Begin your project by switching to the Top orthographic view (usually NumPad 7 on standard keyboards). This removes perspective distortion, allowing you to draw or place objects based on real-world coordinates.
In geometry and robotics, an axis is a line around which an object rotates. For cameras, we generally deal with three axes: live view axis top
The "Axis" in Live View Axis Top refers specifically to the Global Vertical Axis (Gravity/Z-axis). Begin your project by switching to the Top
Before the dominance of mirrorless cameras and DSLR Live View, photographers relied on optical viewfinders (OVF). While OVFs are bright and lag-free, they suffer from coverage issues (usually 95-98%) and a lack of real-time axis data. You could not see the impact of tilt-shift adjustments or the exact vertical convergence until after you took the shot. The "Axis" in Live View Axis Top refers
Live View Axis Top solves this by providing a WYSIWYG (What You See Is What You Get) interface. When you activate the "Axis Top" overlay—usually a dual-axis electronic level superimposed over the live feed—you are given a real-time bubble level. As you tilt the camera up to capture the top of a skyscraper, the level tells you exactly when the vertical axis shifts. This allows you to compensate by adjusting the back plane of the camera to remain perfectly vertical, even if that means cropping out the foreground.
