Annotating Piping Plans: Tagging Pipes and Adding Notes

In this comprehensive walkthrough, we'll master the annotation process for piping plans using industry-standard practices. Let's begin by navigating to our Level 1 piping plan, where we'll establish a clean foundation for our technical documentation.

Our first step requires removing the preliminary building sections we created earlier. These initial sections served their purpose during the design phase, but now we'll rebuild them with precision when we reach the dedicated building sections portion of our annotation workflow. Select these sections and delete them, then click OK to confirm the removal.

With our workspace cleared, we'll implement a systematic approach to pipe tagging—a critical component of professional piping documentation. Navigate to the Annotate tab and locate the "Tag by Category" function. This powerful tool will streamline our annotation process significantly.

The Tag by Category feature operates through intelligent hover detection. As you position your cursor over different model components, the system automatically generates appropriate tags for each element. For instance, hovering over a branch line produces a comprehensive pipe tag displaying essential specifications: "1½", Schedule 10, 12 feet above finished floor." This standardized format ensures consistency across all project documentation and meets current industry requirements for technical drawings.

Before proceeding with mass tagging operations, verify your tag configuration. Click on any existing pipe tag, then examine the Properties panel to confirm you're using the correct tag family: "Fire Sprinkler Pipe – Schedule 10, Pipe Size Tag – Schedule 10." This verification step prevents inconsistencies that could compromise project documentation quality.

Now we'll execute the systematic tagging of all pipes on our Level 1 plan. Return to Annotate > Tag by Category and begin the comprehensive tagging process. Note that we'll exclude armover piping from individual tagging—instead, we'll address these components through strategic notation, which proves more efficient given their quantity and standardized nature.

During the tagging process, strategic placement becomes crucial for maintaining drawing clarity. Position tags to avoid obscuring sprinkler locations, valve symbols, or other critical infrastructure elements. When tagging main lines, select locations that provide clear visibility without cluttering the drawing. You may need to adjust tag positions after initial placement to optimize readability.

Focus your tagging efforts on pipes serving multiple sprinklers, as these will invariably exceed 1" diameter and require Schedule 10 designation. The 1" armover pipes, while numerous, follow standardized Schedule 40 specifications that we'll reference in our general notes section rather than individual tags. This approach maintains drawing clarity while ensuring complete specification coverage.

Maintain flexibility in your tagging sequence—the order of tag placement matters less than comprehensive coverage. However, establish a systematic pattern to avoid omissions. For complex main line runs, consider multiple tag placements at direction changes or significant length intervals. This redundancy aids field personnel during installation and inspection phases.

As you progress through the tagging process, regularly assess tag placement from a holistic perspective. Some main lines may benefit from tags at both ends, particularly where they interface with different building zones or structural elements. This comprehensive approach ensures that field technicians have immediate access to pipe specifications regardless of their position on the drawing.
