This video introduces the MCAD CoDesigner feature in Altium Designer, a powerful tool designed to enhance collaboration between electrical and mechanical engineers. By integrating with popular MCAD software like SolidWorks, PTC Creo, Inventor, and Fusion 360, the CoDesigner enables seamless, bi-directional exchange of PCB design data without the need for constant step file transfers. Viewers will learn how mechanical engineers can directly shape and modify PCBs within their MCAD environment, including adding mounting holes and cutouts, and then push these changes to Altium Designer. The video also covers the CoDesigner's support for the inclusion of the entire enclosure assembly to optimize layout and ensure component fit. Additionally, the tutorial highlights the capability to upload copper data for thermal and stress analysis, demonstrating the tool's potential to streamline the design process, minimize iterations, and facilitate real-time collaboration. The video guides users on how to get started with the MCAD CoDesigner by pushing a project to the Altium 365 cloud and installing the necessary extensions, showcasing the tool in action with a practical example in SolidWorks.
