Infinite Curve

Infinite Curve

Infinite Curve draws a construction line long enough to behave as infinite — a reference axis for layout, mirroring, and alignment, sized automatically to dwarf everything in the scene. Rhino has no true infinite line, so the command builds one ten times the diagonal of the model’s bounding box, centered on the point you pick.

Pick the base point and the line appears; all control lives in the command-line options:

• Mode — how the direction is set:
  • TwoPoints (default) — pick a second point.
  • Horizontal / Vertical — along the reference plane’s X or Y axis.
  • Angle — pick a point to set the angle, or press Enter to use the Angle value in degrees.
  • AxisX / AxisY / AxisZ — along the world axes.
  • Bisector — pick two points and the line bisects the angle between them, the classic way to find the axis between two shoulders.
• Type — Line (centered on the base point, running both ways) or Ray (starting at the base point, running one way).
• Length — override the automatic length with an exact value.
• Reference — whether Horizontal/Vertical and Angle follow the current CPlane (default) or the World XY plane.
• Continuous — on by default: the command keeps placing lines until you press Enter, so laying down a whole set of guides is one command, not five.

The result is an ordinary Rhino line — trim it, use it as a mirror axis, or delete it when the construction is done.
