The
three ducts, measuring up to 35’ across and 20’ tall, were designed on
SMC’s CAD system as 3D models. With one duct having compound angles and
the need to fabricate it in two sections for transport, the 3D CAD
models were a necessity in the design and fabrication.
|
|
|
|
The 3D models
were expressly usefully in conveying, to both the
customer and the fabricators, the intricacies of the
design so they could fully view otherwise hidden or
obscured design features. |
