Why Kotelys for this package.
The height makes the area
Give the partition type its height: every metre drawn becomes m² of partition, doors deducted at their width and height.
Flat by flat
One zone per flat or per floor, and the reports break everything down by themselves.
One type per system
72/48, 98/48, moisture-resistant, fire-rated: each has its colour, its total and its line in Excel.
Frequently asked questions
Another question? Write to us.
Is Kotelys suited to a drylining or plastering contractor?
Yes, it is one of its main uses: partitions, wall linings, suspended ceilings, angles and access panels are measured on the floor plan, flat by flat, with the voids-not-deducted rule of your contract.
Does a partition count both faces?
Kotelys gives the partition area (length × height), the usual unit in drylining bills. For taping or painting, count two faces in your estimate.
Can I get the perimeter of a suspended ceiling?
Yes: every area gives its perimeter in the take-off calculations and in Excel, for the perimeter angles.
Does Kotelys open DWG files?
No: Kotelys works on PDFs and images, scanned drawings included. Print a DWG to PDF at scale from your viewer.
How do I get the quantities into my estimate?
The Excel export gives a summary and the object-by-object detail, as fixed values. The PDF take-off calculations write out every calculation, to attach to your pricing.
