mike-h Posted November 22, 2007 Share Posted November 22, 2007 a quick one (I hope) I am making a basic building shell, and have 200mm unstyled walls. I have made 2 roofs, one with 2 gables, and a monopitch for a single storey extn at the rear. When I select a gable wall and hit "fit walls to roof", the wall disappears, or rather its delta Z height drops to zero. I have the 'create gable walls' box in the roof obj info box unchecked, as I want the walls to go up. The walls and roof are on the same layer. Can anyone tell me what I'm doing wrong? It is the same with both the roofs.. Quote Link to comment
islandmon Posted November 22, 2007 Share Posted November 22, 2007 Can anyone tell me what I'm doing wrong? It is the same with both the roofs.. Your roof was created atelevation Z=00 and needs to be set via delta or moved up to the correct height above the Wall creation plane which in this case is also Z=00 Quote Link to comment
mike-h Posted November 22, 2007 Author Share Posted November 22, 2007 I'm not sure I get what you mean... the roof bearing height is set to match the height of the walls that carry it - in this case 5800 for the main roof and 2700 for my monopitch extension. Everything looks at the right height in right/ left/ back view, but "fit walls to roof" reduces the wall height to zero. If your saying the roof still 'thinks' its at Z=00 - (which would make sense) then why would it appear (visually) at the right height, and show 5800 in the bearing height section. I can't find a specific z value field for the roof as there is for the walls.. Quote Link to comment
bonus Posted November 23, 2007 Share Posted November 23, 2007 Have you selected the right layer when hitting "fit wall to roof"? by checking "constrain wall to 3D" you get a choice of layers. If it's not the layer where the roof is, walls switch to ∆z=0. Quote Link to comment
Pat Stanford Posted November 23, 2007 Share Posted November 23, 2007 The roof needs to be on a separate layer for this to work. The command should actually be named Fit Walls to 3D Objects. Since the roof and the walls are on the same layer, the walls are being fit to themselves. Pat Quote Link to comment
CipesDesign Posted November 23, 2007 Share Posted November 23, 2007 More... the command fit walls "to top" of object will fit the walls to the lowest object(s) in the chosen "fit to" layer. Therefore Pat is correct. The best way I have found to make this entirely predictable is to create a 'dummy' layer, only used for fitting walls. You can place any 3d object into the layer, including roofs, floors or even simple extrudes... Quote Link to comment
mike m oz Posted November 23, 2007 Share Posted November 23, 2007 Peter's method is definitely the way to go. That way there is no ambiguity about the geometry you are 'fiting to'. The only think you need to watch is its Z height. (Oh how I wish there was a way tp switch the automatic incrementing of Layer Z's off). Quote Link to comment
