Revit roof geometry joining. The forgotten options. You can only modify this setting if the detail level of the view is coarse this technique is useful if you have a lot of walls removing the tedious process of manually adjusting the join and boundary of each individual wall. Use the join geometry tool to create clean joins between 2 or more host elements that share a common face such as walls and floors. You cannot join a roof to more than one top face of another roof.
The third and final technique to control the wall joins is to use wall join display in the instance properties of the view. 3 adjust wall join display in view properties. It will join in the wrong order and you will need to use the drop down menu next to join to switch the join order. You can also use the tool to join hosts and in place families or hosts and project families.
You can join roofs to other roofs or walls or unjoin them if they were previously joined. This is a general. The joined elements then share the same line weight and fill. We are around the back side of the building now select this tool in the geometry tab called join unjoin roof.
The wall must be attached to the target roof and the target roof must be a footprint roof. I ve zoomed in closely here hoping that you can see.
