Maxwell 3D users are discussing challenges related to 3D magnetic torque analysis and model importation from AutoCAD. Key issues include difficulties in transferring 3D models, as the built-in translation program only supports 2D imports, leading to flattened designs. Users have found that saving models as ACIS files (*.sat) allows successful import into Maxwell for simulations. Additionally, there are inquiries about setting up macros for automated simulations and defining material properties for complex models. Overall, the conversation highlights the need for better tutorials and support for users navigating these technical challenges.
