    best way to add exterior corner board trim, and roofline trim boards?

    This is for 1x6 trim. I have a wall family that has: clapboards-sheathing-stud-gwb. So ideally the clapboard portion of the wall would stop 5.5" from the ends where it runs into the vertical trim boards.

    For such a standard architectural feature I'm surprised Revit doesn't have it worked in, how do others deal with exterior trim?

    I don't typically work on projects with siding and trim, but there's a few things you can try. Wall sweeps that cut wall could be one. Wall-hosted families that cut the wall is another. The cut would equal the depth of the siding.

    Id use a line-based generic model with the wall face as the work plane and join it to the wall to cut the siding layer/wall.

    thanks for the tip, after fighting with sweeps I may try this, as someone new to revit... how do I do this?

    Youll need to get some training to get more out of this;

    Start with a line-based family template. Switch it to Generic Model if its not already (it likely is). Model the trim board as a sweep with a profile or an extrusion adding parameters as/if required to change width, thickness, and any offset from the placement work plane. Constrain the ends of the sweep or extrusion to the reference lanes on both sides of the built in reference line. Assign subcategory and material as needed.

    Its simple to do but complex to understand (at first itll become second nature before too long).

    We have a face-hosted family for flat trim, specifically for things like this. We have one family with Type parameters for the board size i.e. 1x6, and an instance parameter for length. Then we also have another family with instance parameters for both length and width, with only the thickness as the type parameter (useful for odd-sized rip-to-fit trim boards).

    You could also set up a wall-hosted or face-hosted family with both corner trim boards, to use for the corner conditions.
