How to Calculate laser cutting length ?

bedel_aras

I need to see the total length of the sections to be laser cut on a piece of sheet metal. I had to select each element individually to create the length shown in the image, which took a very long time. Is there a shortcut to this process?

Can you use Right Click | Create Selection | Loop / Chain Connected | Add Selection here?

.

You could use the new Query Variable paired with Measure Value by @Konst_Sh to dynamically get this measurement:

Or for $10 you can get a copy from fs.place that shows a toolpath and drops some estimates into a table for you.

I wondered about the need for the CF 'Measure value' and tried the regular variable feature in Measured mode. And voilà!

@Henk_de_Vlaam strange, I tried that at first but for some reason it wasn't liking my dynamic input. Did you change the input query? Is it still auto detecting all edges or did you manually select them?

@MichaelPascoe,

No, I used 'your' query and did no manual selecting.

Cool! I probably forgot to test again with the latest query. Sweet.

This method definitely worked for me. Just select each surface individually for the bent parts and proceed. Thank you.
