JKEdmo Posted March 14 Share Posted March 14 I'm trying my hand at auto rebuild roofs and have a problem with an offset valley: Here's a sketch below with the plan and roof planes shown: I have a smaller gable intersecting a larger gable. The valleys formed left / right of the ridge are not meeting together because of a slight stagger / offset. I think I know what's going on, but don't know how to correct it... On the left side, the valley is forming correctly directly over the intersection of the face of studs (shown by orange construction lines). On the right side, the valley is instead forming over the wall break point, which is where I change from a hip to a gable wall and also happens to be at the centerline of interior wall meeting the exterior walls. This appears to be causing the misaligned valley. I'd like to shift the wall break down to mirror left side condition. However, this wall break keeps snapping back to interior wall centerline. Ideas? I hope this is clear enough, but I can upload the plan if needed. Thanks again! Jim Link to comment Share on other sites More sharing options...
Kiwideziner Posted March 14 Share Posted March 14 Jim why is that roof plane that has the arrow drawn on it not 1 plane right across.?? Link to comment Share on other sites More sharing options...

It should go across, but that's the result auto-roofs is giving me. This is the thing I'm trying to correct. Jim Link to comment Share on other sites More sharing options...
Kiwideziner Posted March 14 Share Posted March 14 Jim Now I understand, it is really hard to get auto roofs fully correct. I would just manually fix up that 1 plane and be done. Link to comment Share on other sites More sharing options...

Mark3D Posted March 14 Share Posted March 14 See if that is correct i just added a gable line so auto roof are good others may have a better way BASSETT 2 - PROPOSED.zip Link to comment Share on other sites More sharing options...
JKEdmo Posted March 14 Author Share Posted March 14 10 hours ago, Mark3D said: gable line Mark, I'd like the valley to occur farther down the plan so there is one ridge on the main gable running left/right, but thanks for pointing me in the direction of this roof tool I wasn't aware of. I think it's exactly meant for the problem I have. I'll play around with it and see if it works. Thanks again, Jim Link to comment Share on other sites More sharing options...
Mark3D Posted March 14 Share Posted March 14 (edited) See if that is any better i got rid of gable line as it was stopping roof on soak tub room and used Make roof base polyline and tweek it at the problem wall intersection, so now auto roofs will only build to roof base polylines so if you change your model you will need to change roof base polylines BASSETT 2 - PROPOSED.zip Edited March 14 by Mark3D more info Link to comment Share on other sites More sharing options...

Much appreciated. I'll take a look at your tips tomorrow. I wound up proceeding with manual roofs, but I would like to get better at auto roofs.
