Help my walls show up on the plan but not the 3D View!

A common problem. So common I decided to write a checklist to follow if an object doesn't show up in a Revit view. This list is not exhaustive, but covers most of the problems we've had so far.

Examine View Properties

• Check view range
• Check region cut
• Check view distance
• Check view co-ordination – use coordination view if in doubt. Remember to mouse over view to cause it to redraw.
• Check view detail fine/coarse – Use fine if in doubt
• Check current render type - hidden line/shaded/realistic. Some materials only display properly when actually rendered.

Examine Object in View

• Check object visibility settings – Ensure no settings are overridden.
  
  • By Element
  • By Category
  • By Filter
• Check object override settings – Ensure no settings are overridden. In particular ensure you are checking the correct pattern. Surface Pattern is different to Cut pattern.
  
  • By Element
  • By Category
  • By Filter
• Examine and remove extra paint applied to object. If in doubt, use the remove paint tool anyway just to ensure nothing is painted on.
  
• Switch view to “Reveal hidden elements” mode, as it may be not visible.
  

Examine Material used

• Examine Material
  
  • Examine use-render appearance
• If surface fill pattern, check draft/model type

Examine Object Properties

• Examine if using correct external/internal layers
• If it's a wall, check its orientation, if the internal is facing out, then the wall will need to be flipped so the external layer is outside.
• Check which phase the object is in.

Check Revisions or Work Set

• Check which revision or work set the object is in; ensure your current view matches.
