Wait is that the same Dassault that makes french weapons and planes?
Not directly the same company, but they are under the Dassault Group. The aerospace group developed it, and spun it out.

Shapr3D https://www.shapr3d.com/ … not free.
Also simple 2D CAD Qcad - www.qcad.org and its spinoff LibreCAD - www.librecad.org .
Applying the concept of ‘boycott’ to gratis and libre software with no profit makes zero sense.
What FOSS CAD-tools are being boycotted?
