Create Dimension From Edges

[shehab_fekry]

I'm trying to create dimension for columns from edges by filtering edges in x direction and y direction I'm depending on Symbol Geometry and everything works fine .. the problem is when the column is rotated the edges in x direction become in y direction .. when I use instance geometry I get the right references with their right direction but the problem is the dimension isn't created .. the references are in the reference array but the dimension isn't created 

I want to depend on Symbol Geometry as Instance Geometry changes when the column is joined with another geometry on the project also the Instance Geometry References cannot create dimensions

Is there anyway that I can transform the edges that I get from the Symbol Geometry? 

so that I can filter edges according to their real line direction in the project not their direction in the family

I have found the best solution for this scenario .. by depending or symbol geometry and then when you want to filter edges in xdirection and edges in ydirection don't order them use CreateTransformed method for the lines and pass the transform from the family instance to the method
