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 â€˜Shellâ€™ format by idealization, and other parts are in â€˜solidâ€™ phase. According to provide fixing (connection) between subassemblies and parts, I use â€˜meshâ€™ 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.
