Hello guys

i'd like to create a mesh (mainly along sidewalk and road surface) while forcing the triangle creation to stick to pre-defined breaklines.
I really would like to do this in Metashape directly, but there doesn't seem to be a way to include breaklines into the meshing process.
And even if it would work in Metashape another issue comes the "rounded edges" "photogrammetric curve"
Two questions related to this:
1) Do you know any improvements of Metashape with regard to this?
2) Do you have any recommendations for any other workflow?
Thanks a lot, guys.
Alex
