When generating a 3D overview of my plan, some of my walls do not display, and are not set to invisible, or the the inner layers of my walls are showing.


The most common reason for a wall to not generate in 3D views, or if part of the exterior layer of the wall appears to be missing is that a roof or ceiling plane is cutting into the wall, preventing it from building upward.

To modify the roof/ceiling plane

  1. Locate the problem wall in floor plan view and Zoom  in on it.

    • In this simple example, a small roof plane extends into the siding and sheathing layers of a wall.

    • For illustrative purposes, the roof plane has a solid white fill.

  2. Click the Select Objects  button, then select a roof plane with an edge that touches the wall in question.

  3. Use the roof plane's edit handles to move the edge closest to the wall so that it does not extend past the wall surface.

    If the roof plane is actually locating on the floor below the wall it cuts in to in floor plan view, then you may want to select the roof plane and use the Display on Floor Above edit tool to temporarily show this roof plane on the same floor as the wall to edit it. Once it no longer cuts in to the wall, you can use the Display on Floor Below edit tool to display it back on the original floor.

  4. Create a 3D view of your model. Your missing wall should now display correctly.

  5. If the roof plane seems to keep "jumping" or "snapping" back to the original location, open the Roof Plane Specification dialog and on the General panel, check the box beside No Special Snapping, then click OK.

  6. Finally, attempt to move the roof plane again.
