Frequently asked questions
What is WSi?
WSi is software for costing and work preparation of sheet metal parts and assemblies. It reads CAD files, breaks assemblies down into single parts, lays out every manufacturing step, and calculates times, costs and tiered prices from that.
What is Costonaut?
Costonaut is a CRM for sheet metal manufacturers: software that keeps customers, contacts and requests in one place and carries every request from arrival to accepted quote. It collects requests from email, upload and web form, calculates them and turns the bill of materials into a quote your customer accepts online.
What is WSi Shop?
WSi Shop is your own online shop for sheet metal parts: your customers upload STEP or DXF files, choose material and finishing and see their price at once. WSi calculates every part, and WSoptics runs the shop on its own servers at its headquarters in Germany, under your domain.
Can WSi cost entire assemblies?
Yes. WSi explodes whole assemblies automatically and categorises sheet metal parts, tube parts and purchased parts, without you having to break the assembly apart by hand.
Is there a free trial?
Yes, WSi can be trialled free of charge for 30 days. Any customisation made during the trial carries over when you move into production use.
What happened to WSi4?
WSi4 is now called WSi. It is the same software under a new name; existing licences continue unchanged.
