    i need to make football playground parametric

    Hi every one, i have small playground in the project i used the one with library but it is not suitable to my project so i do a lot of adjustment to make it fit into my project. the only problem i have the goal keeper when i change length and width of playground the goalkeeper become large as well so i need control on this goal keeper when changing length and width of goal keeper as well as make the extrusion of lines that divide the playground not become distorted . can anyone of revit gurus help me on this ?
    i need to parametrize this playground so i can use it in any size of projects i want.

    This is its own family, correct?

    If so, then create parameters that drive the size of each element individually.

      No it is one family , there is no nested family.

        This reminds me of an amusing (I had to laugh) incident when someone scaled a .dwg block of a football pitch - used it - and the penalty spot ended up all of 2m away from the goal line! :banghead:

        Firstly, you need to associate (and limit) certain parameters in your family. I've not opened it up - but I imagine from your description, you've only "length" and "width" to control - which is absolutely fine, but if you're penalty box, centre circle etc, aren't "tied" to those dims (and FIFA guidance) you'll experience the "buckling" of the family.

        First consider (simple) relationships along the lines of :
        [Length = 100m]
        [Width = 75m]
        [Centre_Circle_Radius = Length/5]
        [Penalty_Area_Width= Width/3]

        then you'll be able to later do "IF" statements, that conform to the true rules...

            A football (soccer) field is one of a few things which is not worth making parametric, at least not when you need it for a playground or the like. Standard (Fifa) fields have strict measures on everything but the length and the width, and as already pointed out, the proportions won't fit a field or a playground. Best advice... Just create a copy of the family you have, change the measures to fit your playground, and call it a day.

              It would be nice to be able to change the field if my national team was playing against Brazil; I could make their goal as wide as possible, as in Ahmed's image, very easy to score! Oh, but I need another parameter to make our own goal as narrow as possible.

                Just use a Yes/No parameter on your own goals visibility, and keep it turned of during the entire game

                  Remember in your thread from yesterday about Doric columns where you said:

                  This thread is exactly why it's not always better to start with an existing family. It may seem simple to go into a family and "just" change one parameter, or delete some seemingly simple thing. But, before you know it, something else moves wrong, or scales, or fails for scale.
                  Many, many, many things in families depend on other relationships, and if you're not the person who made the family, you won't know what relies on which parameter, alignment, or locked dimension. You frequently end up spending a LOT more time trying to figure out how someone made a family that it would have taken you to just build it yourself from scratch.

                    Klaus that is what actually what i am do when i become in hurry in my projects
                    @Alfredo , well you know Brazil is strong team they will not possibly let you score anything easily because they are attacking always which will result a defending state alwayes which why i am agree with you that it should be narrow.
