Thank you Tom for the reply
I have another developer of Genuis 3D. Its a proprietary code so far, but they have plans of open sourcing it. However, the developer mentioned that it will be GPL with some additions. I guess that would make it GPL incompatible.

Ziyad,

It is permitted, but it is worth mentioning that because of the
"advertising" clause, this license is GPL incompatible, which may cause
problems with other software.

The original author of the BSD license (Regents of the University of
California) has stopped using the advertising clause, and has withdrawn
it from all code for which they are the copyright holder. I would
strongly advise the NanoTCAD developer to also drop the advertising clause.
