To address the benefits of the orientation of a building in energy aspects, the first step may be a solar study. In relation with that, it is better to have an understanding of a few basic terms What is day light saving time, the difference between true south and magnetic south, magnetic declination, clock time and solar time, azimuth angles, insolation etc.
As we know, Revit has three points which are used when we link external drawings to Revit. Revit origin, Project Base point and Survey Point. We had a requirement to get the Revit origin for some purpose associated with drafting views. For that we used a macro using C#. We are using this macro now for that purpose. We have created a circle using a macro at origin to get the origin point.
