Questions

What teams ask before turning on AutoCAD.

Contact the billing team

Does Tatha Vastu open DWG files?

No. AutoCAD's data extraction writes the lengths and areas to Excel or CSV, and Tatha Vastu imports that file.

Are drawing quantities billed as they are?

No. They arrive as draft measurement rows. A billing engineer checks them against site before approval, as the contract requires.

What about drawings from other CAD tools?

Any tool that exports a table of layer, length, area and count to Excel or CSV can be imported the same way.

Is the drawing revision kept?

Yes. Each imported row carries the drawing number and revision, which the client's engineer sees in the bill room.
