    Has anyone here ever been the first to have the maximum trim in the space for their electrics? Today I went to set the trim on my fourth electric at 36' and realized the max in the space was 32'4". *lol*

    They had never had anyone set a trim that high.

    Well, I have never maxed out an LX but I have certainly been in positions where I wanted to push the roof up a few feet...(10' ceilings anyone)

    Try 9', our local community playhouse has 9' ceilings on the stage. No fly system just rafters, it used to be a barn on the county fairgrounds. So...9ft ceilings and an 8" fresnel hum...

    Reminds me of one of the black box spaces I used to work in at Orange Coast College, except it was a converted classroom and we had 6" Fresnels.

    I top out our third electric (only four inches from the pulleys) to kind of mask it and increase the beam spread for back lighting. Our other two electrics have another two feet to go before topping off. (24 foot ceiling, highest lights can go is about 23 feet)

    36' feet is only 10' higher than our proscenium, so i wouldn't put it past an LD to set a trim there. Since max trim is 63' I doubt we will ever have to hang anything there.

    I just retrimed the electrics and boarders this morning.
    Our Proscenium is 19' 6" and 2nd and 3rd electric is trimmed at that. First electric is at 19' 3"

    I just finished a community theater gig, where there was a really low roof. There is piping and stuff under the roof so there is no real way to hand lights there... So I only able to hang 3 backlight pars.

    Yup and I also have hung more lights on a batten than could be counter weighted. Silly double purchase system. The arbor was tell enough for the extra few bricks that I needed but there was no way to get them into the arbor. X-Spots are made of dark matter if anyone was wondering.

    I top out all the time when we need to bring the shell system in. Aside from that though, I tend not to do in my resident theatre, but that's because the distance to the grid from the proscenium is over 20'. The highest trim I've done in there is about 32' from the floor.

    Now in one of the theatres I overhire at, they top out everyday because they're in a renovated space and didn't even have LX. The condition the current TD made, among a few other things, was that he would not accept the position unless they installed LX. Unfortunately it's a tight space and their grid is always synonymous with trim height of the lighting.

    Can you attach a .pdf of your Vertical Section so we can see the issue in context?

    You guys are going to love this (keep in mind this is a professional resident theater group) the scenic designer quit a couple of weeks before build began and took all his drawings with him. So they tried to recreate the set (without violating the original artists intellectual property rights) so the new designer began working on it, and for some reason just seemed really distracted through the whole process, so that the set was redesigned at least a dozen times between the time he was brought on, and build.

    So when I got paperwork it was not in scale (but at least the ground plan had all the depth measurements marked) and there was no section. So I did my best guesstimating at the heights (4' platforms, 8' walls, etc) for hang. They installed the set the day after hang and I came back a couple of days later for focus and find out the wall heights had changed again.

    So the spaces 4th electric when from being useless (with 8' wall heights) to actually quite useful for back light with the new 4' high walls, but some quick math and I realized that it would take a trim of 36' (because of the distance between the wall and the electric (18"). Well we got it out to the max trim, and I catch the top of the scenery lightly, but it still works.

    So in other words no scenery section = no lighting section (although I am going to draw one just to complete my paperwork).
