I am exploring using the battered wall accessory to represent siding applied to a wall. Since the tool eliminates openings when it is applied, it works well. I am trying to find a global parameter or a formula that will calculate the surface area of the part with the openings subtracted. I have tried all the wall surface global parameters even though it isn't a wall. I am using the REF COMPONENT command to calculate the material I want but the numbers aren't exact. I have added a variable for the siding type to be selected by the drafter. The formula below is one example I have tried but the formula needed a multiple of 10 to come close to the correct amount. This also doesn't take into account the openings in the wall. Any ideas? Thanks.

IF siding="5in Cedar V-Match" THEN
REF COMPONENT "X16010599" , "400" , ((ac_wall_height*ac_wall_length)*10)
ENDIF
