Zysnor Revit QTO

Who it is for

• Quantity takeoff engineers and estimators.
• Draftsmen moving from AutoCAD to Revit BIM.
• Site engineers who need a quick 3D view for a client.

The problem it solves

• Modelling from DWG drawings in Revit by hand takes a lot of time.
• Manual quantity takeoff is slow and easy to get wrong.
• Clients and consultants want quantities checked against the approved DWG, not against drawings made in Revit.

How it works

1. 01

   Choose a floor and attach drawings

   Pick the Revit level, then attach one drawing per slot: walls, flooring, ceiling and wall finishing. Each DWG is linked at its original coordinates.

2. 02

   Map layers and confirm the legend

   Match each CAD layer to an element type, and confirm what each legend code (W1, W2, F1, C1…) means before anything is applied.

3. 03

   Build the model

   Walls, doors, windows, floors, ceilings and finishes are created inside named Revit steps that you can undo. When a height or finish is unclear, the plugin asks you instead of guessing.

4. 04

   Export and verify

   Export the takeoff to Excel, with a unique ID on every line, and save a copy of the approved DWG named “original name – QTO Markup”, with colour hatches and tags on separate layers.

Features planned for the first release

• Step-by-step wizard for each floor.
• Layer mapping that you can save and reuse for each project.
• Legend mapping table (W1, W2… to materials) that you confirm.
• Finishes on the correct wall face, with their heights.
• Quantities per element: length, height, area and count, with door and window openings deducted.
• Excel output with ID, code, description, unit, quantity, level and room on every line.
• Checking markup on a copy of the approved DWG. With the QTO layers off, the client sees the original drawing.
• Model check report for missing walls, unassigned faces and rule breaks.
• Progress bar and Cancel on long tasks, so Revit does not freeze.
• An error log you can send to support.

Planned for later versions

Each feature is released only after it passes testing in Revit.

• Reading legends, ceiling levels and title blocks automatically.
• Room rules, for example porcelain tile in washrooms with no paint or plaster.
• MEP from HVAC, firefighting and electrical drawings: ducts, pipes, cable trays and fixtures.
• Quick Room: a 3D room with elevations from site measurements and chosen fixtures.
• A materials library, and comparing a new drawing revision with the last one.

System requirements

Operating system

Windows

Revit

Autodesk Revit 2021 and later (planned). The tested versions will be listed at release.

AutoCAD

AutoCAD installed on the same computer, used in the background to read legends and title blocks.

Internet

Needed for sign-in and licence checks in the version offered to customers.

Version

Not released yet · In development

Licensing

Licensing and pricing will be announced at release.

Quantities only

The plugin reports quantities. It does not include material prices or cost estimates.

Your drawings and data

The approved DWG is never modified; all markup goes on a copy. Planned for the release version: only short pieces of text, such as legend text, layer names, codes and levels, are sent to Zysnor to produce results and protect the licence. Full drawings are never sent, and title block details such as client and project names stay on your computer.
