Direct Answer
Tekla Structures Multi-User allows multiple detailers to work simultaneously on the same model through a shared server — similar to multi-user CAD. Each user checks out sections of the model, makes changes, and writes back. Alternatively, Tekla Model Sharing (cloud-based) allows geographically distributed teams to share model packets asynchronously without a dedicated server.
Full Explanation
For integrated detailing teams, Tekla Model Sharing is the most common approach. The lead detailer's server hosts the master model. Team members download a model packet, work offline, and push changes to the cloud. The lead detailer reviews and merges changes on a defined schedule. This workflow allows teams across time zones to work in parallel, which is a major advantage for fast-track projects. Model conflicts (two users editing the same object) are flagged for manual resolution.
What This Means for Your Shop
When working with a team across multiple offices or internationally, confirm it uses Tekla Model Sharing or a similar coordinated workflow. Fragmented models (separate Tekla files merged manually) are prone to errors at the seams between modeling zones.
Common Mistakes
Each detailer working in a separate Tekla file and manually combining at the end. This process is error-prone and defeats the purpose of a single 3D model. Insist on coordinated model sharing from the start.
Recommended Process
At project kickoff, establish who hosts the master model, what the packet sharing schedule is, and how conflicts will be resolved. Assign modeling zones to each team member to minimize concurrent edits of the same objects.
