To make an axis 3D model look correct, align it with your project’s coordinate system and use consistent 1:1:1 scaling across all axes.
This ensures the X, Y, and Z axes stay perpendicular and match logical dimensions (e.g., X for width, Y for height)—preventing stretching or distortion. In tools like Blender or AutoCAD, use grid snapping to keep axes aligned and measurement tools to verify scaling.
If your axis looks skewed, reset its scale to 1:1:1 in the transform menu and confirm the coordinate system (right-handed vs. left-handed) matches your project’s needs.
