Walls Copied to a Structural Model Are Inaccurate

Walls copied from an architectural model to a structural model are not positioned properly.

Issue: When you copied a wall from an architectural model to a structural model, you changed the wall type to represent the structural core. However, the copied walls do not align with the core of the architectural walls.

This problem occurs because a copied wall is positioned based on the centerline of the wall, not the centerline of the core of the wall. If the centerline of the structural wall does not match the centerline of the architectural wall, the copied walls are not positioned properly.

Solution 1: To avoid this problem, you can do either of the following:

• Use the architectural wall type for the copied walls in the structural model.
• Do not use Copy/Monitor to copy walls to the structural model. Instead, do the following in the structural model:
  1. Create a wall style that represents only the structural core of the wall.
  2. Link the architectural model into the structural model, and pin it in place.
  3. Using the new structural wall type, manually trace new walls over the architectural walls in the linked model.
  4. Use the Align tool to align and constrain the walls in the structural model to the walls in the architectural model.

Solution 2: This solution uses the Copy/Monitor tools for a linked model.

1. Copy the walls for monitoring, as described in Copy Elements for Monitoring. During that process, set options for the walls to copy (Step 8), as described in Specify Options for Copy/Monitor.
2. If the walls have the reverse orientation (interior/exterior), select a wall and use the flip control or press the space bar to change its orientation. See Flip Controls.
3. Stop monitoring the walls.
4. Select the walls and, on the Properties palette, change the wall location line to Core Centerline.
5. Change the wall type to the appropriate structural core wall type.
6. Monitor the walls in the linked model.
