In this instance the Solidworks model was brought into Inventor as before. This time it is assumed that the component is very complex. It may be that the components is sourced form a manufacturer. Imagine the file size of an air conditioner if every nut and bolt is included. The tool that is included in Inventor is called Shrink-Wrap. <Environments><BIM Exchange><Shrinkwrap Substitute>
Hovering over the icon displays some help on the command.
A new derived substitute part is created.
Note the Assembly Shrinkwrap Options. They are explained in more detail in the help http://help.autodesk.com/view/INVNTOR/2017/ENU/?guid=GUID-AA42BC7E-E2FC-4E73-8EE1-FD3D5E6AC536.
For each of the styles, and for a partial explode and full explode, the following data is recoded.
| ADSK Export Type | Explode | Revit Geometry | Materials Ported? | Disk Size |
| No Edit | Partial | Yes | Yes | 752 |
| No Edit | Full | Yes | No | 1240 |
| Single solid body merging out seams between planar faces | Partial | Yes | Yes | 556 |
| Single solid body merging out seams between planar faces | Full | No | No | 224 |
| Solid body keep seams between planar faces | Partial | Yes | Yes | 560 |
| Solid body keep seams between planar faces | Full | No | No | 224 |
| Maintain each solid as a solid body | Partial | Yes | Yes | 544 |
| Maintain each solid as a solid body | Full | Yes | No | 832 |
| Single composite feature | Partial | Yes | Yes | 540 |
| Single composite feature | Full | Yes | No | 832 |
Every model that is processed in this way will be different. The conclusions are that a partial explode takes up less space than a full explode, and that a simplification of the model results in significant file size reduction. Even so, it is probably worth thinking about creating a representative geometry in Revit (of much smaller file size), especially if visualization is not too important.
