As expected, this approach won't work here. In technical design, straightforward solutions rarely apply universally—we'll need to revisit these connections with a more nuanced strategy.

Here's a professional workflow tip I've developed over years of complex system design: when juggling multiple design challenges simultaneously, use visual reminders to maintain focus without losing momentum. Navigate to Annotate > Revision Cloud and place a marker around problematic areas. This simple technique prevents critical issues from slipping through the cracks during intensive design sessions, especially when working under tight project deadlines.

Let's test connectivity on this section. Excellent—we can proceed with the one-inch specification here. This uniform sizing will maintain system pressure consistency as we advance to the next line segment.

Now comes the critical part: when making bulk adjustments, exercise precision in your selections. As long as you avoid selecting the branch line inadvertently, the process remains straightforward. Carefully deselect the sprinkler component first, then apply the one-inch specification. This methodical approach prevents cascading errors that can compromise entire system segments.

Perfect execution there, though I notice we've inadvertently selected those sprinkler heads. No cause for concern—this actually demonstrates proper error recovery protocol. Simply deselect all sprinkler components using the filter menu, which efficiently isolates your intended modifications.

Here's where real-world project management intersects with ideal design principles. While best practice dictates single-sided outlets for optimal flow dynamics, experienced professionals recognize when strategic compromises serve the broader project goals. In this instance—facing deadline pressures that demand rapid deployment—we'll implement dual outlets. This pragmatic decision balances engineering excellence with business realities, a skill that separates senior designers from purely theoretical practitioners.

We'll maintain this configuration and proceed. Sometimes professional judgment means recognizing when "good enough" serves the project better than pursuing perfection at the expense of deliverability.
