I also tried to implement the automatic placement of flanges and gaskets with a valve, by setting the Tdefault values the same for one configuration, but even there the programme doesn't selects the correct flange (nevertheless only 1 sele element of the flanges has the same Tdefault as 1 gasket and 1 valve ...) Someone experience with the use of the automatic selection of adjacent components in E3D ? Is there a manual or clean description about how to configure this ?
