So how do you move them en masse? Do you create a group and drag it back and forth? I love your drawing and would love to learn how to draw that well. Mine look so childish.
Wo3Dan - they are exposed 3 x 6 rafter tails and have to look balanced from the ground looking up. They are spaced at 24" to keep that old school look. They are covered with 1 x 8 ship lap so an odd dimension at the ends won’t matter.
The roof rafters inside the building line are 2 x 6 at 16" o/c so the plywood aligns properly.
I wouldn’t bother with a group. Just select the rafters that need to be moved and move them. Hold Ctrl or Shift while clicking to add rafters to the selection or drag a selection box around the rafters you want to move.
Actually, I drew the first rafter centered on the end of the top plate and then copied it to make the rest on 24 in. centers. After they were done, I moved each of the end ones in 3/4 in.
I’m not sure what’s different. Maybe the style you have selected?
when I have tried that in the past it drags the wall plate along with it creating a weird shape which I have to delete and redraw. I have yet to figure out how to select an object that is attached to another without selecting the second object.
Perhaps I am not selection properly?
That sounds more like you are not using components correctly. You should model each separate object in the real world as a separate component (or as an instance if they are all the same and need to stay the same even if you edit). So, your rafters should be instances of one component, and the wall plate should be another component.
Components (and groups) are what isolates edges and faces from ones not in the same component. When you don’t use them, everything sticks to everything else.
Edit: as usual, @DaveR replied while I was typing!
Oh. I hardly ever do that. Maybe I should watch more videos abd learn better how. So, how many components are enough? A lot of times I scan a section of plans trace the walls and pull them up. Would I be better off making each wall a component? Or all of the walls one component, windows another etc.
I know it depends on the individual plan, but typically, what do most people do?
Recently I tried making a rafter a component. Then I took the wall line, selected it, divided it, Then copied and dragged the rafters over to the wall and tried to place them at the division points. It took a long time and looked pathetic.
I learn something each time I post here, but I feel like the person who stands at the base of a hill seeing it reach above the clouds, with no idea how high it extends. As I learn more, climbing up the metaphoric hill, I see the hill hasn’t gotten any smaller, but perhaps is actually a mountain.
As many as you need for the project? I would make a component for each discreet board. Of course you can copy components so you only need to draw one rafter tail, make it a component and then copy it.
There’s a better way. Place the first rafter as I said centered over the end of the top plate. Select the rafter and use Move/Copy (hit Ctrl after getting the Move tool) and move the first copy over 24 inches. Type 24 and hit Enter to get the move distance. Then, without doing anything else, type xn and hit Enter. n equals the number of copies you’ll need. Finally, move the end rafters as needed to place them correctly.
I was trying to draw a hip roof - the problem is that each rafter as you go up the hip is longer. How would you deal with that?
Do you drag them in place en masse and use some sort of intersect tool to trim them at the hip? If they are components, if you cut one wouldn’t you end up cutting them all? So you’d have to de-component them?
With a hip roof I like to stack the rafters over the studs. In the case of a “true hip” there is a common or regular rafter centered with the ridge. Therefore the studs and rafters are laid out from the center of the building. In the case below the three blue common rafters would dictate the stud layout below.
In the case of a hip roof, I would do as Shep shows working out from the center in each direction and I would make counterpart pairs unique ( i.e. 1st out from the center, 2nd out from the center, etc.) Then they can be trimmed to hit the hip rafters. There’s actually a handy simple trick for that which I can show you if you want. It would make the trimming much easier. Have to do it later, though. Maybe you want to connect like we’ve done before.
Shep - Oh, I know how to build a hip roof - I have built a bunch of them. Drawing them in sketchup is where my interest lies. On a gable roof, as shown earlier in the thread by making an array seems easy enough. However, on a hip, I was wondering if you would drag the array in place and somehow cut them off at the hip.
What never ceases to amaze me, is when you get down to building a hip roof, is how it always seems the cuts always need tweaking. They never seem to work out according to Hoyle. But, that’s another story for another day.
Dave, yes another day - right now I am swimming in estimates to get out, and am trying to wrap a job where the contractor can’t make up his mind and keeps changing things after they are built. It has dragged the job out terribly.
I hear ya, I’ve been lucky in that I learned to layout rafters with a framing square then moved on to using math and tape. Then came the construction master. But best of all Sketchup.
I think most problems in the field come from lumber that isn’t dimensionally accurate or straight.
You can return anytime for some pointers on hip rafters. You can probably search the forums here and find a few examples.
Think in terms of each stick of wood being a separate group or component.
Good luck with the estimating,
