Sibe is a cloud-based platform designed for product data management and 3D collaboration, specifically tailored to assist small and medium-sized mechanical engineering teams that utilize SolidWorks CAD software in effectively managing, sharing, reviewing, and controlling intricate design data and workflows without the need for conventional servers, VPNs, or extensive IT infrastructure. The platform offers features such as version control, check-in/check-out capabilities, and structured revision and approval workflows, along with file history tracking, all integrated through a native SolidWorks add-in, which enables engineers to work concurrently on designs while preventing accidental overwrites and maintaining a thorough audit trail of modifications. Additionally, Sibe provides a user-friendly browser-based interface that allows both users and external stakeholders to view, comment, and annotate 3D models and 2D drawings from any device without the need to install CAD software, and it facilitates secure external sharing with controlled access, allowing for unlimited free web visitors so that partners can easily review designs without requiring any specialized software. This flexibility not only enhances collaboration but also streamlines the design process, making it more efficient and accessible for all involved parties.
