Boolean tool on imported objects

[Anonymous]

Hello,

I am beginner in using 3ds max so please excuse my dumb question.

I am trying to grave an object from another object, both of them created in another 3d modelling software, from .OBJ format.

It is a signet ring and a relief griffin.  What I want to do is graving the shape of the 3d griffin into the plane surface of the ring.

I have tried to use the Boolean tool but without success.  I am sure I do some mistake but I don't know what.

And this is look like after using the boolean tool:

I have tried also the ProBoolean but it gives me Invalid boolean.

Is there any setting that I should change on the imported objects?

I tried  the Boolean tool on some rectangles and shapes created with 3dsMax and is working fine.

Thank you

Unlike many CAD packages that deal with solid objects ( Solidworks - Inventor ), the booleans in 3DS Max deal with surfaces, so if the surfaces of the two don't overlap, all boolean operations ( except for union ) will have no effect.

Thanks for the info!

is there any chance to convert solid objects to surface only?

Well Yes, typically when you import a solid part ( for example from Inventor ) you are given the option to convert the import to mesh or import as a body object.
Also, if you already have a body object in the scene - you can R-Click and convert to editable poly. However, your previous post said you were importing a object - I don't think that would be a body object or solid - objects The file .OBJ ) are typically Geometry files.
