The Zebra Analysis command displays alternating black and white stripes on a body to help you analyze the curvature of a surface in Fusion 360.
Select the bodies to analyze.
Select a direct to display the stripes on the body.
Specify the number of stripes to display on the body.
Specify the transparency of the stripes displayed on the body.
Check to lock the stripes in place as they appear on the body.
Check to increase the display quality of the stripes on the body.

The Zebra command visually evaluates surface smoothness and continuity using a stripe map.
The Zebra command is one of a series of visual surface analysis commands. These commands use NURBS surface evaluation and rendering techniques to help you visually analyze surface smoothness, curvature, and other important properties.
- Set the stripe direction, size, and color.
Stripe size, stripe color.
Display surface isocurves and edges.
Open Polygon Mesh Options to change analysis mesh density. Increasing mesh density improves the analyzing accuracy.
Select more objects to analyze.
Remove selected objects from the analysis.
Interpreting the stripes
Position only (g0).
Tangent matches; curvature does not match (G1)
Position, curvature, and tangency match (G2)
If, when you use the Zebra command, the selected objects do not already have a surface analysis mesh, an invisible mesh will be created based on the settings in the Polygon Mesh Options dialog box.
The surface analysis meshes save in the Rhino files. These meshes can be large. The RefreshShade command and the Save geometry only option of the Save and SaveAs commands remove any existing surface analysis meshes.
To properly analyze a free-form NURBS surface, the analysis commands generally require a detailed mesh.
The ZebraOff command turns off zebra analysis and closes the Zebra dialog box.

Analyzing shapes through Zebra Lines
The Zebra command helps you visually analyze surface smoothness and curvature.
Consider that the zebra stripes jump sideways as they cross the connection from one surface to the next or if the two surfaces touch, but have a twist or crease at the point where the zebra stripes jag. This indicates G0 continuity between the surfaces.
If the stripes line up as they cross the connection but turn sharply at the connection, means that the position and tangency between the surfaces matches. This indicates G1 continuity between the surfaces. Surfaces that are connected with Fillets usually display this behavior.
If the stripes match and continue smoothly over the connection, this means the position, tangency, and curvature between the surfaces match. This indicates G2 continuity between the surfaces.
- If the zebra stripes (curves) have deflections, it indicates surfaces are in G0 continuity
- If the zebra stripes (curves) turn sharply (curves are in G0) it indicates surfaces are in G1 continuity
- If the zebra stripes (curves) match and flows smoothly (curves are in G1) it indicates the surfaces are in G2 continuity
In the above images, conditions 1, 2 and 3 illustrate the the G0, G1 and G2 continuity respectively.

How to Adjust the Zebra Analysis in Rhinoceros 3D
Zebra analysis is a visualization tool in Rhinoceros 3D that helps to evaluate the continuity and smoothness of a surface or a set of joined surfaces. It displays a series of alternating black and white stripes on the surface, which show how the surface is curving in different directions. The stripes are oriented perpendicular to the direction of the surface curvature and change direction at points where the curvature changes.
If the Zebra stripes in Rhino appear jagged, it may be due to the mesh settings not being set to a high enough resolution. Here are some steps you can take to address this issue.
Select the Adjust Mesh option in Zebra Analysis.
Density: controls the number of mesh polygons used to generate the Zebra stripes. Higher values result in smoother stripes, but can also slow down performance.
Refine: subdivides the mesh polygons to improve accuracy of the stripes, but can also increase the mesh complexity and slow down performance.
Max Angle: controls the maximum angle between adjacent faces in the mesh. Smaller angles result in smoother surfaces but can also increase mesh complexity and slow down performance.
Maximum Edge Length: sets the maximum edge length of each mesh face. A lower number will create an accurate dense mesh but can also increase mesh complexity and slow down performance.
Once you have finalized the mesh setting, you can see high quality Zebra analysis.
Bug: Sometimes the Zebra mesh preview will show you an accurate results but the effect disappears once the options are confirmed. To resolve this, try exploding and joining the surfaces again. This will generally trigger the analysis to recalculate mesh.

All About Zebra Stripes
With zebra stripes you can easily see any defects or imperfections in the surface, but you can also instantly identify the type of boundary that exists between two adjacent surface.
- Contact: Zebra stripes match at the boundary
- Tangency: Zebra stripes match at the boundary, but there is an abrupt change in direction
- Curvature Continuous: Zebra stripes continue smoothly across the boundary. Curvature continuity is an option when creating face blend fillets.
As you can see zebra stripes is a very powerful tool that can be used to quickly understand the details of the quality of your models. If a high quality, good looking surface is what you’re looking for, zebra stripes is the tool for you.
