Requirements

Xchange A-SPEC module

Options

The following properties allow control of the export.

General	Description
Content	Displayed - If no objects are selected then only visible objects are exported. All - If no objects are selected then all objects are exported regardless of whether they are visible.
Version	Select the A-SPEC version the file should be written for.
Extended Report	Select whether a detailed report should be created during the export.
Data Format	Select the format that the data should be exported in.
Datum	Select the datum that the data should be exported on.
St_Name Attribute	Description
Layer	Select the layer on which the street name polygons are stored.
Attribute Definition	Select the attribute definition that contains the street name attribute.
Location Attribute	Description
Layer	Select the layer on which the location polygons are stored.
Attribute Definition	Select the attribute definition that contains the location name attribute.
Lot_No Attribute	Description
Layer	Select the layer on which the allotment polygons are stored.
Attribute Definition	Select the attribute definition that contains the lot number attribute.

Notes

The export supports the D-Spec, O-Spec and R-Spec components of the A-Spec standard specification.
D-Spec is the stormwater drainage component of the A-Spec standard specification.
O-Spec is the open spaces component of the A-Spec standard specification.
R-Spec is the road component of the A-Spec standard specification.
Projects containing the required layers, layer groups and attribute definitions can be created via the inbuilt A-Spec 2019 and A-Spec 2023 templates.
The A-Spec 2023 template supports the following standard versions:
- D-Spec 9.0.6.
- O-Spec 3.0.6.
- R-Spec 3.0.6.
The A-Spec 2019 template supports the following standard versions:
- D-Spec 9.0.5.
- O-Spec 3.0.5.
- R-Spec 3.0.5.
The following attributes are automatically inserted and populated during the export process:
- Length and Area are calculated from the geometry of the object.
- Easting, Northing and FSL values are determined from the vertex of the point. If the point has a default height the FSL value is populated with the default value '-9999'.
- US_Pipe_E, US_Pipe_N, US_IL, DS_Pipe_E, DS_Pipe_N, DS_IL, St_Con_E, St_Con_N, En_Con_E and En_Con_N values are determined from the vertices of the line.
- Pipe_No, DS_Pipe_No, Up_Pit_No and Dn_Pit_No values are determined from the attributes of associated objects.
- Pit Depth is determined from the finished surface level (FSL) and the outlet invert level (lowest US_IL). This attribute is only populated on export at the time it is inserted. If the lowest point accessible is not the US IL, override the computed value.
- Unique_ID and Struc_No values are generated only if there is no existing value for the attribute.
- St_Name, Location and Lot_No and AOW_ID values are determined from the polygon that contains the object and is on the layer specified in the appropriate Option.
- EPSG value is determined from the projects coordinate system.
The export validates the data and warns if any attributes are missing.
Only layers, objects and attributes that match the A-Spec definition are exported.
Layers must have the correct Intended Use set according to the matching object type in A-Spec.
Represent pits, conduit pits, or head and end walls, as a polygon or a point on the Pits, Cond_Pits or HEWalls layers. If the polygon or point symbol encloses the start or end point of a pipe or conduit, the polygon, or a rectangular polygon based upon the point symbols width, length and rotation, is exported. Any non rectangular symbol (eg circular pits or end pipes) should be represented as polygons.
If a pipe falls within the area bounded by the Pit or HEWall symbol, an additional line segment is created to the centre of the pit.
If the project Coordinate System covers areas of Western Australia (MGA zones 49-52), or is set to Perth Coastal Grid, then attributes Road_from and Road_to on layer S_CLine are exported as SLK_from and SLK_to respectively.
If any Photo_Ref attributes have the name of an image in the project, the image will be copied to the output folder.
When exporting to GeoPackage, a single file is created in the selected folder with the same name as the project.
When exporting to Esri Shape or MapInfo multiple files are created using the name of the layer.
To update a project to a later A-SPEC version, create a new project using the new A-SPEC template, then import the old project.
