I assume your chainage will not always start with 0.00
I assume the chainage will not always be 10.0 increments.
I assume the frame will have a consistant bounding box.
Are you exploding the frame before you move it ?
Chainage start numbers can vary, Chainages are usually 10.0 increments, but not always.
The frame will have the same size bounding box per job, this may vary from job to job though.
Currently I am exploding before moving, but I am open to new ideas. I have 2 zip files in the lillypond, the design cross sections file is exactly how I receive it from the surveyor. The frame is not 1 entity, but lots of proxy entities
Many thanks for your help
