Trouble with intersecting roof lines
-
Hello, I am very new to SketchUp and this site.
Here is my problem. I am Sketching a home from a picture but there are a bunch of weird roof intersects. I'm not quite sure how to get these done. I have attached a photo of the home I am trying to model. Can you give me some pointers. Thanks

Good job Voder.
caliliving here is some roof tutorials:
That second one helped me a lot

Thanks for the help.. I finally Got mine to look like yours Voder. Can I ask how long that took you?
Took me over three hours.. (first model ):shock: I think I had the wrong approach I was trying to do everything at once...But thanks for the help

caliliving,
It looks like Voder used intersecting planes. (How about it, Voder - is that right?)
Once you've mastered SketchUp's inferences, rotations and intersecting, you can probably do this in less than 15-20 minutes. Often, the one of the toughest tools to master is rotation. Once you learn how to use rotation's power, a model like Voder's will be simple for you, too.
This rotation trick took me a while to find:

Hello again... Thanks to everyone for the help..
I have one more question.. I can finally bust out a soild model like the one attched in 10 min...
But the problem I have now... Is when I offset the roof 1' out to make the overhand it doesn't line up with the intersecting roof line(even tho they share the same side wall).
If anyone can tell me what I am doing wrong it would be much appreciated.
and I have watch almost all vids on making roofs, I thought I had it......I have attached two files. One with just the house envelop and the other showing what the problem is.
Thanks

Hi again, Caliliving.
I'm not an architect and I'm afraid that I'm just a dabbler in roof modeling, so I don't know about the classic traps, but I can offer a few suggestions.
However, before I do, I'd make the observation that when I first looked at the house envelope model, I immediately noticed a lot of odd-looking line segments around some of the intersections. So I orbited around to look at it from below and deleted the floor so I could look inside. Yikes, man, what a mess. It was all full of stray edges and faces, apparently left over from a tumultuous modeling process. I sympathize with the difficulty you ran into, but I would suggest that you try to clean up all that stuff as you go so it doesn't accumulate.
As far as the overhang, instead of offsetting the edge all around each roof plane, just go with two adjacent edges at a time, and when you come to a hip or valley, use parallel inferencing to extend the intersection line out so you can miter the overhang neatly on the same intersection. The reason you ran into trouble at the intersection of the front gable overhang with the main roof overhang is that the former is extending at a downward angle while the latter is extending straight out horizontally. The overhang on the front gable may be a foot in extent, but it only extends horizontally by 10-3/4". Bring the gable overhang around until it hits the projection of the valley at that point, and then just follow the edge of the main roof with parallel inferencing.
I've attached another .skp for you to look at.

I can see that you have fallen into a classic trap, and it is messy trying to develop the roof from where you are now.
Before you start (!), I have found it best to create the overhangs, on plan, before you start, so that the roof extends out to the overhangs from the outset. However, if you want to move on from where you are now, I would create the depth of the fascias on each gable end and pushpull it out 1'. You will still have to do some tidying up at the junctions.
Another thing is, whilst I think roofs are tricky and thus a good learning exercise, if you draw roofs often, then do yourself a favour and get 'roof.rb' - its free and it makes roofs in an instant!!Its here http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=3470&p=74746#p17156
Good Luck

Hi Caliliving, hi folks.
I prefer to use the following sequence:
1 - Draw the outside outline of the roof.
2 - Build the roof.
3 - Close the bottom face if it is not already closed.
4 - Pull down somewhat to make the sides of the soffits.
5 - Do an inside offset corresponding to the wanted horizontal overhang.
6 - Pull the house itself down.
See attached SU file for ideas.

Cali,
Yep, following some of the examples given and some videos will help. I've tried like you and there's quite a few tricks they've already figured out for us...
On the overhang of the gable vs. the eave. It's not so much your modeling approach (although it does look like it'll cause you extra work) it is just that if you want an even fascia line there you simply have to figure what that plane is from the wall line. I have used the measuring tool from a vertical corner and established the 12" overhang measured at a horizontal (the way it is usually given in plans),instead of measuring at the roof angle. So you see, 12" measured (or offset) on a pitched surface will be different than 12" offset horizontally. Besides I'd usually let the gable barge rafter come out further to receive the gutter on the eave.
Is that Woodland California? Or just another McSubdivision like the one I used to live in?
Good luck

I'd also suggest you look Aiden's YouTube video on Intersecting, that uses multiple rooflines as and example.

Thanks Galen, you saved me making a model to explain: Lately I have been push-pulling elevations instead of plans to start a model...and the speed in which they come together amazes me. I'd suggest heading this way.
-
OK Tom. I'd like to see a push-pull elevation demo!
