Hello Mr Brown,
Thank you for your answer.
Yes, I defined a mixed shell with solid... because is what I saw in this post:
Re: Creating a part with multiple material layers (Mats Lindqvist)
I explain you:
1st: I need build a laminar solid of 1mm. But using Shell properties with layers of 0.25mm
2on: Each layer with different direction and same material
Using the same example as Mr Mats Lindqvist... I believed understand that the procedure was correct for calculation.
Br,
Gorka
