I have a .urdf.xacro file where a particular xacro macro has been defined with a few parameters including - "mesh". When I instantiate this particular macro in another file, I wish to leave out the "mesh" parameter and instead define a shape (like a rectangular box) of my own.

Is this possible at all?

The xacro converter seemed to be quite literally to me, but you could look at it's source.

Or you could remove mesh/shape from that macro and make two macros extending the base macro for both mesh and shape.

And mesh="" won't work?

I will look into the source, thanks! I tried mesh =" " but that didn't work because it searched for the ".stl" file (no name extension). I will check if modifying the xacro works or not. Thanks again!
