Select the target surface where circular shape is present and edges from circular shape (closed edges domain) .

Number of Layers

Specify the number of layers to be offset (minimum value 1).

Total Layer Height

Specifies the height of the total number of boundary layers.

.

Layer Growth Rate

Proportionally adjusts the height value as the layer advances  when the number of boundary layers is 2 or more.

Ex)

 When 1 is input, it is represented by the same height.

 If it is larger than 1, it becomes larger.

 If it is smaller than 1 a layer is created with increasingly smaller heights.
