North Angle in RHINO

would like to know the default NORTH angle in Rhino modelling, as I’m performing daylight analysis using DIVA plug-in north angle is the most prerequisite for daylight simulation.

From the Diva documentation found with a simple Google search:

Orientation

It is important that your project is oriented properly within Rhino with regards to North. In Rhino, as most other software, North is the top of the screen when viewing the model in a “Top” or “Plan” view such that the positive Y-axis is North.

Thanks for your Prompt response, Mr.David Cockey.
