When you use the Join Geometry tool in Revit, you may notice that it sometimes just doesn’t seem to ‘work’. You do everything right, join the two adjacent surfaces – and there is still an ugly join line!
The problem is that Revit only wants to join surfaces correctly IF they are the same material. You could go into each object (floor, wall etc) and make sure all the materials are the same. However, the quick fix is shown below:
Use the Paint tool to apply the same material to the two faces you want to join.
If you have already ‘joined’ the surfaces, you need to unjoin them from each other. With walls, the easiest way to unjoin two objects is to physically disconnect the wall using grips (I do this in 3D). Revit will give you a warning – and you can then Unjoin the elements.
Now, pull the objects back together, so they are in the same plane and they meet at a clean edge.
Use Join Geometry again between the two surfaces – now that they are the same material, Revit is happy to join them properly, and it all works beautifully!
In short, Revit wants joined surfaces to be the same material before it will join them properly.
As we all know, Revit really wants you to be able to properly visualize your building. You may have experimented with Section Boxes in normal 3D views, but you can also use them in Perspective/Camera views.
Make a new Camera View.
Go to the View Properties of the Camera View, and select ‘Section Box’
To modify it, select the Section Box and then switch to a Plan View. The Section Box should still be selected, and you can modify the grips (you can modify these grips in many views).
Using this technique, you should be able to make some awesome cutaway views. These views can really help you to visualize and optimize your design.
