    losing units in formula

    I have a partition wall that I need to double the thickness of in scheduled thickness of our wall schedule. When I put the formula in it deletes the units because I am neutralizing the unit for calculation. How do I get the units back?

    Change your calculated value from a number to a Length parameter and you should be good.

    edit: that will involve deleting your current parameter and recreating it.
    edit2: cliff's response (below) is way better than mine.

      Not sure about the formula problem, but---
      I would just create a new Wall Type with the double thickness. Not sure why you are trying to do this from a Schedule?

        Cliff this is a response to workflow. In order to do apartment units as groups we do the partition wall as a half partition wall. In order for this to schedule the wall properly I need the full width of the overall partition which will include both instances of the wall. So no I will not ever use the full width of the wall. I don't want a rogue wall sitting out in no mans land just to schedule it.

          Why do I have to delete the parameter this is a schedule thing? What is your change to my formula? In order to get consistent units I have to drop the width with the /1" command. So you want me to do something to the 2?

            Am I missing something? To just multiply the width of a wall by 2 you do not need to "neutralize" the units. Just straight up multiplication will work just fine.

            EDIT

            Oh I see this was already proposed. You are setting the format of the calculated value to "number" that is what is making it need to be "unitless". You don't need to do that. You can just set the calculated value to be "length" and then the math works just fine.

                recreate the parameter and instead of a number, use a length parameter.

                  Right. If the "type" for the calculated value is set to "number" that is expected. You need to set type to "length" when you create it.

                    So--it's a party wall or demising wall, so you are counting "half in one unit" and "half in the other unit"?
                    That's one "workflow". But I have done many of these types of projects, and we just scheduled the actual modeled walls, and got the GC/CM involved early to explain our quantification method.
                    But, it looks like you have a solution for the formula in the schedule.
