Align Floors and Walls for Proper Structural and Graphic Behavior

1. When creating a floor, use Pick Walls and lock:
   1. In Floor Sketch mode, click Pick Walls.
   2. Click wall faces you want the floor to follow.
   3. Press Tab to pick a chain if necessary.
   4. After picking, use Align (AL) and click the padlock to lock floor boundary to wall face.
2. If you drew the floor manually:
   1. Edit the floor boundary (Edit Boundary).
   2. Use Align (AL):
      • First select the wall face.
      • Then select the floor boundary line.
   3. Click the lock icon to maintain the relationship.
3. In section/elevation or 3D:
   • Confirm the floor edge meets the structural core of the wall (or as per your detail intent).
   • Later, add thin finish-only walls for continuous façade as required.

Tip

• Locked relationships between floors and walls make change management much easier: moving walls updates floors automatically.
