Re: Guide To Creating A Flat Roof With Cut Outs For Skylights The next step is to add a level [menu option] Plan -> Add level This will do two things... 1. It will signal to Sweethome that we want the Skylight tool to cut a hole in the ceiling - Sweethome will not cut the hole if there is no upper level. 2. It will give us a place to construct the roof, actually as far as Sweethome is concerned the roof is really an upper level floor but for us its a roof. A note about levels ! When you create one you are asked for an elevation and a thickness but the elevation is measured to the top surface of the floor ( which for us is actually going to serve as a roof ) This means if your walls are 200 cm high and you want a roof that is 40 cm thick then you need to set the elevation to 240 cm, this will mean that the roof will sit on top of your 200cm walls. It may help to think of the roof not sitting on top of the level but actually hanging underneath it. I gave my level a sensible name Roof300 which indicates the height of the wall it will sit on - this is because I have different blocks in the building with different wall heights and so I need to have all roof sections at a particular height in the same level. To review, if the walls in question are 300cm high and the roof is set to 40cm thick, I need to create a level with elevation 340cm. Once the Roof (level) has been added the Skylight tool can actually cut a hole in the ceiling, however we will not see a hole ( viewing from underneath ) until the Skylight tool has been made invisible since it obscures the hole it makes. Here are the steps Select the Skylight tool. [ menu ] Furniture -> Modify ( or right click ) to modify the Skylight tool. Choose materials -> modify and set all 6 faces of the skylight tool to be invisible. This will not work using the visible 'box' in the home furniture list as that only indicates whether the Skylight tool should be present or absent in the model. Once this has been done then when viewed from underneath the ceiling should have a hole. If this does not happen check the following. 1. Is the Skylight tool invisible? 2. Was the level added? 3. Is the Skylight tool high enough to cut the ceiling. continued in next post |
