I noticed that PC-DMIS lose the brackets after loops, in a feature set, so the feature constructed from it "doesn't have enough points". (PC-DMIS 2019 R2 SP2)
In the feature set, I replaced PNT1[1..15] by V1 (assignment just before the feature set ASSIGN/V1="PNT1[1..15]", and it seems to work fine... !)
Hope it's usefull for someone...
