It could be interesting to be able to know (after creating a code to each element we need) the quantities contained in the 3D Project (created with personals pkt elements per example)
For a point we can obtain a total length
For a line we can obtain a total surface
And for a shape we can obtain a total volume
This information could be listed in a parameterable table inserted in the drawing and dynamically managed from the 3D project
This information could also be extracted to a .xls file
The unanswered (for the moment) question as been posted here (in french, sorry)
Thanks to all of you
