I have never used the Thicken command while sketching in Sheetmetal until today. I know what my material thickness is, so I Thicken by that amount. I see no dimension show for the Thicken feature??? What happens if someone changes the material thickness in the future? The user would not know the sketch with the Thickness feature was created at the original part thickness. Seems to me as though Parametric went out the door with this command?
