Layout Verification:
• Selected: 2 Rails with 2 Carriages per Rail
• Total Bearing Blocks Supporting Load: 4 Carriages
• Auditor checks if block count is sufficient to prevent overloading due to CG offsets.

3D System Visualization & Coordinate Frame Reference
Standard Coordinate System Definition (ISO / HIWIN / PMI Standard):
• **X-Axis (Lateral / Width):** Crosswise direction perpendicular to the rails (Rail Spacing axis).
• **Y-Axis (Longitudinal / Travel):** Direction of carriage motion (Stroke & Carriage Spacing axis).
• **Z-Axis (Vertical / Height):** Direction perpendicular to the mounting base (Gravity & Overturning height axis).
• **Axis Rotations ($M_x, M_y$):** Overturning moments generated by forces acting at distances ($CG_x, CG_y, CG_z$) from the guide center.
