If you have legacy drawings created in previous versions, and they contain area objects, these areas will automatically be converted to spaces when you open the drawing with the current software. The following table maps area properties to space properties.
| Area property | Space property | Value/Default value |
|---|---|---|
| Name | Name | Existing value |
| Description | Description | Existing value |
| Layer | Layer | Existing layer (A-Area-G) |
| Style | Style | Area style is converted to space style. Properties are matched where possible; new properties have default values. |
| Calculation modifiers | Calculation modifiers | Existing modifiers Note: By default, converted calculation modifiers are applied only to the base area and base perimeter of the space.
|
| N/A | Geometry | 2D |
| Base Area | Base Area | Existing value |
| Calculated Area | Calculated Area | Existing value |
| Base Perimeter | Base Perimeter | Existing value |
| Calculated Perimeter | Calculated perimeter | Existing value |
| Rotation | Rotation | Existing value |
| Elevation | Elevation | Existing value |
| Additional Information (Location) | Additional Information (Location) | Existing values |
| N/A | Length | Existing value |
| N/A | Width | Existing value |
If the legacy area has no override for display properties at the style level, then one will be created on the migrated space to mimic the drawing default display properties of the legacy areas. This is intended to preserve visual fidelity for legacy areas that do not have display property overrides. Existing style or object display property overrides on legacy areas will carry forward to the migrated spaces.
Previous versions of the software allowed users to create areas that self-intersect. Spaces cannot self-intersect. During migration, a self-intersecting area is converted into a self-intersecting space, and a solution tip displays, advising you to grip-edit the base boundary to remove the self-intersection.
