What is a ʼPointʼ object in Rhino?

Short Answer

In Rhino, a point object is a single, zero-dimensional reference used to mark an exact location in 3D space. The most common way to create one is with the Point command, typically for snapping, construction, or annotation workflows. A Point object has no length, area, or renderable thickness.

What You Need to Know Before

Warning: Point objects are easy to confuse with point-editing grips or control points, but they are not the same thing in Rhino. If you select the wrong type, snaps, exports, and downstream modeling steps may fail or behave unexpectedly.

How to Create a Point Object in Rhino

• Command: Point

• Shortcut: Point

• Quick Steps:

  1. Run Point from the command line, or go to Curve menu > Point Object > Single Point.
  2. Click in a viewport to place the point, or type exact coordinates for precise placement.
  3. Press Enter to finish, and keep Project toggle set correctly if you need the point placed on the active construction plane.

Variables & Settings

• Key Setting: Project toggle in Osnap/status bar or command behavior

• Expert Setting: When Project is enabled, the picked location can be projected onto the active CPlane instead of keeping the true 3D picked height. This is a common source of misplaced Point objects in multi-viewport work.

Why it Fails

• Cause 1 (Geometry): The point is created on the wrong CPlane or projected to the active construction plane, so its Z position is not where you expected.
• Cause 2 (layers/Locks): The current layer is locked, off, or later hidden, making the Point object seem missing or uneditable.
• Cause 3 (Command/Logic): You selected a control point or edit point instead of a real Point object, so object-based commands do not work as intended.

Quick Fix & Best Practice

• Quick Fix: Turn off Project before running Point, then use What to verify that the result is a true Point object at the correct coordinates.
• Manager’s Verdict: Use Point objects for exact reference locations, snaps, and setup geometry, but avoid relying on them as visible deliverable geometry since they are mainly construction aids.

FAQ

Is a Point object the same as a control point in Rhino?
No, a Point object is separate geometry, while control points are editing handles for curves and surfaces.

Can a Point object be snapped to by other geometry?
Yes, Point objects are commonly used as snap references in precise modeling.

Can Rhino render a Point object as visible solid geometry?
No, a Point object is only a location marker unless displayed through point style settings.
