When dealing with a wall that transitions from interior to exterior within the same location, you'll need to strategically split this element to maintain distinct wall types on each side. Since this wall uses the center line as its location reference, any modifications will extend equally in both directions—a critical consideration for maintaining proper alignment throughout your model.
Before proceeding with the split, verify the wall's exterior face orientation using the flip toggle indicator. This visual cue consistently identifies the exterior face, and in this instance, it's incorrectly positioned on the interior side. Correcting this orientation now prevents additional adjustments later and ensures your wall type changes align with the intended exterior direction—a best practice that saves significant time during the modeling process.
Initiate the split operation while ensuring the "Delete Inner Segment" option remains unchecked, as your objective is segmentation rather than deletion. Position your split point approximately at the face where the wall type transition should occur. The software's intelligent snapping will guide your cursor to logical break points, typically aligning with the exterior face boundary for optimal results.
With your wall segment selected, update the wall type to "Exterior Brick on Metal Stud." Take advantage of the "Most Recently Used Types" feature, which streamlines your workflow by providing quick access to previously selected wall assemblies. This functionality becomes increasingly valuable on complex projects where multiple wall types are frequently applied throughout the model.
The equal growth on both sides will inevitably create alignment issues with adjacent walls. Address this using the Align tool, accessible from the Modify tab. This precision tool ensures perfect face-to-face alignment between wall segments, maintaining the geometric integrity essential for accurate construction documentation and quantity takeoffs.
Execute the alignment by selecting the Align tool, then clicking the reference face followed by the face requiring adjustment. The walls will automatically align, creating a seamless transition. While joint conditions may appear imperfect at this stage, address these after completing modifications to the opposing side for optimal results.
Repeat the splitting process on the remaining segment using the Split command (keyboard shortcut: SL for efficiency-focused users). Maintain the same methodical approach: verify exterior face orientation, split at the appropriate transition point, and create two distinct segments ready for individual wall type assignment.
After confirming proper exterior face orientation, apply the Brick on Metal Stud wall type and utilize the Align tool (keyboard shortcut: AL) to achieve precise positioning. This systematic approach ensures consistency across all wall segments while maintaining the geometric relationships essential for professional-quality models.
The final step involves optimizing wall joins using Revit's Wall Joins tool to create appropriate connections between your three wall segments. Begin by adjusting your Detail Level from Coarse to Medium, which reveals the individual layers comprising each wall assembly. This enhanced visibility is crucial for making informed decisions about joint conditions and layer interactions.
Consider switching to Thin Lines view to eliminate visual clutter from heavy line weights, allowing clear assessment of all wall layers and their relationships. From the Modify tab, access the Wall Joins tool and hover over the intersection point. The software will display a selection box indicating the available join area.
Select the wall join to access the Previous and Next navigation options, which cycle through available join conditions. Each option represents different layer interaction approaches, from simple overlaps to complex interlocking arrangements. Evaluate each condition against your project's construction intent and detailing standards.
The optimal join condition for most projects typically maintains material continuity while respecting the structural hierarchy of your wall assemblies. Apply the same systematic evaluation to the opposite intersection, ensuring consistent joint treatment throughout the wall assembly. This attention to detail distinguishes professional-quality models from basic geometric representations.
