  1. Hi All Designing a new garage for the the house I'm buying (tear down 1-car and build 2.5 car). Going pretty well, but stuck on framing: Wall construction Treated bottom plate bolted to foundation maximum 6' apart, must be within 12" inches of all comers. Bolt size 1/2" x 10" Double top plate required 2x4 maximum 24" o.c. rafters to line up with stud below. Install 1/2" plywood or notched 1x4 wind bracing at comers in 2 directions from top diagonally outward a distance of 72 inches measured from each comer at sill plate. Short walls to be braced per current adopted !RC. Garage door headers, double 2x12 with 1/2" plywood flitch plate opening to 8ft. Headers up to 16 ft require a minimum 1/8" x 11" steel flitch plate with double 2x12 or equivalent. Large headers are to be sized for loads imposed. Roof construction Rafter minimum 2x6 up to 24' span. Ridge board 1 size larger than rafter. Minimum 2x6 ceiling ties maximum 48" on center 1/2" plywood or OSB roof sheathing rated for span Aren't Wall Construction No 4 and Roof Construction No 3 conflicting? I've never heard of a ceiling tie. I assume it's a rafter tie. If it's not a conflict, does it mean every other rafter tie has to be 2x6 vs 2x4? A few other points: I'm using 2 x single garage doors (probably 8 feet), so I assume I can just get away with 2x12 with 1/2 ply flitch plate. regardless whether I need the steel or the ply flitch plate, I'm gonna have to use 2x6 studs to support these aren't I? If I use auto framing can i just edit the suds under the headers to be 2x6 and will it retain this if I rebuild the framing? Can I build my own header material with the flitch plate? thanks Mark
  2. Thanks for tip. Would like to know who to do that. Have a few other questions too Below is the specs from the village: 5" concrete slab on 4" gravel/stone base Monolithic pour with 10"x20" perimeter grade beam all four sides Rebar: 2 continuous #4's top and bottom or 1 #5 in middle third of grade beam Siding 6" above grade, brick to be 4" above grade. 6 x 6 W 2.1xW2.1 wire mesh required Minimum 6 bag mix with 5-6% air. Is the surface of the slab normally level with grade? If so, I guess the stem wall would be required to better stop water, etc. coming in. Or does the slab sit partially/wholly above grade? How do i specify a stem wall. I have to use a monolithic slab (is a monolithic pour the same as a monolithic slab?), so the stem wall is disabled For the perimeter grade beam (No 2) do I just specify that as the slab's footing. I assume 10" is width and 20" is depth Thanks Mark
  3. Thanks guys I figured it would be the joist direction, but always get one of these errors "An end of this joist direction line is not within a ceiling or floor platform." "An end of this joist direction line is over an open ceiling or floor which has no joists." My current view is the plan of the first floor. I've tried drawing the line inside the room (not extending as far as walls), to inner edge of top plate, to out edge of top plate, to outer edge of roof, beyond edges of roof. No matter what, I always get one of those messages. I read the online help and check the training videos, but couldn't find a solution. Can anyone explain what's causing these messages It has drawn the joists in the correct direction (haven't got to setting height yet), but there are few issues (see attached) The rafter appears to be notched into the truss (see red arrow). How do I specify that these should lap each other The rafters are cut off at 90-degrees Yellow arrow). Normally, I would cut at same angle as the truss. Is there a way to specify this? Thanks mark
  4. Hi Guys I'm designing a two car garage and I want to have rater ties at the top of the lower third of the roof (so walls would be 9ft high, ceiling would slope in at sides and then level off where rafters meet trusses). This is the first time I've used build framing (used for kitchen and bath design previously) When I select build framing the roof is created, but the rafters (or probably ceiling joist) are perpendicular to the trusses and not parallel. So two questions really. How do i create rafter ties? How do I move them up from top plate? Attached is screen shout of what I have so far TIA Mark
