Project Properties
The Properties page displays information about the current project, including metadata, content counts, element statistics, and resource usage. Use this page to document project provenance, verify content before sharing, and monitor resource consumption.
Page Sections
The Properties page presents information in organized sections:
| Section | Content |
|---|---|
| General | Project name, authorship, timestamps, and file information |
| Content | Counts of objects by type (volumes, masks, surfaces, etc.) |
| Elements | Totals for geometric elements (points, triangles, voxels) |
| Statistics | Memory usage and aggregate object counts |
General Information
Basic project identification and file details:
| Field | Description |
|---|---|
| Project name | Filename of the project |
| Title | User-defined project title |
| Subject | Subject or topic of the project |
| Tags | Comma-separated keywords for categorization |
| Comments | Free-text notes about the project |
| Author | Creator of the project |
| Last modified by | Who last edited the project |
| Manager | Project manager or supervisor |
| Company | Organization or institution |
| Revision number | Version or revision number |
| Created | When the project was first saved |
| Last modified | When it was most recently saved |
| Last accessed | When it was last opened |
| Total editing time | Accumulated time the project has been open for editing |
| File size | Size of the project file on disk |
Content Counts
Summary of objects in the project, showing both total and currently visible counts:
| Object Type | Description |
|---|---|
| Volumes | 3D image/volume objects |
| Masks | Segmentation mask objects |
| Surfaces | Triangle mesh surface objects |
| Volume meshes | Tetrahedral and hexahedral mesh objects |
| Measurements | Distance, angle, and other measurement annotations |
| Primitives | Geometric primitives such as spheres, cuboids, and planes |
| Analysis | Analysis result objects |
The Total column shows all objects of each type; the Visible column shows only those currently visible in the views.
Element Statistics
Aggregate counts of geometric elements across all objects:
| Element | Description |
|---|---|
| Points count | Total vertex count across all surfaces |
| Triangles count | Total triangle count across all surfaces |
| Volume elements count | Total cell count in volume meshes |
| Voxels count | Total voxel count in volumes and masks |
These statistics help assess project complexity and anticipate processing requirements.
Memory Usage
The Statistics section reports Total objects, Visible objects, and Memory usage, the last being the approximate footprint of the project's loaded data. Watch it when:
- Working with large datasets
- Combining multiple volumes or high-resolution surfaces
- Experiencing performance issues
If memory usage approaches your system's available RAM, consider closing unnecessary objects, reducing resolution, or working with data subsets.
Advanced Properties
The Advanced Properties button opens a dialog for detailed metadata editing across multiple tabs.
General Tab
Edit the following metadata fields:
| Field | Description |
|---|---|
| Title | Descriptive title for the project |
| Subject | Subject or topic |
| Author | Project creator |
| Manager | Supervising individual |
| Company | Organization |
| Tags | Keywords (comma-separated) |
| Last modified by | Who last edited the project |
| Comments | Extended notes |
Summary Tab
Read-only, in two groups:
- Project Information: Project name and File size
- Content: object counts per type, each with a Total and a Visible column
Statistics Tab
Read-only, in four groups:
- Project Statistics: Created, Last modified, Last accessed, Last modified by, Revision number, Total editing time
- Object Statistics: Total objects and Visible objects
- Element Statistics: Points count, Triangles count, Volume elements count, Voxels count, each with a Total and a Visible column
- Memory usage: Estimated memory usage
Workflow: Editing Properties
- Navigate to File → Properties
- Click Advanced Properties...
- Edit fields in the General tab
- Review information in Summary and Statistics tabs
- Click OK to save changes
- Use File → Save to persist changes to the project file
Changes made in Advanced Properties update the backstage Properties page immediately. However, you must save the project for changes to persist.
Use Cases
Documenting Project Provenance
Before sharing or archiving a project:
- Open Advanced Properties
- Fill in Author, Company, and Title
- Add descriptive Tags and Comments
- Set the Revision number if versioning
- Save the project
Validating Content Before Export
Before exporting or delivering:
- Review Content counts to verify expected objects are present
- Check Visible counts if export respects visibility
- Verify Element statistics match expectations (e.g., triangle counts for surfaces)
Monitoring Resource Usage
When working with large datasets:
- Check Memory Usage to assess current load
- Review Voxels and Triangles counts for large objects
- Close or hide unnecessary objects if resources are constrained
Workflow: Reviewing Project Before Sharing
- Open File → Properties
- Verify General information is appropriate for sharing
- Check Content counts match expected data
- Open Advanced Properties to review/update metadata
- Remove or update any sensitive information in Comments
- Save the project
- Proceed with export or file sharing
