[patpat78]

Hello i have a very big problem i made my3d with pvc spec evrithing is ok 

when i generate iso there is unconected line....

the header is good ( toto.png)  and the branch not you can see turlututu pict....

evry pvc iso are the same i try with different catalog and spec but it's the same 

the problem is the GL code ( glue join) 

on steel spec evrything is ok....

i think the problem is in the isoconfig.xml i try dirrent things but no result...

the pcf are not good also i chek...

thank's
