i have two sets of data: a lidar point cloud and dgn files with some 3D lines/polylines.

How can i check if these lines are close (lets say within 4 m from surface)/under/touches the surface created with pointcloudsurface?

Hi @loganj,

Did you try to use the transformer NeighborFinder?

Thanks,

you could drape the vertices (Id the vertices) of the lines on the surface.

Extract coordinates of the draped vertices.

Merge them to originals by ID.

Calculate distance using these coordinates. Test if <4m
