In computer-aided design (CAD) software like Rhino, the projection plane is a fundamental concept that determines how 3D objects are displayed on a 2D screen. It defines the orientation and position of the virtual camera relative to the model, allowing users to view and interact with their designs from various perspectives.
Setting the projection plane is crucial for several reasons. Firstly, it enables users to visualize their models accurately, ensuring that they have a clear understanding of their geometry and proportions. Secondly, it allows for precise measurements and dimensioning, as the projection plane serves as a reference for determining distances and angles within the model. Moreover, setting the projection plane is essential for creating technical drawings, as it determines the orientation of the views that will be exported to 2D layouts.
