Parametric Arrays in Revit Families!

[@dusanstevic89]

Another great video packed with solutions to real world problems. A true gem!

[@AussieBIMGuru]

Glad you enjoyed it!

[@WindGazer01]

It's an amazing video!. I am a jumior Structural Draftsman and I subscribe and watch your video session all the time when I am stuck with something. I appreciate your effort!

[@AussieBIMGuru]

Awesome - glad to hear the content is helpful for other disciplines besides my own (architecture)!

[@qingyangpan78]

You blow my mind!! Keep it going mate!!!! Shout out from France

[@AussieBIMGuru]

Thanks, will do!

[@FrogieFishOfficial]

Amazing tutorial ! I had to watch it at 0.75x the speed. You are so fast on Revit

[@AussieBIMGuru]

Yep many viewers watch me on 0.75 and 0.5, although i sound drunk at half speed haha. Glad it was helpful!

[@AhmadChesti]

Great series. Very helpful. Could you please show if we can make a parametric array in which the last element is a part of the first element. For example, I need to fill a room with tiles of fixed dimensions and I need 5.3 tiles on one side. Is it possible?

[@AussieBIMGuru]

Its not possible within a single array unfortunately. You would need a spare adjustable tile on the end that fills in the excess left by the arrayed tiles.

[@AhmadChesti]

@@AussieBIMGuru Thank you so much for the answer. As you know the new element appears when the length increases by 50% of the element length. Can we change it so that it appears say, when length is 70% of element length? for example only 5 tiles of 1m in length of 5.6m but 6 tiles in length of 5.7m.

[@AussieBIMGuru]

@@AhmadChesti yes you could do this using a formula for the count with a max spacing, where you use fixed spacing and an excess instead of equal spacing. It's mainly just a matter of drawing up your goal and applying some algebra to determine the needed formulae.

Great video. It would be amazing to have cheatsheet with all the options!

[@AussieBIMGuru]

You can find my presentation PDFs on my github if they help

[@ericphm9984]

Great tutorial, thanks a million!

[@AussieBIMGuru]

You're welcome!

Have you discovered a way to make arrayed nested families change their height as the array increases in length?( The first in the array is length X, then the next is X+100, third is X+200 for example)i am fighting with this concept currently. It's for sheet piling, I have set up a family that arrays them, and all their lengths can be changed and rounded to a standard size. But i'd like to be able to increase the length of the sheet as the array progresses (for example an embankment that gets steeper and requires longer piles) and control it with parameters do you think it's do able? Could adaptive families be the answer?

[@AussieBIMGuru]

Adaptive families would be needed here or a dynamo script for parametric placement. Unfortunately arrayed objects generally have to be the same in all aspects including spacing.

[@A_SENTIENT_BIN]

@@AussieBIMGuru thought that might be the case! Cheers for the reply though mate.

[@danielarmenta8235]

Thank you very much!

[@AussieBIMGuru]

You're welcome!

[@vltucker2737]

It would be helpful if you opened the Family Types Dialog box so that we can see the whole Formula that you are inputting, if you don't want to make the dialog bigger for whatever reason, you can make the value column smaller.

[@AussieBIMGuru]

Good tip, thanks!

[@ScottValentine]

So I tried this out with the shelves. But snapped and locks the Width and Depth of the shelves to reference planes. It didn't like it. Nested families never seem to want to stay locked to reference planes in my experience.

[@AussieBIMGuru]

Snap them from the nested component origin planes. Any others and the parameters will trump constraints

[@ScottValentine]

@@AussieBIMGuru ok so I locked the origin planes and then controlled the shelf with a formula. eg = Width - ( Carcass Thickness * 2) Seems to have worked. I don't know why they can't make these things more logical and user-friendly.

[@AussieBIMGuru]

@@ScottValentine yeah there's quite a lot of idiosyncratic aspects of family creation in Revit; takes time to come to terms with all the little tricks and workarounds! Once an element is arrayed it can't be constrained by more than one reference plane in any one direction unfortunately.

[@sandeepjadhav19854]

Hii..I made this family nice work..I want to make vertical alignment nested family regarding Helical pile..can you make video.

[@AussieBIMGuru]

Vertical alignment would be similar to the way i did the bookshelf. The helical pile would be difficult to constrain, it would require an adaptive/conceptual form because the blade is swept in 2 directions.

[@sandeepjadhav19854]

@@AussieBIMGuru Thank you..I tried on Adaptive component..but still not work..

[@sandeepjadhav19854]

I made component like pile extension, Helical plate but when I merge into 1 file..it's not work..

[@AussieBIMGuru]

[@vinayck855]

can able to do ladder consist of hoop's in parametric

[@AussieBIMGuru]

Yes this would probably be best done using two arrays for the staggered effect of the two sides of rungs.

[@vinayck855]

Is there a complete vedio of this step ladder ?? If pls share a link of that vedio

[@AussieBIMGuru]

Not in this case, but it uses principles shown in the video generally.

[@vinayck855]

@@AussieBIMGuru can u able to give than family pls ...or pls do a vedio of that it will be helpful

[@AussieBIMGuru]

@@vinayck855 I don't make videos currently due to time limits but I added a ladder here that follows this principle. It relies quite heavily on trigonometry to work: github.com/aussieBIMguru/Revit-Files

[@shanD7]

my mind cant grasp all these, lot of information & formula, need to rewatch it many times...

[@AussieBIMGuru]

Good thing it's replayable 😉

[@ashrafulalam7042]

Sorry you speak too fast which is not good while teaching someone!!

[@AussieBIMGuru]

Try x0.5 or 0.75 video speed. I have quite a few viewers who find this helps. Unfortunatelt I only get limited time to record, but I have worked on my diction a bit more in recent videos since this one.
