Z

Hi guys,

I'm trying to offset lines (SHP) with z-value geometry using OffsetCurveGenerator. I have two attributies to offset roads at left or right site of the road. It works ok, by I'm loosing information about z-value which is significant becouse I'm trying to get flat surface of the road (the second phase is to update DTM).

Function @Buffer(@Value(RBuffer),22.5, RIGHT_SIDE_ONLY) gives the same resoult.

Any idea how to offset road but keeping z-value?

 

Thanks for the help,

What you can do, is storing the Z values upfront and update them afterwards. However, you should take into account that extra vertices might be created when offsetting your line.
