Gable & Eave Details
I'm adding additions onto and restorating an early 1900's house and the owner wants the exisiting roof details on the new additions (attachments). The rafters are a full 2x6, but the exposed tail is cut dow to 2x4 with a tail detail. The Gable is a detailed 5/4x8. There is no soffit. The underside of the roof sheeting (T&G beadboard) is exposed. The 3" drip molding that is used on the Gable fascia is what is used for the Eave fascia. I hope from this explanation and the attached pictures you will understand what I'm trying to accomplish. Can anyone give me guidance or steer me to some training video for guidance?

Hi Larry,
I usually just draw a polysolid in elevation and replicate. HTH.

Larry, Won't the rafter tail tool allow you to recreate that shape? Googel "rafter tails chief architect" there's a bunch of help there.
...or video 1030 if you have SSA.The purpose of Government is to control the common resources, not the common man.

How do you deal with the roof on the eave overhang since the bottom of the sheeting (beadboard) is exposed? I'm thinking to use p-solids for the rafter tails you would need to have the eave overhang a different roof plane with rafters 1/16"x1/16", which would then be hidden by the p-solid rafter tails. I'm playing with different options. I think I might have to use a different roof plane on the gable overhangs because the Gable fascia rafter is a different size than the other rafters. Also the tail detail on the gable fascia is different than the regular rafter tails. I wonder how the valley rafter is treated with the "tail detail"? I don't think you can have different tail details on the valley rafters as compared to the regular rafters in the same roof plane. I'm hoping I can use a shadow board for the drip moulding on the gable and eave even though I have no fascia board on the eave. I really couldn't find any info pretaining to this particular problem. It's going to be a lot of head scratching this afternoon I guess. I wonder if X6 gives us a little more leeway on these kinds of options on roof details and framing? I asked about being on the beta team, but never heard back from CA. I have not had any experience with beta before, which my be the reason, but you would think that being a customer since version 10 they would have at least gave me some sort of reply. I've always been current with SSA.

Larry.......I checked out video 1030 earlier and to your answer it is a partial "yes". It's all the other items I mentioned in thread #4 that I'm trying to put in order. I thought that before I started doing to much head scratching I'd check in on Chieftalk and see if anyone else had come across this kind of project and figured out what worked and what didn't. By the end of this afternoon I'm hoping I'll be able to post what worked and what didn't. That is if my ideas follow through and there is enough coffee in the pot.

Just build the roof framing and leave the soffit off. Once you have everything the way you want it, go back and edit the framing members size.

When making a custom rafter tail and sending it to the User library, what area should you store it under? I stored mine under My Moulding/Rafter tails. When I loaded it into my roof's rafter tail section it came up looking like in the attachment. You can see only one or two faces at a time. When I load one of CA's rafter tails everthing looks correct. The only thing I can think I'm doing wrong is that I'm sending my custom rafter tail drawing profile to the wrong area in the User library.

If I had to guess, it is not a molding, I think you should of saved the profile to the library and if defaults to the USER LIBRARY. It is simply a profile, not a molding, guess you can then put it into a library called USER RAFTER TAILS, I would check if I could, but since up recently tried to upgrade CA on my HOME MAC and failed, I can not confirm.

Larry,
Check this knowledge base file. The title is about Beams but it explains the custom rafter tail process exactly.

I made a new rafter tail profile, which I show in the attachment. I then added it to my user library under "My Exterior Attachments/Rafter Tails" and got the same results I show in thread #7. Has anyone else made a custom rafter tail profile and had the correct result? If so, did you go about it in a different way than what I've explained in my threads. I just started putting this as-built plan together, but I'll attach it. I left the rafter tail profile I made on level 2. I'm hoping someone can explain to me what I'm doing wrong.

When you create your rafter tail, be sure it is a closed polyline. I believe that will solve your issue.

Perhaps, but the link I referred to states that it should be open.
"Rafter tail profiles function like molding profiles, so they need to have an open shape with the opening on the left side of the polyline."The purpose of Government is to control the common resources, not the common man.

Robert....I'll have to agree with Larry from what I have read up to this point. Has anyone tried making a custom rafter tail and then applying it to the Eave of a roof? With what kind of result?

Robert.......You're correct! The reference manual is wrong or at least in this case. I'll have to try this in another simple plan with a different custom rafter tail profile and see if I come up with the same results. Thank you and to all who have taken time to help me out with this problem. Have a great day.
