BIM Viewer: open & control IFC files
Model, plans and communication in one place – in the browser, on mobile and offline
The upmesh BIM Viewer is an IFC viewer for construction projects. You upload IFC files by drag and drop; they are converted automatically and displayed in the browser or in the app without any additional software. You pin tasks, defects and change orders directly in the spatial model, so everyone involved can see what it's about and exactly where it is.
That ends the juggling of 2D plan, 3D model and coordination by email: Is the component really placed like that in the model? Which version is valid? Why doesn't the comment show up in the floor plan? The viewer answers these questions right where they arise.

Use it anywhere
The BIM Viewer runs on smartphone, tablet and desktop – without any additional software installed.
Available offline too
Tasks, defects and notes remain available without a network and sync automatically.
Intuitive to use
From the model to the information you're looking for in just a few clicks.

Load your IFC model by drag and drop
Upload your IFC files by drag and drop. upmesh converts them automatically and displays them in the browser – without additional software and without any installation on your project partner's side. The open openBIM standard ensures that models from Revit, Archicad, Allplan or Navisworks can be used.
You navigate the model freely, switch between 3D view, floor plan and bird's-eye view and retrieve object information such as materials, dimensions and classifications. Model changes are versioned automatically.
Pin tasks and defects in the 3D model
Click the spot in the model that it's about and create a ticket there: task, defect or change order – with description, photos and documents, assigned to a person responsible and given a due date. Everyone involved sees the spatial context instead of a text description.
Tickets from the model flow into the same task management as all the others: Kanban, list, table and calendar views, filters by person responsible and due date, timestamps for every change and real-time synchronization across the team.

One BIM Viewer, three perspectives
- Architecture and engineering firms: Show design details in their spatial context, simplify coordination with specialist planners and document plan changes directly in the model. Spatial pinning noticeably reduces follow-up questions.
- Site management and project control: Spot defects, capture them in the model, comment on them and document them with photos – integrated into defect management and with reporting for the client.
- Building operators: Structured handover documentation with precisely located tasks and documents. The operating phase is thus documented traceably from day one.
“The app is easy to use, so it has been adopted by all of our site supervisors and the trades we look after. We handle almost all of our communication with everyone involved in construction via upmesh, do our defect management and documentation through it, and are also happy with the versioning function of the plan management.”

Frequently asked questions
What is a BIM viewer?
A BIM viewer is a tool for viewing and using digital 3D building models without owning the original design software. In upmesh, the model and plans can also be linked with tickets, comments and documents.
How can I view an IFC file?
Upload the IFC file to upmesh by drag and drop. It is processed automatically and is then available to the entire project team; the object information from the model is preserved.
Which programs are supported?
The viewer works with the open IFC format according to the openBIM standard. This means models from Revit, Archicad, Allplan or Navisworks can be used.
Can I use the BIM Viewer on mobile?
Yes, the BIM Viewer runs fully on smartphone and tablet. You can load IFC models, navigate them and pin tickets in 3D space.
Does the IFC viewer also work offline?
Yes, the viewer can be used offline on smartphone and tablet. Changes are stored locally and sync automatically as soon as a connection is available again.
How do I pin defects and tickets in the 3D model?
Click the affected spot in the model – that's where the ticket is created. Then you add a description, photos and documents, assign a person responsible and set a deadline.
