IF Length parameter

mbiAK7WZ — Fri, 16 Sep 2022 07:20:14 GMT

Hello again.

I am currently making a family, and have problems with the IF parameter on the length. I need the paratmeter ''Altan bredde'' to have the length, 3290mm, 3380mm and so on up to 4500mm, but i cant get it to work and looked at many different sites to get to know how it can be done

So far i have tried '' IF(length 3200mm, 3290mm, 3380mm) and IF(Altan bredde 3200mm, 3290mm, 3380mm) and IF(length < 3200mm, 3290mm, 3380mm) and IF(Altan bredde < 3200mm, 3290mm, 3380mm)

I hope you can help

I have link the file here to.

I don't see Length parameter in your family.

Altan bredde, altan dybde should be length parameter, if i change the dimensions on them it changes the drawing, im far from done with parameters, but i need to get If length parameter on the dimensions i mentioned.

If you have a solution to make the parameter the way you are thinking, then i am open for it

Thanks

Let's say, if you input the value 3320, do you want the length to become 3290 or 3380?

3380

Add Length_Input parameter. Your formula for Altan Bredde should be like this:

if(or(Length_Input<3200,Length_Input=3200), 3200,

if(or(Length_Input>3200,Length_Input<3290,Length_Input=3290),3290,

if(or(Length_Input>3290,Length_Input<3380,Length_Input=3380),3380,

...

4500)))

The ... is for you to continue to develop until it reaches 4500.

By the way, your family is super heavy.

See my revised formula. Yours is missing the last value 4500 so the syntax is incomplete. copy paste ithe one below to yours.

if(or(Length_Input<3200,Length_Input=3200), 3200,if(or(Length_Input>3200,Length_Input<3290,Length_Input=3290),3290,if(or(Length_Input>3290,Length_Input<3380,Length_Input=3380),3380, 4500)))
