Triangle Reduction

The Triangle Reduction command is used to reduce the number of triangles in the part mesh.

In the 3D Sprint application, parts are represented as triangle-meshes. Triangle Reduction can reduce the file size, or the complexity if the part has a very dense mesh. This will improve the performance of 3D Sprint while manipulating 3D parts.

Note: (NextDent 5100 Printer) Click Simple UI to switch between the simple and the advanced User Interface. In the Simple UI, only the tools for minimum workflow are visible.

Note: Using triangle reduction needs caution as it can change parts’ surface to lose their detail feature like below image.

Note: To view the triangle density in the Part Properties, toggle Edge shading mode in the View Overlay and select the part.

 

1. In the Prepare tab, click Triangle Reduction.

2. Select one or more parts.

3. Select Maximum Allowable Error to set the overall accuracy of the resulting part mesh. This sets the maximum error that will be allowed.

   0.1mm	1mm

4. Enter values in Triangle Count or Remaining Ratio to target a specific number of triangles or a percentage of triangles to keep.
   .

   Note: The Maximum Allowable Error takes priority. If the maximum error is not achievable, the final number of triangles or percentage will be higher than the target value.

5. Click Apply. Repeat if additional reduction is necessary.

   

6. Click Close to complete the commend.

7. Inspect the final result using Edge display in the View panel.
