Good morning, how are you? I'm practicing with Camduct to later apply it in my company. I have many doubts, and I'm not sure if there is any training available for the entire program because I see in the forums that it's quite extensive and complex.

My question is, I'm trying to get the program to give me the value of a piece based on the material cost and the weight of the piece, but when calculating the area, it calculates it incorrectly. I'm not sure if I activated or deactivated some option. In the images, I'll show you what I mean.

When designing the square piece, it gives me an area of 13.7 sq ft, but when it comes to costs, it calculates an area of 4.27 sq ft. I don't know how to configure the cost area in Camduct. If anyone can help me, I would be very grateful.

Thank you very much for your assistance.
