ChristianA Posted June 16 Share Posted June 16 Hi All, Please see the attached picture. This will most likely be a truss roof for the main roofs and sticks at the porch, with curved flairs framed on top. In my previous CAD package, I would just model this area and it would be be fairly easy to do. I don't even know where to begin in CA for the roof planes, let alone the framing. Can accurate framing even be produced for this roof? Curved roofs, overframed flairs, etc are probably my weakest area in CA. Thanks in advanced for any guidance.

StephenGreene Posted June 16 Share Posted June 16 absolutely possible; i've done several. the Chief Training Videos are where i would start. https://www.chiefarchitect.com/videos/watch/1956/flared-roof.html?playlist=95 Link to comment Share on other sites More sharing options...
ChristianA Posted June 16 Author Share Posted June 16 Thanks for the link. I've watched this video before. It solves the geometry,but I think it will create a truss with the top chord flaired. That does not happen in real life. Not a deal breaker, as I can draw a detail of that area. But it would be nice if CA framed it the way it will be built.

GeneDavis Posted June 16 Share Posted June 16 Here is another video. Your framing details are going to be done by you using Chief tools. Chief does not autoframe this, but it will model it in 3D for you with you using the available roof tools. As for con docs, the little bit of shipbuilding needed for these two small segments and their valley is going to be done by you using CAD. What software produced the 3D model you show in your opening post? Does that software autoframe this? Link to comment Share on other sites More sharing options...
ChristianA Posted June 16 Author Share Posted June 16 This was provided by my client in sketchup. My previous software was Autocad with an AEC BIM-like add-on. Not nearly as advanced as Chief, but modelling was easier to produce things like this. It's not that big of deal to have to detail it separately.

ChristianA Posted June 16 Author Share Posted June 16 A quick screenshot of a perspective view from an old project. A layer of curved framing on top of a clipped truss. Link to comment Share on other sites More sharing options...
para-CAD Posted June 16 Share Posted June 16 You’re not doing your Framer any favors. Link to comment Share on other sites More sharing options...
ChristianA Posted June 16 Author Share Posted June 16 (edited) I don't necessarily disagree with you. I don't design these homes, I just engineer them and draw them. These large radius roofs are a pain and expensive, but the builder/homeowner wants them. We are in area with high snow loads as well. Most of the spaces below these roofs are open, so you are either holding it up with massive steel ridges or clear span roof trusses.

para-CAD Posted June 16 Share Posted June 16 (edited) We laminated 3 quarter inch plywood to make curved rafters. This model is close.....it was hard to slope out to the edge in the model. On-site, we adjusted the template until we got what we needed. This was in Memphis, TN. Curved framing is my kryptonite Edited June 16 by para-CAD Link to comment Share on other sites More sharing options...
ChristianA Posted June 16 Author Share Posted June 16 Clean framing! I've definitely done things similar to this. It's a case by case basis for me. The above example i gave would have had 36 foot mid span and / or ridge beams. Link to comment Share on other sites More sharing options...
