### C.35.1 Manufacturing 3D Model Module

Table C.35.1-1 defines Attributes specific to models used in medical 3D manufacturing.

Table C.35.1-1. Manufacturing 3D Model Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Measurement Units Code Sequence | (0040,08EA) | 1 | Units of distance for the coordinate system for the encapsulated STL file. Only a single Item shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | DCID 7063 “Model Scale Units”.
Model Modification | (0068,7001) | 3 | Specifies whether a modification of the observed anatomy (other than mirroring) was used to create the model (e.g. simulating an expected surgical result). In the negative, the model follows the observed patient anatomy in the source data. Enumerated Values: YES NO
Model Mirroring | (0068,7002) | 3 | Specifies whether mirroring of anatomy from the other side of the patient was used to create the model. Enumerated Values: YES NO
Model Usage Code Sequence | (0068,7003) | 3 | Specifies the use for which the manufactured object is intended. Only a single Item is permitted in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | BCID 7064 “Model Usage”.
Content Description | (0070,0081) | 3 | A description of the model.
Icon Image Sequence | (0088,0200) | 3 | A preview image representing the rendered model. Only a single Item is permitted in this Sequence.
>Include Table C.7-11b “Image Pixel Macro Attributes” | See Section C.7.6.1.1.6 for further explanation.
Derivation Algorithm Sequence | (0022,1612) | 3 | Software algorithm that created the 3D model. Only a single Item shall be included in this Sequence.
>Include Table 10-19 “Algorithm Identification Macro Attributes” |
