Exercise: Rebuild a sharp edge

Open the file FeatureLines.3dr.

The idea is to compute the intersection and use it to reconstruct the sharp edge:

  • Launch Region Grow Plane, adjust the tolerance to 1cm and click on the left side of the pillar. Extract only the plane. Then repeat with the front side.

  • Select both planes and compute the Intersection. Show only the intersection line and the mesh. If you double click on the line, you can modify its length.

  • Select the mesh and the line, then launch the command Sharp Edges.

    • Right click in the scene to open the contextual menu: change the Representation to Flat + Wire.

    • Set the Cleaning Distance to 0.1 m.

    • Click on Preview: the mesh is modified, from 0.1 m from both side of the line, in order to respect the given feature line.

    • The edge of the pillar is now perfectly straight.
