A fix might be to introduce a new GRASS env
variable that can be set to suppress the cleaning
functions. While it would probably be trivial to
implement this, it would also break with GRASS'
basic design and the assumptions that its vector

BTW, v.transform simply transforms coordinates, it does not do any
cleaning. v.transform should actually work without topology, building
topology on the output is optional (in GRASS 7).

Hi all!
I need to use v.transform over layers that are topologically
incorrect (so they have overlapped polygons, and it is not a
problem). Of course, many elements disappear after importing the
layer, and more elements disappear after applying v.transform.
To solve this, I wrote a python

datasource has hundreds of thousands of elements and the
process takes many hours to complete.
try running v.split on the largest of the polygons.
