    Canopy Family

    This is a pretty basic question, just want to find out the best way to do it.

    I'm creating a canopy family. Imagine the canvas topped canopies one would see at a car wash. We buy these canopies in 30' sections.
    So, if we need 120' of canopy, that's 4 sections.

    The issue is with the columns. Obviously, it's easy with one section. You have columns on each side, so let's call it 2 sets of columns. But, once you get into multiples, you now have an odd set since 2 adjacent canopy sections share a column.

    So, what's the best way to do this? I was going to array a nested family, but what about the odd set of columns? Visibility parameter to turn them off? 2 nested families; one with both sets of columns for the start, then array another nested family that only has one column?

    It seems there's many ways to handle this, but which way is best? Not to mention that, technically, the column placement is slightly different on the ends than it is in the middle, where the column is shared. I won't be building off these, though. It's just for representation and renderings, so it shouldn't matter (I don't think).

    I would do the columns seperately from the canopy - but I'm not so good with array formulas

    The way I've done them is to model both pairs of columns, visibility parameter for the one on the left. Canopy overlaps at the tie down points very slightly or not at all when two are placed adjacently.

    Similar to what they did for this company. Apollo Sunguard Systems, Inc. | awnings and covers

    Model them as sections, one canopy per section. So the first section has both columns, being the "master" canopy. The rest are add-ons. This way you can adjust each one individually (column placements, column adjustments, canopy sizings).

    You can set it up in an array if you really want to. Instance params for colLeft and colRight, and the first instance ISNT in the array, and it has colLeft on, AND colRIGHT on. Second one is the start of the array, and it only has colRight. Then you dont need to worry about IF statements. And, youve also now taken care of the "array value less than one" problem since you placed the first instance. Tell the array to use one IF statement, for arraycount= if(Count>2,Count-1,2), then have a yes/no param for ArrayVis=Count>2. Have a second individual instance with ColRght checked, placed at bay 2 spot. Its ONLY visible if COunt=2, since the array will default to 2 (which is three), and the array wont be visible. Works in all cases.

    Wow, I think my hair is on fire. I'll have to read through that a few more times.

    While we are talking about canopies, how would you model the yellow canopy part? I thought "I know, I'll use an adaptive component family". I've never used them before, so I jumped in, figured it out. Then, I found out I can't nest it into my canopy family.

    I also tried creating a few RP's parallel to the slope of each part of the canopy. 2 problems:
    1. I can't join them and the ridges won't meet up because the canopies edges aren't plumb cut (because of the angle of the RP). Without them being joined, there's a small gap at the ridge. Looks like carp.
    2. I can't get the canopy to behave and flex properly.

    If only I could use a roof in a GM family.

    I guess I could draw a big block, and use a bunch of voids to carve it out. That can't be the best way...

    So, how would you do it, sir?

    Do you need the drooping effect? If not, a simple sweep will suffice.

    Nope, not worried about the drooping effect. I originally thought of a sweep, but dismissed it in my mind thinking it wouldn't work. I never actually tried it. I'll give it a go. Thanks Andrew.

    The sweep can work WITH the drooping effect, but an Adaptive Component can be a little more realistic, in terms of droop.

    I tried the adaptive component, but couldn't nest it into my specialty equipment family. Are you suggesting I do the entire family as an adaptive component? Or, do you know some cool trick I don't know about?

    Hmmm, can I nest the specialty equipment family into the adaptive component maybe??
