Hello, I am working on a project of a bridge that consists of two beam profile and attached parts to it and these sub parts are attached via rod to bridge. In my model some parts are in ‘Shell’ format by idealization, and other parts are in ‘solid’ phase. According to provide fixing (connection) between subassemblies and parts, I use ‘mesh’ command but I faced with this runtime error. Could you help me as soon as possible. you can ask me if something is missing, thank you.
