Add thickness to face

A thicken operation adds or removes volume from parts or adds thickness to surfaces to create parts or new solid bodies. On the ribbon, click 3D Model tab Surface panel Thicken/Offset . In Select mode, the default is Face. It specifies that only individual faces can be selected with each click. Use Quilt to select a group of connected faces with one click. In Output, click Solid. Use Select to choose the participating faces or surfaces. To select tangent continuous faces, click the More tab, and then select Automatic Face Chain. Use Solids if there is more than one solid body in the file to select the participating body. Optionally, change how approximate thicken solutions are computed. To prevent approximate offsets, clear the Allow approximation check box. To determine where the deviation is distributed, click the arrow to select from the list. To specify the accuracy of the computation, click the appropriate option. If Specify tolerance is selected, enter a tolerance in the box. On the Thicken/Offset tab, choose Select, and then click the faces to thicken. Specify the thickness. If needed, click the down arrow to use the Measure command, Show dimensions, or select a recently used value. Specify Join, Cut, or Intersect operation for a thicken feature. Optionally, select New solid to create a new solid body with the specified thickness. Set the direction of the thickness, and then click OK. If an approximation is used, click OK in the message box to accept the results or Edit to return to the Thicken/Offset More tab.

Note: To select individual faces to thicken, clear the Automatic Face Chain check box on the More tab.
