Hi,

How can I calculate the length of curves which bound a clip plane? Apparently, there is no built-in function for that. I figured that if I can extract the curve, I can use the IntegralLine function, but I don't know how to extract it!

Cheers,
Soroush

Hi Soroush,

You can extract the border of the clip as a new 1D part, and then use the Calculator function "Length", that returns the sum of all the lengths of 1D elements.
To extract the border of the clip, do the following. Change the representation of the clip part to be "Border" (select the part in the part list, then use the Part element settings icon at the top-right). Then, do Edit -> Parts -> Extract. This will create a new part that is only the current representation of the parent part (the clip). So, it will be composed of only 1D elements. Now you can apply Length to this extracted part.

Let me know if this is not what you were looking for, or if you have more questions.
Best Regards,
