Dear Frends!
Revit has a wonderfull solution that allows it to change door directions - a small arrows near a door instance. But IRL most doors have a door swing. This revit solution is very helpfull in the very first stages of project work. But in the end stages the door swing became an important thing -for example, if you mirrired doors, it is unable to detect a rihgt information about a door swing. I develop a solution, that analize door by its 2D representation (and find another usefull information about door).
Lets try it, it is free

Beside doors there are a more free helpfull tools for calculation rooms finish.
