Q1
Even if I put commercial software on the market using "Open Cascade", isn't it necessary to report to EADS Matra Datavision?

Q2
Must I pay EADS Matra Datavision money?

Please give me advice.

Only Matra Datavision can answer to that. I think you have to pay money for the components that are not open source.

The Open Source part of Cas.Cade(i.e. OpenCascade those you can download freely) is free for both commercial & open source development,and it is licensed like LGPL.

Thank you for advising me.

Is it no charge except "ssp", "Mesh", and "Option Data exchange" which are indicated by "http://www.opencascade.com/open/"?

The open source of Open CASCADE code downloadable on-line is free of charge and you need not pay run time licenses and royalties to Open CASCADE when you market your application.
In addition there are advanced components (including Advanced Data Exchange and others) that are provided on a paying basis. Please consult http://www.opencascade.com/gallery for more information.
