▪ 2.0 * Thickness—Adds a relief with a width equal to twice the thickness of the sheet metal wall.
▪ 0.5 * Thickness—Adds a relief with a width equal to half the thickness of the sheet metal wall.
▪ Gap—Adds a relief with a width set by the SMT_DFLT_CRNR_REL_WIDTH parameter value.
b. To change the corner relief depth type, select a different type from the Depth list:
▪ Blind—Adds the relief according to a specified value.
