Hello,

QgsGeometr.

I have problem with 3d result of intersection. I intersected 2D line string
with 3d Polygons. Outpu line string is in 3D. But asPolyline() method on
line string return only 2D points, is it possible to return also array with
3D points?

intersection = ingeom.intersection(intersectgeom3d)
intersection.exportToWkt()

intersection.asPolyline()
[[(661938,7.45069e+06), (661939,7.45069e+06), (661939,7.45069e+06)],

(661906,7.45071e+06), (661907,7.45069e+06), (661907,7.45069e+06)]]

Is it possible to handle with this? I need list of geometry to make some
changes in this list.

My next question: for what is intersect returned 3D geometry and it is not
possible to handle with this geometry in next code.
