Hello, I am desperately trying to sweep an array of geometry with no success. I am trying to create a circular fan grill where the number of circular wires varies depending on the grill diameter. The only way I could think of to accomplish this was to attempt to sweep an array of circular profiles using a circle as my path, but I cannot figure out how to select the array as my sweep profile. I have tried creating the array of circles and then sweeping it, and I have also tried making a separate Profile family containing the array and then loading the Profile during the sweep operation. The second method seemed promising, but when I loaded the Profile, it only included one circle instead of the array of circles. Please Help!!!

In the attached image, you will see what I am trying to achieve. I have created the fan grill using three separate sweeps of one circle, but I would like to be able to control the number of circular supports. In this image there are three (3), but for a larger grill there might be five (5) or six (6). Thanks in advance for any advice!

The profile has to be one, closed loop.   An array will not work so you will have to find a different way.   Perhaps individual sweeps.

Darn, I thought that I could assign an array as a profile since when you edit the profile during the sweep command, it allows you to draw a profile that can include multiple closed loops (see video attached). If I were to try this using separate sweeps, would there be a way to control the number of sweeps using a family parameter?

Not exactly the number but individually you can set a condition for the inclusion/exclusion of every element in a family.

Ok, I thought about that but it became more about the principal of the thing! It just seems like there must be some way to do it that I'm not thinking of.  BTW, sorry the video didn't load, try this link instead...

Sorry - I was stupid in my earlier response.   You can have multiple loops but they cannot intersect.  I still don't see any way to use an array but I personally have not tried that - yet.  in 10+ years

Nuts, that would be a nifty feature. Thanks you for your help!

It would seem revit does not deal with arrays within profiles very well and always defaults to using the sketch element that is furthest away from they origin point of the profile. Since you need this sweep to be circular I do not think there is any way to acheive this. The only way I can think to sort of 'fudge' it is to either use a revolve and have several circles for your profile aligned to equally spaced reference planes and then have a visibility parameter that turns the profiles on and off or to create several circular sweeps for each ring controled with visibility.

Hopefully revit fixes this issue with arrayed profile familys.

Is it possible to Extrude a 2-D profile as a sweep in a Revit 2016 LT project?
