SivaTools

Plaster takeoff for Autodesk Revit: plaster belongs to the room, not the wall — measured by the rules of your country.

Revit files plaster under the wall, yet a wall has two faces that can sit in two rooms with two different specifications. SivaTools generates a separate plaster element for every room face, accounts for openings and reveals, and takes the quantity straight from the model.

The measurement rule is selectable: Turkey (every opening deducted), NRM2 and DIN 18350 (openings under 2.50 m² measured through, reveals added). On a 22-room demo model, DIN yields 10.9% more billable plaster.

Written in native C#, supports Revit 2024–2027, runs in three languages and sells from its own site and the Autodesk App Store.
