SOLIDWORKS version:
Sytze Spijksma - Group leader Mechanical engineering - DEMCON
European engineers love DIN standards, but most DIN standards were withdrawn in 1992. Most of them have an ISO replacement.
We only offer fasteners for active standards because we purchase the standard document and use it as a source for our fastener models.
Lock and spring washers do not work well so their standards are withdrawn without a replacement.
We were tired of scrolling through endless lists of fasteners in SOLIDWORKS, so we built Lightning. Lightning makes it easy to add, edit and replace fasteners.
Just open the filter, pick a type, size and material, then drag the file into your assembly. Lightning will add a washer and/or a pattern for you.
