Hi
I want to export an object in non sequential mode using 'CAD files'. I want to create a step file of the object. How is the 0,0 point determined? I want to put the 0,0 point at a specific location relatve to the object so when I import it, I know exactly where it is placed.
thanks

Hi John,
I have updated the name if the forum thread for you!
With respect to your question: The (0,0) location in your STEP file will match the global coordinate origin of the Non-Sequential system. A quick way to see that location in OpticStudio is to place a Source Ray at location (0,0,0) with Ref Object = 0. This means that the source's axis will be aligned perfectly with the global reference which will then indicate the global (0,0) location.
Here is an example of what I mean. In this file, I have two Rectangular Volume Objects and one Source Ray. Objects 1 and 2 are currently aligned with the global origin:
When I export these objects as a STEP file, the global coordinates in SolidWorks will match the location of the Source Ray:
Even when I export Object 4 on its own, the global coordinates remain the same:
Let me know if you have any other questions about this!
Best,
Allie

+2Oh one more quick note:
In my OpticStudio file, you will see that the second Rectangular Volume is +2 in the Y-direction from the origin, yet in the SolidWorks file, it looks like it is +1. That is because the local axis for the Rectangular Volume is located in the center of the left face:
So the positions in OpticStudio are always updating the location of the object's local axis with respect to the Ref Object.
