Now we'll restore the rooms we previously removed from our design. Navigate to the Architecture tab and select Room—you'll notice the dropdown menu for adding new rooms no longer displays our previously created rooms. This is intentional behavior when working in Option Set 2, as the software maintains separate room databases for each design option. Return to the main model, and you'll see our deleted rooms have been preserved and are ready for reuse—a critical feature that prevents data loss during iterative design processes.
This systematic approach enables architects to maintain consistent room types and naming conventions across multiple design scenarios while preserving data integrity. Here's where many professionals encounter a common workflow challenge: when operating in the main model rather than individual options, the room placement tool defaults to boundaries from the original design option. As you modify geometric elements, the software's spatial recognition algorithms stop identifying distinct room spaces—a behavior that can significantly impact your documentation workflow if not properly managed.
The interaction between design options and room recognition becomes more complex when switching between option sets. In Option 1, spaces that existed in the primary option may no longer be recognized as discrete rooms, appearing instead as undefined areas. This occurs because the software treats invisible geometry differently depending on your current option setting. When you switch to Option 1 view, room placement tools will only recognize the three spaces defined within that specific option set—but this recognition is contingent on having the correct option active during placement.
Understanding this relationship between view settings and room placement is crucial for accurate project documentation. When your view displays the main model option, the software reverts to the primary option's spatial definitions regardless of your intended design option. This seemingly minor detail can have significant consequences for area calculations and project takeoffs. Consider this scenario: if you're calculating the square footage of a restroom but haven't set the proper design option, your measurements will reflect the wrong spatial configuration, potentially leading to inaccurate cost estimates and construction documentation.
Let's implement this correctly by maintaining consistent room naming and numbering across our options. First, I'll switch to the main model to reference our original room assignments—rooms 209 and 210 designated for the men's and women's facilities respectively. Now, switching back to Option 2, I'll place the men's room as 209. The software will generate a duplicate value error since these room numbers already exist in our main model, but we'll proceed anyway to maintain consistency across our design options.
Following the same process for the women's room will generate an identical error message—this is expected behavior when working with parallel design options that share naming conventions. With our second-floor restrooms properly configured, we'll replicate this process on level one. Using the RM keyboard shortcut for efficient room placement, I'll assign rooms 110 and 111 based on the existing numbering sequence. Notice that the software suggests jumping to 115 to avoid duplication, but maintaining consistent numbering across options requires overriding this default behavior.
With Option Set 2 now fully configured with proper room assignments, we're ready to prepare these design alternatives for presentation. Our next phase will focus on setting up comprehensive view templates and sheet layouts, which requires strategic use of view duplication and visibility/graphic override settings to ensure each design option displays correctly in your construction document set.
