Hello, Mine air is compressible, otherwise it would be considered an ideal gas and the laws of physics could not be applied to the power of the fan motor and other factors that regulate a calibration inside the mine. No matter how small the mine is, it must be considered compressible to avoid errors.

Thank you, with the measurement tool if it can be done.

Dear Martin, the version I use is 5.4.8.2 and it still has the same problem.

Previously in VentSim you could draw in plan and then you would place the gradient and move all the ducts with the gradient, however now it does it differently by ducts. Any solution,thanks for the reply
