The goal is to create a clear cover that will be used to cover a courtyard, where there is a tree. The roof must adapt to the position of the tree. Since we do not know exactly where the tree will be placed. We must be able to move the tree and, noting that the shape of the roof changes accordingly.
Steps:
1. It begins with the creation of two points in space
2. You create a line by points (the starting point - a point / End point - point 2)
3. You create a second line, with initial point 2, as long as the first line, and Z direction
4. You create a relationship between the first and second line, where the second line has a length inversely proportional to the length of the first line
5. It makes a translated copy of section 2 according to a set that defines an XY grid, which leads to a translation of the first lines, each of which starts at the point 1 and 2 arrive at the grid points, and second lines, each of which starts from the grid points 2, is directed vertically, and has a inversely proportional to the length of the first line associated with it.
6. Is defined by a surface poles, and poles are defined as the end points of lines 2
At this point you can see that the position of point 1 would result in the change of the surface is created depending on its position in relation to the grid.
