The final label style we need to examine is the Point of Intersection label style, which plays a crucial role in alignment documentation. Navigate to the Settings tab within the Tool Space and locate the Alignments label styles folder. At the bottom of this hierarchy, you'll find two critical options: Tangent Intersection and Point of Intersection.
When you expand the Point of Intersection folder, you'll notice the absence of a golden triangle indicator. This visual cue immediately tells us that this particular label style isn't currently active within our drawing environment. However, expanding the Tangent Intersection folder reveals a station entry marked with the distinctive golden triangle symbol.
This golden triangle serves as your immediate confirmation that the Tangent Intersection label style is actively deployed in your current drawing—specifically, the label visible in your workspace. To access its configuration options, right-click on this entry and select Edit from the context menu.
The Label Style Composer window that opens provides comprehensive control over your intersection labeling. The interface is organized into several functional tabs: the Information tab displays metadata including Name, Description, and Creation details; the General tab governs Label behavior and Plan Readability settings; and the Layout tab houses the core functionality for adding Text components, Lines, Blocks, and Reference Text elements.
The most critical aspect of configuring your Tangent Intersection Label Style lies within the Contents settings, which determine what data your labels can display. Click the ellipses button to access the Text Component Editor window, then expand the Properties dropdown to reveal the full scope of available parameters.
The wealth of information available here reflects the complex nature of intersection geometry in modern civil engineering projects. Point of Intersection (PI) locations can be associated with various geometric elements including spirals, curves, and simple tangent points. This comprehensive data structure includes Extended Stations for precise positioning, complete Tangent information for approach and departure angles, and detailed Spiral One data—particularly important since contemporary highway design typically employs spiral-curve-spiral transitions for optimal vehicle dynamics.
Beyond the beginning spiral parameters, you'll find extensive curve information covering radius, delta angles, and chord data. The Spiral Two information addresses the exit spiral geometry, ensuring smooth transitions back to tangent sections. Additionally, general Alignment information provides project-level context and coordinate system references.
Any combination of this geometric data can be extracted and displayed in your Point of Intersection or Tangent Intersection labels. After selecting your desired properties, configure the appropriate modifiers for units and precision, then use the arrow button to transfer your selections to the active component list. Click OK to commit your changes to the label style.
For demonstration purposes, I'll click Cancel to preserve the existing configuration. It's worth noting that you have flexible options for data presentation: you can create a single text component containing multiple data elements, or establish multiple components each displaying specific information with custom positioning controlled through X and Y offset values.
The remaining configuration options include Drag State settings for dynamic label positioning, Leader Control for callout line management, and Text Component Control for fine-tuning label appearance during interactive editing. The Summary tab provides a consolidated view of all settings configured across the various tabs, offering a final review opportunity before implementation.
I'll click Cancel to maintain our current settings, then save the drawing to preserve our work session. In our next tutorial, we'll explore the powerful table generation capabilities that leverage the alignment labels we've configured throughout this drawing, demonstrating how to create professional documentation that automatically updates with design changes.
