Exercise: Compute best shapes from clouds and polylines

Beside the creation of geometric shapes by clicking points or by directly defining its parameters, you can extract a shape by fitting it to existing objects (meshes, clouds, points, other shapes...).

The following exercise will illustrate how to extract shapes and their properties from potentially measured point clouds.

Open the file AlignOnRef.3dr.

Show only the folder BestShapes. then compute each corresponding best feature. For instance, select the line and open the dialog Best Line:

  • You can eliminate noisy points by using the parameter Eliminate worst points: eliminate 10 points.

  • You can lock some parameters: lock the direction to Z.
