The zoning tool is designed to delimit a room into zones for the subsequent calculation of these zones as separate rooms. Zoning is implemented on the sheets Partitions (for dividing into rooms), Floor coverings (zoning floors for choosing dissimilar finishes), Ceilings (zoning ceilings for different finishes and assigning different values of ceiling drop), and Wall Finishing (through combined finishes). Zoning on each of these sheets works independently of the others. The zoning line (except for wall finishing zoning) can be built in any configuration (in projects version 3.0, in 2.2 - only a straight line from wall to wall), the main thing is that the beginning and end are closed on the walls and the zoning lines do not intersect with each other. In order to make zoning, select the appropriate tool in the menu on the left, move the cursor to the wall - a green circle will appear. Clamp and drag the zoning line - the segment can either be stretched in one straight line to another wall, or you can build a complex line from several conjugate segments. The zoning line should not cross other walls, partitions, columns or boxes.
