What is it?
Compare two meshes takes two meshes and compares them based on their meshes' nodes. The results are visualized in a color gradient, and can also be probed in individual locations to receive a numerical readout.
While this allows comparing widely different parts at completely unrelated locations and orientations, this function is best used to learn about the before-and-after of particular processing steps such as remeshing, scaling,
To compare two meshes, Netfabb employs a module.
Comparison of original part and the simulated result of its print.
What are the key features?
- Differences are displayed using a red-green-blue heatmap on the part surface, and
- Numerical values at locations of choice available through simple point & click
- Interactive adjustment of visualization to look more closely at small differences
- Either one of the parts can act as the reference while measuring the distances towards the other
- Results do get saved in the FABBPROJECT
When should I use it?
This tool is well suited to compare before-and-after versions of the same part to learn where, and by how much, the shape has changed by actions such as repairing, remeshing, extrusion, and scaling, as well as deforming and corrective warping derived using Autodesk® Simulation Utility for Netfabb®.
TopWhere do I find this function?
From the main menu of a mesh buildroom, choose
Analyze > Compare.
It is not available for slices or while editing lattices.
TopAnything to look out for?
When requesting both directions at once, the original parts are cloned and the comparison is performed on the clones.
The algorithm requires an internal maximum of a triangle size. If it finds triangles to be too large, it will subdivide (but not remesh) them during the comparison.
The comparison results may have slightly differing minimum and maximum values, depending on which part in the comparison is the reference and which one is the measurand. This becomes particularly noticeable when the triangle resolution of the respective meshes differ significantly. It is recommended to keep triangle resolution similar, by remeshing or refining the mesh, for example.
