I have been developing some tool to make a work-flow easier and recently I have got one issue.
In left pic, I placed the family instance on work plane which is perpendicular to world X,Y.
But new request i got recently is it should be perpendicular to a point which is dividing an alignment like right pic.
In my case, I could not use work plane (reference plane) because it must be perpendicular to a point.
I have done some research. however i could not find good solution.
Do you guys have an any idea?
