When generating a 3D overview of my plan, some of my walls do not display.panel They are not specified as invisible, so why can't I see them?


The most common reason for a wall to not generate in 3D views is that a roof plane is cutting into the wall, preventing it from building upward.

To modify the roof 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 planes' edit handles to move the edge closest to the wall so that it does not extend past the wall surface.

  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.  On the General panel, check the box beside No Special Snapping, then click OK.

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