Cross Connector

What is it?

The Cross Connector tool finds intersections between crossing edges and creates vertices at those points. It works in edit mode and is perfect for creating clean topology at edge intersections, particularly useful for hard-surface modeling and retopology work.

Access and Shortcuts

  • Pie Menu: Edit Mode > Cross Connector
  • Operator: damtools.cross_connector
  • Modal keys:
  • Click/Enter/Space → Confirm and create intersections
  • ESC/Right Click → Cancel operation

Workflow

Basic Steps

  1. Enter Edit Mode
  2. Select edges that might intersect (or all edges)
  3. Activate Cross Connector
  4. Review warning dialog
  5. Confirm to create intersections

Warning Dialog

  • Shows warning about potential performance impact
  • Recommends saving file before proceeding
  • Displays count of edges to be analyzed
  • Option to proceed or cancel

Parameters

  • Edge Selection: Which edges to check for intersections
  • All edges if none selected
  • Only selected edges if any selection
  • Intersection Tolerance: Fixed at 1e-6 units
  • Ensures accurate intersection detection
  • Prevents false positives
  • Edge Split Threshold: Fixed at 0.01 to 0.99 range
  • Prevents creating vertices too close to existing ones
  • Ensures clean topology

Tips

  • Save your file before running on complex geometry
  • Select specific edges to limit processing time
  • Works best with non-coplanar edge intersections
  • Can be used to create clean topology for boolean operations
  • Useful for connecting crossing pipes or beams
  • The tool automatically merges vertices at intersection points
  • Progress is shown in the system console

Known Limitations

  • Only works in edit mode
  • Can be slow on very complex geometry
  • Does not handle perfectly coplanar edges well
  • Cannot create intersections too close to existing vertices
  • May have issues with non-manifold geometry
  • Heavy operations might temporarily freeze Blender
