The information in this article applies to:

Chief Architect Premier or Chief Architect Interiors

Home Designer Professional


When selecting an item I receive this message:

The layer is locked. Items cannot be created or modified on locked layers. Do you want to unlock the layer?

What does this mean?


Every item in Chief Architect is assigned a layer. For example, base cabinets are on the 'Cabinets, Base' layer. When a layer has been locked, it prevents objects on that layer from being selected. New objects cannot be drawn on a locked layer, either. If you lock a layer and then attempt to draw a new object on that layer, a message box will ask you to unlock the layer.

Layers with objects that you need to see as a reference while working, but not select, are good candidates for locking.

For example:

  • Locking the “Rooms” layer can make it easier to select objects located inside of rooms.

  • Locking the “Roof Planes” layer can make it easier to select objects located under the eaves.

To determine if a layer is locked

  1. From the menu select Tools> Layer Settings> Display Options .

    In Home Designer Pro select Tools> Display Options.

  2. In the Layer Display Options dialog, notice the Lock column.

    A lock symbol in the Lock column indicates which layers are locked, preventing objects on that layer from being selected.

  3. Layers that are locked by default include:

    • Roofs, Gutters
    • Roofs, Overhang Area
    • Roofs, Ridge Caps
    • Roofs, Trim
