Yeah, i cannot save right now, I am tempted to buy this but; because it is a rather expensive outlay, I need to make sure it works fine with our building codes. To buy just for the save function is not be ideal.
I had someone create the plan with same settings so i could upload it.
That 37mm plate you talk of, that is the same measurement i am seeing as an indent on the top of the wall. Is there any where one would set up the materials and sizes of that plate ? We use a similiar method, but it is a 38mm x 114mm timber beam, placed on top of the wall. i would need to adjust the plat to that size, yes ?
Our ceiling battens are 38mm x 38mm, spaced 300mm apart on the centre-line. We use 6mm Ceiling board here too, and because of the close battens no wavy-ness to speak of.
I am going to read up about ceiling structures, and see what I come up with - I have not being playing with it for long and am not yet familiar with ceiling structures other than the ceiling section on the Structure section of the Room Specification Dialog.
