machuofm Posted September 29, 2005 Share Posted September 29, 2005 Does anybody have any suggestions as to what is the best way to create complex roofs. The roof I am trying to model is too complex for the computer to create. Is there a way to do it in sections and join them together? The roof doesn't have any organic forms to it. It is composed of standard slopes and valleys but with multiple sections to the house and different eave heights. Any help would be appreciated. Quote Link to comment
CipesDesign Posted September 29, 2005 Share Posted September 29, 2005 There are a couple ways to get there. 1) Draw the roof in plan view. Make sure that each face of the roof is a closed polygon. Select eact polygon (one at a time) and use the ROOF FACE command (in the AEC menu). With a poly selected the roof face dialog allows you to enter all the relevant info and then when you click OK you need to draw a line perpendicular to the slope of the roof, then click, then make sude the little arrow is point UP the slope and click again. You can adjust the height(s) of a face(s) by changing to a front (or side) view and using the MOVE command. 2) Draw two (or more) simpler geometric shapes and use the CREATE ROOF command on each one. Afterward you can UNGROUP each ROOF and you will end up with a bunch of ROOF FACES. You can edit a roof face by double clicking on it, which will reveal the 2d shape in plan view. You can work on the 2d shape by adding or clipping surface, or simply using the 2d rehape tool. Hope that helps! Quote Link to comment
islandmon Posted September 30, 2005 Share Posted September 30, 2005 Or just use standard trig. based on slope angle and the sqr2 ( for 90? corners) to create 3d Loci in XYZ space then connect the dots with 3D polys. Quote Link to comment
islandmon Posted October 1, 2005 Share Posted October 1, 2005 Also keep in mind that you never need to make the entire roof.Usually only 1/4 of the structure is required then save as symbol and dup&reflect. to make complete structure. Quote Link to comment
CipesDesign Posted October 1, 2005 Share Posted October 1, 2005 EJ, really? Even for asymetrical buildings? I'm not sure I follow... Quote Link to comment
islandmon Posted October 2, 2005 Share Posted October 2, 2005 All shapes regardless of 'apparent' complexity can be reduced to a few interrelated associations. This is especially true of roof surfaces which ultimately must be constructed by the hand of man in the real world. Changing heights/pitches just mean that there are different surfaces which must end at different riser walls of some sort or other. Geodesics which change dihedral slopes are just the re-combination of a single multi-frequency divided triangle. Quote Link to comment
Jonathan Pickup Posted October 2, 2005 Share Posted October 2, 2005 my Architect Tutorial manual has several pages on how to model complex roofs. There are a few ways to make complex roofs and it depends on what information you have to start with... https://plus36.safe-order.net/archoncad/manuals/manuals.php Quote Link to comment
