Parametric Cabinet with max door width constraint.

TAZ-ZA — Fri, 11 Feb 2022 08:11:25 GMT

Hello - please help!

I’m trying to create a parametric cabinet which has the following constraints:

Height, width and depth all parametric.
Cabinet doors to be a max of 450mm
If width of cabinet exceeds a multiple of 450mm then doors must divide equally by the width.

E.g. if the cabinet width is 1200mm then each door would be 400mm wide.

So far, I can flex height, width and depth. Cabinet doors also flex, but exceed desired max 450mm width.

Any advice would be fantastic. I’m more than happy to share with the community if I can figure it out.

Thank you.

Add a formula to control the Array Integer parameter: = roundup (Width/450)

@TAZ-ZA

You model the door in a separate family and nest it in (associate with parameter align and lock ...etc) where the Panel Width = if(P1, 450, (Cabinet_Width - Joints) / Array)
Then you need to place 1 instance for when the width is 450
- give this panel a visibility parameter P1 = or(Width=450, Width<450)
Then place a another instance (the one you will array).
- Give this panel a visibility parameter P2 = not(P1)
- Array, label and Lock it as needed
- Set the Array = if(P2, roundup(Width/450), 2)

Alternatively, and if you are working with 1 to 3 panels, it might be easier and lighter to just nest 3 types of panels (single/double/triple door) and either control these using Y/N per cabinet type or using a Family<Type> label controlled by cabinet width

Thank you @RDAOU and @ToanDN. I couldn’t make that work for me unfortunately.

I just want to clarify the steps I’ve taken.

Modelled a door in a separate family making the width parameter instance based before loading it into the carcass/shell family.
Locked door to reference planes in the carcass/shell family and made door width = Width/Array
I applied a visibility parameter to that door (Yes/No, Visibility) - (P1) = and(Width=450, Width<450)
I placed another instance of the door in the same place as the first door and locked it to reference planes.
I applied visibility parameter (Yes/No, Visibility) - (P2) = and(Width=450, Width<450)
I arrayed the second door and placed the following parameter to the array: if(P2, roundup(Width/450), 2)

When I flex the width, the door just stretches and overlaps the first door.

@TAZ-ZA

P1 formula should be or(Width = 450 mm, Width < 450 mm)
The formula you entered in P2 is wrong ...should be not(P1)
And you need to lock the array properly at start and end
And Door width formula needs to be if(P1, Width, Width / Array)

You're a saint. Thank you so much.

@TAZ-ZA

You are welcome...other things you need to fix

The door doesn't need to be casework...you can change its category to generic model
The Height, Width, Depth in the door you can change to Type parameter (you need instance only if you are using shared components)
You also need to Associate the Height of the door to that of the Cabinet

@RDAOU

Thanks, I manged to follow along and learned some new trikes today.

I'm now trying to have the a truly parametric cabinet but when I change the height of the cabinet the doors don't change height with the cabinet.

Can you please advise what I need to do to make this happen?

Many thanks
