Intersecting walls

[h.s.meijering]

Hello,

I have a problem, after some modeling some of my new drawn walls became longer and started intersecting with my exterior walls. What am I doing wrong. See the attachment!

Thanks

You aren't doing anything wring. Revit will try to connect the walls and clean them up. You can prevent this by selecting the wall, finding the blue grip at the end of the wall and right clicking on it. Select 'disallow joins' and you should be able drag the wall end or align it to the inside face of the other wall.
