i have installed.i want to assign material to part.But since only nylon material is available and no other material like abs etc are available .so how can i resolve this issue?
You only see NYLON because you have not installed the MW Data files which need to be downloaded from the SPLM FTP server. Once you're logged into the Downloads page these can be found under "NX > Product Updates > Moldwizard". Download and unzip the data file and install it per the README instructions, including setting MOLDWIZARD_DIR to the correct location.
More information can be found in the online documentation.
