01 · Library
Real models with real dimensions and connections: DN, thread, flange or press. Put them in the room and they fit exactly as they will on site.




















No part with that name here — the full library in the app has 2,500+ parts.
20 of 2,500+ parts shown here. Every one of them is in the app, at real size, with its real connections.

02 · How it works

Pick parts from the manufacturers’ libraries and place them where they are installed.

Connect the ports and the pipe is laid with fittings from the system catalogue.

The schematic, the parts list and the supplier order all come from the same model.
03 · Features
Click two ports and the pipe is laid with real elbows and tees from the manufacturer’s catalogue.
Drop parts from the library into the room. They snap onto the pipe, with bolts and gaskets added.
The schematic is drawn straight from the 3D model, in blueprint style, ready to print.
Draw the walls, put a floor plan underneath or load a 3D scan of the real room.
Ask about your project — lengths, parts, quantities — and get answers from the model.
Invite a colleague and work in the same project at the same time, seeing each other’s changes.
The parts list goes to your suppliers, and their prices come back into the order.
The plant room in 3D on any phone or computer — for clients and installers, without prices.

05 · About us
Protis 3D is made by Protis, LLC. We design boiler rooms ourselves, and Protis 3D is the tool we built for that work.
That is why the library holds real parts with their real dimensions and connections, and why a project does not stop at the drawing: it carries on to the parts list, the supplier order and the installer on site.
06 · FAQ
No. Protis 3D runs in a desktop browser (Chrome, Edge or Safari). You can install it as a separate window if you like, but you don’t have to. On a phone you get the project list, the assistant and manager approvals, and clients see projects through a public link.
We switch libraries on for the systems you work with. In the app, click Request a library and choose what you need. If a part is missing, email [email protected] and we add it with its real dimensions and connections.
Yes. Invite a colleague and you both work in the same project at the same time, seeing each other’s changes and where the other person is looking. If you both change the same thing at once, nothing is lost: the other version is saved in the version history.
Create a public link. Opened on a phone or computer, it shows the boiler room in 3D, the room and the part names, but not prices. No account is needed.
A PDF report, the bill of materials as CSV, a PNG image, an IFC model for BIM and CAD software, and a 3D file as GLB, OBJ, STL or USDZ. The whole project can also be saved as JSON.
Projects are stored in your account, and the server makes a daily backup that is kept for 14 days. You restore it yourself from the version history, under Server backups. Deleting your account deletes all of its data. More in the privacy policy.
The assistant answers questions about your project. The procurement agent drafts emails to suppliers, collects quotes into the order card and follows up with suppliers who have not replied. Larger decisions, such as bigger purchases, go to the manager you name for approval.
The app is in English. Lithuanian can be chosen in the settings. Part names stay as the manufacturer publishes them.
In your profile, click Manage subscription, where you also find your invoices. The subscription runs to the end of the paid period.
