From the drawing generated by solidworks, through constructions with the ISO structures module, the lengths of the different profiles can be retrieved and transferred to Excel. If this bridge is possible, I will look at the optimization with the overlengths to encompass the non-perpendicular sections. Thank you for the information.
I'm going to take the liberty of answering next to your question, but just to inform you that there are modules (software) that allow you to optimize the cuts and this not in relation to a set but a series of flows, especially with the ability to recover old drops from previous flows.
It seems to me that our favorite @ac_cobra_427 who introduced me to the thing.
Thank you @Zozo_mp , if it's for Excel there is a nice little file called optidecoupelength optidecoupelongueur.xls (125 KB) or else there is logitole and logibarre which are nice for the flow and bar.
