Can you explain in detail the purpose of the request?

If you want a wall made of transparent glass there is a special window made of glass blocks, or you can create your own with 3D modelling software like Blender.

If instead you want to hide a wall to better view inside a room you have several options:

• change the wall height to a lower value;
• use transparent boxes to cut out parts of the wall;
• use Pan3dView plugin which has a feature to automatically hide the walls that obstructs the view.
