Preview Image of Building Model
You can create a preview image of the building model (MODEL.vxm) in the local archive to the building folder. The image is a jpg file. The preview image is displayed in the building browser in front of the building id.

You can create the preview image when closing or saving the building.
- Create a preview image when closing the building. After you have made changes to the building since the last save and you close the building, a preview image is generated when you select Save. When saving a building using File > Save or pressing Ctrl+S, the preview image is not updated. This speeds up saving the building, especially in network server installations. The functionality is enabled as a default.
- Create a preview image when saving the building. You can enable the preview image creation also when saving the building by editing the value of the keyword save_preview_bmp in the system settings. By default, save_preview_bmp = 1. In this case, the preview image is created only when closing the building. Add to the value:
- +2 - The preview image is created when you save the building by selecting File > Save.
- +4 - The preview image is created when you save the building by pressing Ctrl+S.
The preview image is generated from the view in the model window at the time of closing or saving.
By default, the preview image is not perspective. If you want a perspective preview image, change the keyword thumbnail_perspective to 1 in the system settings (default is 0):
thumbnail_perspective= 1
Note: The keyword affects all preview images that are generated, including thumbnails of components in the component library.
You can view the preview images in Windows Explorer as follows:
- Select either the shared/projects folder or an individual building folder under it in Windows Explorer.
- Select the option to display the thumbnails of the files for viewing in Windows Explorer.
Note: A preview image of a building in Vertex Sync is generated each time the building is synchronized. The preview image is generated from the view in the model window at the time of synchronization.
