How to compare your scan against a CAD model and detect deviations and flaws.
The CAD comparison workflow allows users to compare scans against the idealized design intent. The result is a map of the deviations from the nominal state of the part, enabling users to visualize deviations faster and with more clarity.
Here is a video explaining the workflow.
Step-by-Step Instructions
- Import the CAD file you want to compare against using the Import tool.
- Take an ROI of the area of the scan you wish to generate the comparison from.
- Use the surface tool to generate a mesh object representing the part's surfaces.
- Use the align tool to overlay the CAD file and the mesh file. The user has manual alignment control to align to the datums they wish.
- Use the comparison tool to run the analysis based on the alignment.
- Generate visuals of the comparison.
- The range map provides a distribution of the deviations. Use the barn doors to enforce certain tolerance ranges.
- Different color maps can be applied to draw attention in different ways.
