Now we'll construct the remaining exterior walls for Level 2 using a strategic approach that accounts for structural requirements and building code compliance. Navigate to your wall command and maintain the generic eight-inch specification, but crucially change the reference from Finish Face Exterior to Finish Face Interior. This adjustment ensures proper alignment with the interior structure. Set your base constraint to Level 2, while keeping the top constraint as Roof—we'll refine this parameter as the design develops and structural requirements become clearer.
Configure the offset to one inch, positioning it from the inside face to the outside edge of the Level 2 deck. This one-inch gap that appears as you begin drawing isn't an error—it's standard construction practice for second-floor deck installations, allowing for proper flashing, weatherproofing, and thermal bridging considerations that modern building codes require. Execute the wall placement by running it across the designated area, then bring the terminating wall inward to create a clean junction that maintains structural integrity.
Apply the same methodology to complete Level 2's wall system. Select an initial reference point within the designated area—precise placement isn't critical at this stage since we'll fine-tune positioning during the refinement phase. Extend the wall system around to meet the existing concrete wall, ensuring continuity in the building envelope. Notice the intentional gap near the curtain wall section—this strategic omission accommodates our plan to reconfigure the curtain wall as a full-height element, eliminating the need for a standard wall in that location.
The initial Roof constraint rather than Top of Parapet serves a specific design purpose: we're planning a horizontal wall element across the top level, with an additional roof deck positioned above the entire assembly. This multi-level approach requires careful coordination of wall heights. For walls requiring full-height extension, select them individually and modify their top constraint to Top of Parapet. However, certain sections demand different treatment due to the planned addition of secondary wall systems that will integrate with the primary structure.
To maintain design precision, establish a reference plane aligned with the wall face—this creates a reliable guide for completing the building shell while ensuring dimensional accuracy. From Level 1, split the curtain wall at the reference plane intersection. Remember, we'll be repositioning mullions during the detailing phase, so focus on establishing the primary structural framework first. The portion extending to Top of Parapet will create the distinctive pop-out features visible in the 3D view—these architectural elements not only enhance the building's visual appeal but also provide functional benefits such as weather protection and interior space definition.
