hi,

 

 

first, how to join two point dataset (both have XYZ) in one, that i have three columns, XYZ? They doesnt have any identical field..

 

 

i have point dataset with coordinates xyz and 3d polyline dataset. First and last point of polyline are coincides with points. how to assign z value from point dataset to 3d polylines?

 

 

First and last point of polyline dosent need not be at the same height.
Hi,

 

 

Use the PointCloudCombiner to join/merge the datasets.

 

You can assign the z value to the lines by a spatial test  (SpatialRelator) and z value mapping.

 

 

Itay
how can i use z value mapping? with attribute value mapper? i choose source attribute, but how can i define that use that field to assign z value?
if any points coincide with the line, or are within a tolerance, you would have to assign the z value to the nearest line vertex ( that is assuming your line has more that the start and end vertices).
