Hi Pilou,
the nod file will not calculate multi different shapes at one time.( it will if all shapes are the same)
I have modified the nod file to take multiple paths but you will need to index thro them one at a time choosing
Pipe or Box fillets or no fillet etc.
The nod file includes the use of MO (M0_TE) new fillet curve & note nodes so I have included my latest Nodeditor.
Also included is my test file.
Please let me know of any issues.
Cheers
Barry

Correction thanks to WN the node will now do multiply paths at same time.
