Hi, I have 2 sets of features (terrain and buildings) that derives from Sketchup source file in coord WGS84 and are read via FeatureReader in to the workspace. When I combine the two features via FeatureHolder and look at visual 2D preview they both have the correct geo-location, . But if I switch over to visual 3D preview the building features seem to get an offset? If I add a Reprojector transformer (having the source coord read from feature WGS84, and destination coord to SweRef 99-18-00) they both line up in both 2D and 3D preview. Any ideas why this is happening? Please see attached image. Thanks.

As an add on... as a kind of work around I added a CenterpointReplacer, since the definition of the 2 features derives from a 2D polygon frame, and calculated the x, y difference between the two Centerpoints and applied the result the the Offsetter transformer.
