    How to display the layers in an assembly

    Hi there Chopsaw, I’m in Berkeley CA. so last snow was in about 1979. About all 1” of it. The roof will be unvented with 5 1/2” of closed cell foam. Not sure we really need to worry about thermal bridging, but I want to minimize rafters on that layer. Still I think your idea of blocking every 4’ would suffice. Glen, I am assuming you don’t have any surface layers in your roofs, and how do you get those pretty display colors? Anyways, if you do specify a roof surface layer on that top roof, how do you turn it off without turning the roof plane off??? FYI, I will be headed in to the Ventana wilderness starting tomorrow and won’t be back until Oct. 30th. So if you perceive radio silence, that is why. I’m grateful for your replied and suggestions. Thanks, Bernard

    How to display the layers in an assembly

    Hi there Chopsaw, I'm using 1 1/8" ply on top of the 4' spaced rafters. I could throw in a header/blocking at the mid point so every other joist goes wall to wall and every other one gets the blocking/header. But i think that 1 1/8" will suffice. Plus the sleepers get A35 angles every 2'. I used this span table and I'm hoping the inspector buys it. But I'll let the inspector make the call. Glen I noticed your upper and lower roof framing is spaced the same, whereas mine would be spaced 4' oc on the lower roof and 2' oc on the top roof. With your fast mock up, was this possible? I will check out the poly base line tool Glen, to see If can make it work. Thanks for both of your replies.

    How to display the layers in an assembly

    Hi Chopsaw I am trying to get everything close enough so that I minimize the cad work when I get going with the real plans. So far I've had to build the blocking because i chose to use exposed rafters and then originally I was going to use sip panels above that. After pricing and availability, decided that I'd go with the same exposed rafter layer with plywood on top , then 2x6 sleepers with spray in closed cell foam on top of that, then finish off with the roof surface layers of sheathing, membrane and standing seam. So essentially I built a second roof on top for the sleepers but realized they would have to be built manually. the 4x10 on 4 ft centers default won't let me build the top part of 2x6 at 2 ft on center. Ie, If I retain or lock the bottom roof, I am unable to edit the second roof. I'm thinking there must be a way to edit multiple roof style in the same plan? I thought this may have been stopping me from peeling the surface layer off to see the 2x6 layer framing. But there is no 2x6 framing being generated and the materials definition won't let me choose 2x6 rafters on 2' centers. Only studs you can see in the pics the space where the sleepers should / could be (circled in red). The reason I built it this way is because the rafters would be built this way in the real world. Ie on top of the wall. If I had gone the other route, I would have had to manually draw the 4x10 rafters and the wall framing would have had to be drawn also. so a lot more work. It's becoming more evident that I will just have to finish the CAD details manually for the 2x6 sleepers. Piece of cake. But when I read this thread, I thought hmmm, maybe peeling back the layer was a possibility. Sorry for the long winded reply. Bernard

    How to display the layers in an assembly

    Hi There Is there a way to do this with the roof layers? I was trying to toggle the roof surface layer on and off so that i could just see the framing, to no avail so far. Thanks, Bernard

    Sip Roof Panels on Top of Exposed Rafters

    Hi Chopsaw and Brown Tiger Well I tried the Rafter for the pitched frieze board and that work pretty good. Then I tried the same tool for the blocking but it just carried through on the rafters, which looks okay but technically is incorrect. So I tried the blocking tool and as long as it had a rafter to snap t, it worked great. It's a lot easier to align the edge for the sheet rock in one pull as opposed to using the rafter tool which then had to align on at the edge of the plate for each and every rafter. So I'd say this is a good work around CA's inability to generate these boards. Of course, then I decided to change the pitch for fun which messed it all up and had to start all over again.(lucky it was a copy). Thanks you everyone for the input. Bernard

    Sip Roof Panels on Top of Exposed Rafters

    Hi Chopsaw Thanks for the reply. So are you suggesting using rafters for the frieze boards and also for the drywall nailers between the 4x10 rafters? And for that matter the frieze board going up the gable end walls. I’ll give it a go in the morning and let you know. The blocking between the rafters are pretty straight forward. It’s just the pitched frieze board that wants to go off pitch willy nilly. Maybe I’ll try copying the rake board over for that and do the blocking on the too plates to see how that works too. It would still be nice to have those auto generated, seeing as this has become a prevalent form of construction for quite some time now. Thanks again for the work around tip. Bernard
  7. Hello folks I just upgraded to Chief X12. Steep curve for me, still trying to wrap my head around the plan view/layer set, but I'm struggling. I have been trying to generate a roof structure with exposed 4x10 rafters @ 4' oc, exposed plank soffit on the over hangs and 5/8" drywall on the interior vaulted ceiling. On top of that layer will be 1 1/8" ply to which the drywall will screw up into. So far I've composed this on the structural layer. On top of that (built on the ceiling surface layer) is the 5.5' closed cell foam/EPS capped by the sheathing, membrane and standing seam roof. I tried manually drawing the rafters and using a regular 2x6 framing to house the closed cell foam but the framing would not generate around the rafters and it would have taken a lot of work. So decided on the rafters on the structural layer leaving me with(or so I thought) the lesser task of inserting manually drawn frieze boards/ blocking at the top of the walls. (Since it is not apparent that Chief is able to generate those automatically, only at the outer perimeter overhangs). In Chief, the space between the rafters is usually filled with insulation and sheet rock applied underneath to form a vaulted ceiling. Those frieze boards and drywall nail blocking would be generated automatically and that would suffice, but today's modern SIP panel construction for both roofs and walls, are composed such that they need both frieze boards and blocking to be generated at the top of the wall, which it appears thus far, Chief Architect cannot do. Hence the attempt to manually draw the frieze boards and blocking, as the roof structure and surface layer will only generate on the perimeter eaves and rakes. Please see the attached drawing for a breakdown of the layers. If there is a way to simplify or achieve this through Chief Architect, I would appreciate it if you could let me know. I've attached a video demonstrating what happens to the frieze board manipulation which takes foreveeeer (and sometimes never) to get in place and maintain the correct roof pitch. Please inform me if this is a bug or not. If there an easier or different way to do this, or if there is a work around to create this type of roof. I am trying to maximize automation and minimize unnecessary cad drawing. Okay thanks for your time and appreciate any input you might have. Bernard Video_2020-09-10_115941.wmv
