Hi There,

I have a problem when entering straight duct (GI) for ex: 1000x1000, 1220 length, ideally should give 4.8 Sqm, but I am getting only 4.08. When i ran couple of example i found that CAMDuct is calculating 200mm less in length, ie; when my auto length is 1220, but it is only taking 1020mm. Anyone had similar problem.

When I add additional item with short length (for ex: 500mm) with the same duct size, i still get the same area.

I have attached the a screenshot...

Any help will be highly appreciated.

Thanks,
