Help here...

Is it possible to create a project based on blender that uses, lets say the interface components?

I mean like a whole new program (Blender office, for example) that uses the code of blender for the interface…
I don’t know if this is the right place…

If you mean - can you create interfaces for Blender to allow extra functionality - then yes, using python scripting.

If you mean - can you manipulate the properties of objects as though it were done through the interface - then yes, through python scripting.

If you mean something else - then please rephrase the question.

Oh, and post it in the right forum next time - like one of the help and support ones…
