6.0 Object Functionality
This section of the standard discusses the requirements for improving the functionality and performance of BIM objects so as not to detrimentally affect the performance of a model into which they may be placed.
6.3 Visibility/Views
| | 6.3 Visibility/Views
This sub-section of the standard discusses the requirements for the visibility of objects and their display views. BIM authoring systems control object viewing in different ways, such as layers and subcategories, these need to managed to avoid a proliferation of views within models. |

| 6.3.1 | Thumbnails and previews |
| | Thumbnail previews shall be set to a clear, appropriate and consistent view orientation and an appropriate size and resolution.
All reference items and dimensions shall not be visible in these images. |
| | |
| 6.3.2 | Object resolution |
| | Provision for varying object resolution when viewing the object at different scales shall be provided and the graphical information displayed shall be controlled.
Three scales of resolution should be sufficient and shall be provided for each object as follows: - Coarse: Typically used for low detail, low fidelity views, generally at a scale above 1:100. The geometry visible shall only be indicative of the physical element and can include symbolic 2D line-work
- Medium: Typically used for views at scales of 1:20 to 1:100. The geometry visible shall be sufficient to serve the purpose of representing the physical element
- Fine: Typically used for highly detailed views, usually at scales of 1:1 to 1:20. The geometry visible can reflect the detailed geometry of the physical element.
