ACADuser Posted April 24, 2015 Share Posted April 24, 2015 Wanting to create this design, see attached. I am restricted to 8/12 pitch on the main roof, Do I need to rebuild the existing roof plans or can they be converted. I hate that ALL roof planes are removed as two are not o be this type & have differing pitches & materials on them. I see that manual roof planes can be preserved. Good. That means I have to rebuild them separately every time i rebuild the roof. Link to comment Share on other sites More sharing options...
rlackore Posted April 24, 2015 Share Posted April 24, 2015 There is a step-by-step section in the Reference Manual on how to accomplish this condition. That's how I learned: Link to comment Share on other sites More sharing options...

ACADuser Posted April 24, 2015 Author Share Posted April 24, 2015 Yes reading the manual I was able to create a curved roof plans but as usual I am falling short of my goal. There is missing information as usual or I'm just not smart enough to figure it out. I do NOT want a completely curved roof plane. The first 24 to 36 inches are to be curved and the remaining roof plane to the peak is to be 8/12 pitch. My attempt below is to use two roof planes but joining them is a problem for me. Maybe I missed a step in your example & if it can be done with one roof plane, if so please point me in the direction I need to go. Thanks for your help.

rlackore Posted April 24, 2015 Share Posted April 24, 2015 I can't open your file - I'm on X6 until my computer is upgraded (ran out of disk space). Be sure to draw the lower (curved) roof planes first, curve them, then draw the higher roof planes with the baseline along the ridge of the lower (curved) plane.

ACADuser Posted April 24, 2015 Author Share Posted April 24, 2015 Thanks, Found a Video that outlines the process necessary for this. Walls need to be modified before creating the roof. Link to comment Share on other sites More sharing options...
rlackore Posted April 24, 2015 Share Posted April 24, 2015 Really? I don't think you have to do anything to the walls. Works for me with or without walls. Link to comment Share on other sites More sharing options...
DRAWZILLA Posted April 24, 2015 Share Posted April 24, 2015 You can do your roof planes in the roof plane DBX ,or the wall DBX for different pitch than default auto roofs. Link to comment Share on other sites More sharing options...
ACADuser Posted April 24, 2015 Author Share Posted April 24, 2015 The process that worked for me on my sample house. Select walls under roof to be curved.Under Roof / Pitch Options enter the LOWER pitch (3) Check Upper Pitch, then the Upper pitch (8)Enter "In From baseline" use a smaller number than you think. For pitch to end at say 36" in from fascia enter 15"Use CA "Build Roof" dialog and CA creates two planes, one at 3/12 and one at 8/12Select all the 3/12 roof planesGeneral / Curved Roof check it and enter "Angle at Eve" about 3 deg. & hit OKBingo!

ACADuser Posted April 24, 2015 Author Share Posted April 24, 2015 Really? I don't think you have to do anything to the walls. Works for me with or without walls. You need the walls to use the CA "Build Roof" dialog to build then for you. Link to comment Share on other sites More sharing options...
rlackore Posted April 24, 2015 Share Posted April 24, 2015 You need the walls to use the CA "Build Roof" dialog to build then for you. Got it. I've never figured out auto-build for complex roofs. Link to comment Share on other sites More sharing options...
ACADuser Posted April 24, 2015 Author Share Posted April 24, 2015 Build Roof is useful in this situation as I needed to tweak the baseline offset and eve pitch several time before I got it correct. I still need to select all the lower roof planes and re-enter the Curve data each time but easier on a 4 wall building than on the actual house.

VisualDandD Posted April 24, 2015 Share Posted April 24, 2015 Those type roof are often done with just simple 'kickouts' rather than full radius. In fact, I have never seen them done radius-ed at the end, except for an asian inspired design. Something to think about, but I use similar details often and it is just a lower pitch by scabbing 2x6 on the rafters at the end. Even from the pic you posted, I cant see that that are a true radius. I would put dollars to donuts that it is just kicked out tails especially given the style of the home. From a field standpoint.....it is MUCH MUCH easier to construct as well. Just a thought.

ACADuser Posted April 24, 2015 Author Share Posted April 24, 2015 Yes the truss guy will build them but I want a pretty picture for the clients. I too doubt that there will be radius. I guess the truss will look like this. Link to comment Share on other sites More sharing options...
TheKitchenAbode Posted April 24, 2015 Share Posted April 24, 2015 Not sure how they do it but that style with an actual radius is very popular in rural Quebec. May wish to google around for Quebec based truss suppliers. I'm certain you'll find one that shows this. Most have English site versions.

TheKitchenAbode Posted April 24, 2015 Share Posted April 24, 2015 Here's a link, shows the style you are looking for. There's a pic of this being framed, you can see that it has a radius, looks like the extension piece has a radius. There is another project in their gallery that shows it done as just a straight angle. http://www.greatnorthernwoodworks.com/curved-roof-craftsman/ Graham Link to comment Share on other sites More sharing options...
VisualDandD Posted April 25, 2015 Share Posted April 25, 2015 Quick and dirty example of how I do it. Like I say in the vid. I get all my roofs right first, and this is the last part I do. Link to comment Share on other sites More sharing options...

ACADuser Posted April 26, 2015 Author Share Posted April 26, 2015 Way to go Justin! I did not do it exactly as you but you furnished the key to the process. The roof is too complex to auto build as the CA documents suggest to do it. Your copy in place saved the day. I used a cantilevered overhang truss so I had to get the desired base line height from a cross section view. Then I used transform replicate to set the lower roof plane height. This gave the exact number I used for ALL the remaining lower roof planes. I did the same for the upper section to establish the location of the joint between planes. Once I had that baseline height I plugged it into the remaining upper roof planes. Then joint upper & lower planes. Obviously there was some planes that needed to be cleaned up at ridges & valleys but once figured out it wasn't too bad. Thanks again. Link to comment Share on other sites More sharing options...
yusuf-333 Posted April 27, 2015 Share Posted April 27, 2015 Here is my take on the issue, an other example for any one interested, I tried to create the curve with smooth transition at the point it meets the straight one. https://youtu.be/RTn1xDLQ1mg Link to comment Share on other sites More sharing options...
