Hi Guys, 

I am having issue with Camduct 2015. I've been adding a straight duct into my part list with a dimension of 820mm * 400mm * 1200mm long. However, camduct only shows an area of 2.440m2. Which, if you calculate, you will find that the area of material used will be 2.928m2. 

I've already set wastage to 0%. So I really have no idea what's wrong with my config and will there be any issue with other parts where the cost is dependent on the area of material used. I've checked the development page and the area shown is 2.928m2 as well. Unless I'm misunderstanding the area shown in the Quick Take Off Thread. 

Your help is much appreciated. 

ps: I've set the board to a thickness of 0mm as we use outer dimension here. The actual thickness of the material is 20mm. If anyone has any idea how to set camduct to take my input as outer dimension, that would help a lot as well. 

pps: We are in the process of evaluating this product for our production. Much help appreciated.
