What to Do if You Experience Flickering and Uneven Coloring on a Revit Model Surface
If the surface of your Revit model shows uneven coloring, blurry graphics, triangles, or other shapes, and flickers during dynamic viewing or zooming, you are likely encountering a common display issue.
For instance, when overlapping floor areas are zoomed in and out, you may notice the colors shifting or flickering.
You might see these effects under the following conditions:
- When patterns or colored surfaces overlap
- When faces have varying colors, such as when the visual style is set to “Coloring,” “Authentic,” or “Consistent Color”
- When using the “Hidden Line” visual style during element selection
- When two floor slabs or two walls are modeled directly on top of each other
- When a wall and a floor share the same face
Flickering is most common during dynamic navigation or when zooming in and out with visual styles like “Coloring,” “Authentic,” or “Consistent Color.”
Cause: This issue arises when two surfaces occupy the exact same plane (coplanar surfaces) but have different colors or patterns. The software cannot determine which surface should be displayed on top, causing both surfaces to render simultaneously and creating visual clutter.
Solutions: To resolve this, try one of the following approaches:
- Use the “Connecting Geometric Shapes” tool to merge overlapping shapes into a single entity.
- Modify the floor sketch so its edges do not lie on the same plane as the walls.
- Adjust the wall geometry to avoid coplanar surfaces—for example, slightly offset overlapping planes from each other.
