This is awesome. Usage of formulas in design is truly awesome.

Dude I'm going over all of your parametric tutorials. Thank you BA

Thank you very much, very clear & very useful, first time I know about the formulas inside the parameters.

This tutorial is simply AMAZING!!!!! Congratulations for making such a didactic video! Thank you so much!!!

great tutorial, this will prove very helpful as I continue to learn learn family creation for various projects

Thank you from Italy! very helpful :)

Big thanks man! from the Philippines!

Awesome Thank you from Trinidad + Tobago !

thank you for this video! I used it today in my project!

Great tutorial! Thank you.

Thank you for being a blessing

Thanks Sir, This tutorial helps me very much.

awesome tutorial from Iran & Canada! I have a question what happens when we assign 1200mm to the length? I tried if statement with >= or

That was amazing!

Awesome tutorials

Thanks from Málaga, Spain

Great job!

Thank you from Brazil..

very nice，thank u for your sharing

oww hehe i see, thank you Balkan Architect ;)

Can you show some parametric door families with architraves and some complex designs for doors. Thank you

thanku sir its really helpful..,,

hi Balkan, thx a lot for the tutorials, it works perfectly except when I changes the width of the table, it looks like the chairs on 1 side remin the same distance, so the table crosses the chairs.......

what will be the formula(syntax) used when the table length is 1200 (as the parameters given does not specify visibility when the length is 1200)

Thankyou sir you don a wonderful jon on Revit i tried that but at the end visibility parameters are not working correct it shows disappearance ticking but showing the object in drawing area.

So complicated! You have to be a kind of mini programmer just to draw tables with a few chairs. Revit should reprogram the whole parametric family creation techniques easier and more user-friendly. Spending hours and hours just brainstorming how to do a simple component is insane for most drafters, technologists, and architects.

YOU ARE VERY GOOD

Thank you from Jamaica. I would like for you to create a manhole drainage system with parametric materials

Thank you

Hey, my friend, you said the family will be available in the description, there is nothing... or I just dont see it? Thx in advance for your answer... Tomas from Slovakia

Good job

Thanks you're The best

Thanks man ..from saudi Arabia

One family and get series of table sets by setting formula for the chairs. Thank you!

nice job

nice tutorial! Will you share the family? :-)

If I change the width of the table, the chairs on one side don't maintain the same offset from table. What can I do to prevent it.

Gracias

Do you have a video a bit more complicated video like: you can merge the chair and table together to have a furniture system to then be able to change the settings/dimensions of the table and chair simultaneously + changing the table size and chair quantities within a set formula just like in this video? I see that in this video, you cannot adjust the parameters of the chair, only the table to produce a different arrangement and quantity of chairs.

Great explanation! But how do we load families into the project at the last? It says No open projects to load family into!

you are genius the revit team must put your face as revit logo

thank you for this tutorial, it is very helpful. But why do we divide it with 650 mm, where does this come from, please?

Broo...I did it well😊❤...But the conditions for arrays, side chairs and center chairs are a bit complicated and confusing...Nevertheless i did it 😊...Your are great...Hats off...I am over the moon😎

Great example of if/then statements in a family. I noticed that you did not change the width of the table. I'm guessing if you did, you would have noticed the same problem I am having with my table family. When the width changes, the chairs do not stay locked to the reference plane that is supposed to correctly move the chairs. I set up and locked the chairs exactly as you show, but changing the width only moves the chairs on one side of the table. Something about an array group being over-constrained. Any thoughts on how to resolve this?

Honestly just spent the past 3 hours watching this over and over again and doing this over and over again. I cannot get 4 chairs to show for the life of me. I don't understand the array forumla: take the length (i.e. 3') and if it's greater than 3', then divide that length by 2, if it's not greater than 3', you default to 2 chairs? Is that what I understand the formula is?

This looks like SolidWorks configurations, display states and equations, only more rudimentary.

bravo

Great Tutorial. But my version cannot hide when I turned Visible off. The chair remains visible. Care to comment. Thank you!

after making array the chair offset parameter causes error if modified. am i the only one? no, i'm not. even Balkan Architect's causes an error when he accidentally changes the chair offset at 6:41. he thought he was changing table length, instead changed the offset value, and got the same error all of us will get if we try to change the chair offset. how to resolve this error?

wonderfull,thanks from Viet nam...

great but fyi, its "height" not "hight"

Why did u choose 650 to divide

does anyone know why he chose 650?

Awesome tutorial, but its soo confusing with all the references and parameters and other things.
