I am using su 2020
But I need to save file as 2015 version everytime
Because most of co-worker using 2015
It is too inconvenient
Is there an extention that help this problem?
Like autocad
Go into option and setting save version
Maybe Eneroth Legacy Save from the Extension Warehouse.
@Renderiza 's Allsave Plugin
or Maybe @eneroth3 Newer version could help you
