I have an A/C object that I would like to have a flexible slab. when we change the size of the unit (say from 12kW to 20kW) I would like the slab to change to suit the default size and then be stretchable after that. my problem comes when you reset to a smaller size unit and it maintains the larger slab.
My thoughts are to somehow get it to update to a default value when the kW parameter is changed and then allow a range of inputs. on the next kW change it would reset to the appropriate value for that size and then allow the stretch again.
I don't know if i am maybe attacking this in the wrong way but I have googled my heart out and am at a wits end
