I use the TC 11.2 and NX 12 integration. I have a problem about attribute of Material. I want to force the cad designers assaign Material on only NX. Because , the material attribute is setted as Modifable for the both side and it causes the missunderstand for the designers and managers. I change the modifable value on BMIDE Write to Read-only , in that case , when i create a new item from NX and assign material.Then , the attribute of Material can not change from the structure manager . Yes it works but not obtain all needs. In that case , I reopened the created item on NX and change the material , but that change is not seen on the TC<Structure Manager. How can i provide that ? Could you help me please?
