DTM volume tool doesn't work on Bricscad V16 + recenter

Dear Bricscad users,

I have a lisp tool that makes volume calculations from two different TIN's.
It makes 3D faces out of the TIN, then it calculates a regular grid on the DTM. The volume is calculated out of the sum of the grid.
The tool works on Bricscad 15. But then I installed Bricscad 16 and Bricscad 19: the tool doesn't work on these Bricscad versions.

are there any relevant changes on the more recent Bricscad versions?
I reinstalled the VBA.
Maybe there are DLL extensions changed?
Maybe the data structure of Bricscad is changed?

Hopefully somebody knows an answer :)

Thanks!

Jonas
