CAD drawing of a bird aviary concept

We would like CAD drawings of a bird aviary concept that we can take to fabricators for them to produce a prototype. The aviary will be of metal (aluminium or stainless steel) construction and involve two different mesh sizes.

The design needs to incorporate a sloping, clear acrylic, roof to ensure rainwater run-off and at the same time enable maximum light within the aviary. The aviary will be free standing and will measure approximately 6 feet tall, 4 feet long and 3 feet deep.

We envisage that the design process will take approximately 10 hours including 3 iterations.
