Sum elements of a list

Hello!

I have a list of area elements and I want to sum them and take a total amount. Could you please help me with this?

Thank you!!

It sounds like Mass Addition is what you’re looking for.

Thank you Louis!

However it doesnt seem to be a logic result

Looks right to me, doing a back-of-the-napkin-windows-calculator-rounding-to-one-decimal check.
What number were you expecting?

Yeah maybe you are right. I confused cause of the point between the numbers which is the same everywhere

Yeah scientific notation will mess with you that way :slight_smile:

I have similar issue but mass addition doesn’t work. I want to display sum of all curves length.

Flatten the length input going into Mass Addition. Otherwise, it treats each entry as being on a separate path.

Thanks!

thanks bro
