iLogic standard grating dimensions

[Anonymous]

Hi

We use standard plastic grating.

And we always cut them wrigth beside the ribs to have a clean cut.

I want to made a iLogic macro that alway display the good dimensions for the cuting placement.

I found this: "d0 = Round(Round(d0,4) / inc) * inc" in the Inventor help, and my "inc" = 1.5 inches.

My problem is that my first grating square is 1.625 inches.

And this makes my macro to always updating my final value.

What is the best way to do this.

Thanks

Hi Sprocket107,

Can you share a file or screen capture of your file?

I hope this helps.

Hi Curtis

Of course, there it is.

Thanks

Hi Sprocket107,

Attached is an Inventor 2015 file that is close to what you want. I didn't get your spacing exactly correct, but it should provide an example of how to set this up.

Note there are event triggers that open the form when save or open the file.

I hope this helps.

Hi Curtis

I'm sorry, I wasn't clear enough in my explanation.

I want to work directly in the parameters box.

I have a user parameter named GRATING_LENGTH

I have another user parameter named GRATING_INCREMENT wich is equal to 1.5 inches.

But my first square is equal to 1.625 inches.

I want to use the formula "GRATING_LENGTH = Round(Round(GRATING_LENGTH,4) / GRATING_INCREMENT) * GRATING_INCREMENT" or something like that to make my user parameter "GRATING_LENGTH" automaticaly ajuted to the good value.

This formula is working fine if all my grating squares are equal to 1.5 inches, but it's not because of my first square of 1.625 inches.

I dont need an Inventor part, I only need a formula wich can do that.

Your iLogic Grate is great by the way.

Thanks

Hi Sprocket107,

Ahhh, I see.

Wouldn't it just be this? :

GRATING_LENGTH = (Round(Round(GRATING_LENGTH,4) / GRATING_INCREMENT) * GRATING_INCREMENT)+0.125

Or am I still missing something?

See attached file I used to test this.

I hope this helps.

Hi Curtis

No, your very close but I have tryed this and it doesn't work.

I placed it in an iLogic code and because of the "+0.125", because I want to auto-update the same user parameter and because the iLogic rules are running eache time a parameter changed, my GRATING_LENGTH is always changing.

I'm lost, but it's not a major issue.

I lived before whitout it, so...

By the way, can you help me whit my next post. "iLogic code for opening any files"

Thanks

Hi Sprocket107,

This should be doable, but without seeing your file it's hard to say why it's not working.

I hope this helps.
