Global axis systems in CAD design and optical design are usually different. While a vehicle's reference axes are aligned along or across the road, the lighting reference is always a local optical axis system. In LucidShape, you can easily switch between global reference systems in just two steps!
First, please be sure to store an existing axis system, or create a new axis system to memorize your original global system (create axis system). Second, use the “Set Global Axis” option on the Geometry menu to turn the axis system of your choice into the new global reference. This way, you can import any design from any reference, set the global axis to be the optical one, and finish your lighting development task as effectively as possible with all of the dependent relations being in alignment for your tool and design rules. Once this is done, you can then export your solution back to the CAD system in its native reference system again, using the "Set Global Axis" option.
