Save unfolded Length in to user Parameter

[sandip452]

Hello All,

 I need help from an expert. I have one simple C-shaped sheet metal part as shown in the image. I have one user parameter, So My question is I want to save the unfolded length of the sheet metal part into the user parameter (fraction). The only issue is Flange 2 length (X3) is dynamic And it's changing due to other factors. Thanks for any help.

I don't know what is the reason. But you can't obtain the unfolded length as parameter (with immediate update) because it can cause circular reference.

You can update the parameter value on demand (for example on save document) and update appropriate parameter value.

Or in some cases you can calculate the final length manually. When you use kFactor (or wiki page)for calculation of flat pattern

X1 + X2 + X3 + 2 * LengthOfArc
