### CoordinateSystemOptions
Fields
| Type | Name | Default | Description |
| -------------- | ------------------------ | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| orientation | studio.OrientationSelect | | Defines how the imported model's orientation (or coordinate system) is evaluated, to be correctly converted to match Pixyz Studio's own system (right-handed, Y is the Up-axis).\
If 'Automatic Orientation' is enabled, Pixyz Studio performs an automatic conversion.\
Use 'Manual Orientation' if the automatic detection does not work: fill in the characteristics about the imported file's coordinate system to help Studio convert the file correctly. |
| scale | studio.ScaleSelect | | Defines how the imported models' scale and units are evaluated, to be correctly converted to match Pixyz Studio's own units (mm).\
If 'Automatic scale' is enabled, Pixyz Studio performs an automatic units conversion, and applies a corrective scale if required.\
Use 'Manual Scale' if the automatic detection does not work: for example set a 0.1 scale value to convert a file in centimeters to millimeters. |
| snapToGround | Boolean | False | Automatically snaps/moves the imported model onto the ground of the scene (on the grid).\
This parameter changes the imported model's original position relatively to the origin, in the upward direction (Y-axis).\
Do not use to keep model's original absolute position. |
| centerToOrigin | Boolean | False | Automatically centers the imported model to the origin of the scene.\
This parameter changes the imported model's original position relatively to the origin, in all directions.\
Do not use to keep model's original absolute position. |

### ImportOptions
Fields
| Type | Name | Default | Description |
| ---------------------- | ------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| orientFaces | Boolean | False | If enabled, Pixyz Studio tries to orient model's faces (normals) consistently so they face the proper direction.\
Do not use if the original's model faces orientation is already correct, as the process may destroy it.\
If the model is not 100% properly oriented after import, use the functions from the 'Mesh' menu to fix faces orientation. |
| preserveOriginalUVs | Boolean | True | UVs applied to a mesh are used to properly display materials using texture maps.\
If 'Preserve Original UVs' is enabled, Pixyz Studio imports the UVs included in the imported model (on any channel), and creates UVs on meshes that do not have any UVs (by a 400x400mm BoundingBox projection on channel 0).\
If the parameter is disabled, all UVs (from any channel) are destroyed and new ones are created (same BoundingBox projection). |
| removeDuplicatedMeshes | Boolean | True | Use to remove duplicated/superimposed meshes (= parts).\
Do not use if the imported model includes different configurations of the same model, resulting in intentionnaly duplicated parts. |
