAtEnd(wall,0); //beginning of wall
    WallUtils.DisallowWallJoinAtEnd(wall, 1); //end of wall
}

Obviously there is a bit of work before this point to get the collection of the walls that you want to modify.

The add-in works like this; if there are some walls already selected it will disallow joins on those walls otherwise you will be prompted to choose either all walls in the view or all in the project (or cancel).

To install the add-in simply extract the *.dll and *.addin files to the Addins folder and you're good to go. The default location for Revit 2012 products on Windows XP is: C:\Documents and Settings\%username%\Application Data\Autodesk\REVIT\Addins\2012
