Array Based Families in Revit - What You NEED TO KNOW!

[@realblackmonday3563]

Great Lesson. 14 years experience and learning still everyday. Thanks

[@TheRevitKid]

Cheers! So glad you enjoyed ! We can always learn something new! Myself included!

[@Zomer2003]

Oh GOD, how thankful am I!!! I was trying to make this adjustable pedestrian crossing for a day and now it's finally working! Only one thing that was not in the tutorial and I spent time to discover myself, is the centerlines of the box to align with. I just did't have those... In the end I set the reference planes inside the box family to the "center" parameter and after reloading the family in my working file I was able to finally align the box to the refference planes...

[@TheRevitKid]

Glad it helped!

Finally, a Revit video with decent sound quality!

[@MLangjahr13]

This was an awesome lesson!! I used it to make some rods for the hanging of a track lighting. So the longer the track the more rods for it to hang

[@TheRevitKid]

Cheers man! Yes, tis would be GREAT for tracks and rods...

[@leben1841]

Very good. Aligning to the centre is definitely a great tip. The stair stuff almost killed me a million times. Thanks a lot Jeff.

[@TheRevitKid]

Those freaking "Stair" arrays! Brutal!

[@bimskool]

This is going to be great for switchboards and MCCs. Yes some sections realistically are different sizes but that only matters for LOD 400

[@bdoggb2408]

Great tutorial! How can I do a stacked array with horizontal & vertical options for a single row? Thanks.

hello i have a problem finishing a family (movable wall) very detailed and i was hoping if you have a video that explains such a family ???

[@TheRevitKid]

You'd need to be more specific than that...?

[@PamChaiyachakorn]

Hi! I've nested this box array family in another family. It's a radiator with valves that stick out on the sides of it. I'm having difficulty snapping to the center of array to the rest of the nested objects. Do you have any advice for this?

[@athulsvi8778]

Great presentation. Wt if there is a fractional number in case of no: of boxes? Or is there any way to get the boxes get trimmed at the ends, (for use in railing) ?

[@TheRevitKid]

I wouldn't suggest using this for railings as their are other methods to do so... As far as fractional number of boxes, no. You can't have 1 1/2 boxes. You would have to have some visibility paramters built in that show the last box as a half or something interesting like that!

This really helped me! Thank you, sir!

@@TheRevitKid i have been trying to create a family with varying voids using an array when I loaded the family to another family or project and changed dimensions Revit says "A group member's sketch or family is constrained to an element that is not a member of the group. These constraints have been removed." my approach is Sometimes when making an array of some kind of specifically constrained geometry it is easier to make the arrayed element a nested family. That way the family itself can control the geometry and the constraint condition of the array is easier to manage as it is now only constraining position However, I use an array of void elements which can not be loaded as a nested family.) What is the best approach for this?

[@TheRevitKid]

The first question I have is why are you arraying a void? can it be done with a solid or different approach?

[@AirV5]

Is it possible to use this theory for window & door mullions as a type parameter? With the only controls being the size of the window/door, the size of the mullion, and the # of mullions(equally spaced) And if so, could you make a video? I'm struggling to make it work. (I know this works in a curtainwall system, but would like to use in a window/door family were I only create 1 family and have many types with different parameter settings)

[@TheRevitKid]

100%, yes it is possible! But depending on your situation it may be a curtain wall system that makes the most sense...

[@prestonbaird6503]

I feel like I am trying to do something similar to this. I am trying to make a trench drain with a set width of bar and set distance between the bars, and an adjustable overall length of the drain so it can be long or short depending on the distance of the opening in the floor. I want to keep the spacing between the bars the same and keep the bar size the same regardless of the total length of the drain, and if I were to stretch the drain length to be longer, have it create more equally spaced bars, and if stretched shorter, to reduce the number of evenly spaced bars to remain within the space created by the length of the line. Is there a way to do this by telling it to array into infinity but be defined by the length of the drain so that it only creates more bars within the defined length? Great video and I feel like some of the methods in it could be used in the issue I am trying to solve, just not sure how. Thanks!!

[@malasuerte6714]

plz make a tutorial for making partition wall family which may contain 3 layers like wooden frame in middle and MDF sheet on both sides. for BIM, if you edit the type of wall by just layering that simply you dont get the perfect BOQs, like surface area, no. of sheets and other stuff.

