Can I see through my solid objects using ʼX-Rayʼ mode in Rhinoceros 3D?

ByCADbrief Staff

Short Answer

Yes — in Rhino 3D, you can see through solid objects by switching the viewport display mode to X-ray, which is the most common professional way to inspect interior geometry without changing the model itself. This works best directly from the viewport display mode menu. Limitation: X-Ray is only a visual display aid, not true sectioning.

What You Need to Know Before

Warning: x-ray mode can make overlapping surfaces, bad joins, and internal duplicate geometry harder to read because everything becomes semi-transparent at once. On heavy models, it can also reduce viewport performance and make object selection less reliable.

How-to

  • Command: SetDisplayMode

  • Shortcut: No default shortcut

  • Quick Steps:

    1. In the target viewport, click the viewport title drop-down (for example, Perspective) and go to Display Mode.
    2. Choose X-Ray from the list.
    3. If needed, open Options > View > Display Modes > X-Ray and adjust a setting like object transparency or edge visibility.

Variables & Settings

  • Key Setting: X-Ray display mode options

  • Expert Setting: In Options > View > Display Modes > X-Ray, you can control visual behavior such as transparency, shaded appearance, and edge display. Turning edges on usually makes internal parts easier to read, while higher transparency can help when inspecting nested solids.

Why it Fails

  • Cause 1 (Geometry): Closed polysurfaces with dense internal faces or overlapping objects can become visually cluttered, so internal details are still hard to distinguish.
  • Cause 2 (layers/Locks): If the needed objects are on hidden, off, or locked layers, X-Ray will not make them easier to inspect or select properly.
  • Cause 3 (Command/Logic): X-Ray is only a viewport display mode; it does not cut geometry, expose hidden intersections, or replace commands like clipping or sectioning.

Quick Fix & Best Practice

  • Quick Fix: Use SetDisplayMode to switch the active viewport to X-Ray, then turn on visible edges in Options > View > Display Modes > X-Ray for clearer internal reading.
  • Manager’s Verdict: Use X-Ray for quick visual inspection during modeling and coordination, but avoid relying on it for precise review. For production checks, use clipping planes or section workflows instead.

FAQ

Can X-Ray in Rhino 3D help me select hidden objects?
Yes, but selection can still be difficult in crowded or overlapping geometry.

Is X-Ray the same as Wireframe in Rhino?
No, X-Ray keeps shaded objects semi-transparent, while Wireframe only shows edges and curves.

Can I make only one object transparent instead of the whole viewport?
Yes, but that is typically done through object display or material/transparency settings, not the X-Ray display mode.
