Parametric squares

I wanted to create design by using parameters. When I create this design, I applied these steps:

1- I opened new families file as Generic Model

2- I created my referense lines

3- I defined my parameters

4- I created my basic shapes by using extrusion tool. To fit the shapes in my references, I used align tool. (Red color shows my shape)

5- I opened new file for project. Then I uploaded my shape to the project file. 

6- Click one of the object and I changed the parameters of the object by using family type. I applied this all the object.

8- I used "visual style" tool to change the appearence of the design. This images shows the 3D of my design.

9- I changed the material of the project. 

This is the final view of the project:
