Hi Shafeek,

To set up your sub method:

– create a copy of the nearest existing method ie one of the H methods

– in the use the Order Priority section click Top to select it, 

this should make the Top pink in the drawing

-Click the UP arrow several times until the Top moves to the top of the list and the drawing shows it Over Passing the sides

To get the bottom raised by 100m :

– in Recess and Overlap rules clcik the + button to add a rule

– in Parameters, Over Passing panel list select the Sides

– in the Under Passing panel list select the Bottom

– in the Propetrise list set Overlap to 100

Your drawing should look like this:

You can rename the sub method to suit.

Hope this is helpful.

Best regards,

Ness