[@TheRevitKid]

Do some research on Parts for Revit. You'll get the best of BOTH worlds.

[@sallyvandal8453]

Hi there. Great video. I wish to use an instance parameter for a specifically sized locker. I can't seem to get the array to be associated with the length of the line. I'm guessing there's a formula I need to put in, but I'm not sure what that should be.

[@TheRevitKid]

Depends on what you are trying to do... if the width of the lockers is determined buy the number of lockers then it is a formula along the lines of (Width = Length/Number) if its the other way around then its (Number = Length/Width)... If that makes sense...

[@GarthEdmunds]

Good day Jeff, is there such a thing as a partial array? So on your blocks that are arrayed and the gap between them is zero. When you draw out the line for the boxes at the end of the line would be a partial box as the line wasn’t long enough to complete a full box.

[@TheRevitKid]

That's a bit more challenging but it can be done. You'd most likely need that box to be its OWN element (not part of the array) and use a ton of formulas to work out the rest...

[@AhmadChesti]

Great video. 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? if not how can i do this parametrically?

[@TheRevitKid]

I am not sure what you mean?

[@AhmadChesti]

@@TheRevitKid For example I have a room 5.3 meter wide. My floor tiles are 1 meter wide. I need 5 tiles and 0.3 m tile. How can we do this parametrically?

[@TheRevitKid]

@@AhmadChesti You'd have to build it so it creates 5 and then the visibility of the last one turns it on and sets it to the width you want... the last one would not be part of the array.

[@AhmadChesti]

@@TheRevitKid Thanks so much for the reply. As you know the new element appears when the length increases by 50% of the element length. Like when length is 5.4, there are 5 tiles, when it reaches 5.5 it add 1 tile. 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.

[@TheRevitKid]

Yes, it can all be done but with lots of formulas!

If we giving formula to that number of boxes ex(length/spacing) means. How to control array less than 2 ..is this possible ?

You have to use visibility parameters and have a single box tube on whole the two boxes turn off!!

I'm trying to make a parametric Air Handling Unit, which consists of several sections. I'm looking into the possibility to use an array for this, because the number of sections varies from one Air Handling Unit to another. This video seems like a really good start. I figure I can use a nested Family Type Selector in the array to be able to select different types of sections (filters, fans, heating coils, etc). The problem I foresee is that the different section types will have different lengths. This would result in gaps or overlaps between the sections. I'm guessing I can use an 'offset' parameter to move the section back and forth from it's 'array center point'. To be able to calculate this offset I'd need to know the sum of the length of the previous sections in the array... can this be done?

[@TheRevitKid]

Mark, yes... It sounds like you will need to build this in and have the offset adjust based on the length of the types... It's challenging but should be do-able... good luck!

Can you make a video how to make bricks in array line base family

[@valeriepierre7297]

it's the same process just use the size of the brick for the box width

[@facelessone86]

Is there a way to get the length parameter to not be greyed out? It makes editing some things difficult if you have to rely on only the grips.

[@TheRevitKid]

When the object is line based the length parameter is driven by the line (grips). Not sure what you are trying to make but it may be better for you to start with a generic template (not line based) and add a length parameter that is an instance...

[@facelessone86]

@@TheRevitKid I was able to make another length parameter and set the built-in to be equal to that parameter. I still get the grips but then can also enter in a length.

[@TheRevitKid]

@@facelessone86 Yup, that is an option, too! Glad you figured it out!

[@facelessone86]

​@@TheRevitKid If I draw the element 12 feet long and then set the length parameter I've made to 10 it works well, but if I move the element it will remember the 12 feet and change the length back to that. Not sure exactly what is going on with it.

[@forename_surname]

Do I need to watch this twenty times before understanding why the box centerline to box centerline measurement is called "Box Width" even when the space between boxes is more than zero, and the distance is clearly NOT in reference to the box width... learning hurts sometimes.

[@TheRevitKid]

So.... you GOT it?? :)

[@EliasDaoud-ty8pf]

I am suffering from scalable or parametric shape of an element of an array in a family. First it work, then adding or solving another issue, it stopped working. Let's talk about your example (mine is sound attenuator), if you want to let your shapes or rectangular ones, to be scalable, such a parametric length (with a formula) how todo that? Revit replied to me (in my family) that he cannot because the parameter has a formula, (where before he accepted). I hate Revit detailed families LOOL
