| Default Area Type |
If the XPX Default Area Type is 'Inactive', data is imported as a 2D zone. For any area in the XPX file that is not an active area polygon (ie, the XPSWMM/XPStorm polygon's Default Area Type is set to 'Inactive'), the grid extent for the inactive area is subtracted from the active area polygon and the remaining area is imported as the 2D zone boundary array data in ICM. Note that if the result yields any holes, the holes are imported as ICM Polygon objects with their Category property set to Void |
|
| X,Y points | Boundary array | Applicable for data imported from LAYER in the XPX file. |
| Grid Step Size | Minimum element area | Only applicable to the XPX 2D_GRID_EXTENT layer type. The Minimum element area is imported as the value of the 'Grid Step Size' squared (F_2D_EXT_STEP2). |
Mesh Level Zone
The following fields in an XPX file are imported to a Mesh level zone type of object in an ICM SWMM network:
| XPX Field | InfoWorks ICM Data Field | Notes | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Layer Name | ID |
The format for the ID is: <Layer name>_<Layer id>_<Polyline id> |
|||||||||
| Layer ID | |||||||||||
| Polygon ID | |||||||||||
|
Vertices |
The following XPX fields are imported into the Vertices Editor in ICM.
|
Roughness Zone
The following fields in an XPX file are imported to a Roughness zone type of object in an ICM SWMM network:
| XPX Field | InfoWorks ICM Data Field | Notes |
|---|---|---|
| Layer Type | If the Layer Type in the XPX file is 2D_LANDUSE, the data is imported to a Roughness zone object in ICM. | |
| LanduseID | ID |
The format for the ID is: <Landuse ID> _ <Count> |
| Count | ||
| Area |
Calculated by ICM using the imported boundary array data. |
|
| ROUGH_VAL | Roughness (Manning's n) | Imported if Manning's roughness is set to constant in the XPX file. |
|
2D_RGH_PNIND |
Boundary array |
Applicable for data imported from DATA in the XPX file. The geometry of the porous polygon. 2D_RGH_PX and 2D_RGH_PY store all the X and Y coordinates of each point within a polygon for all the region type layers. Polygon index is the order in which the X and Y values are stored in the database. 2D_RGH_PNIND stores the number of indices per polygon while 2D_RGH_PIND stores the actual indices. |
|
2D_RGH_PX |
||
| 2D_RGH_PY | ||
| 2D_RGH_PIND | ||
| 2D_RGH_PTYPE | Imported with polygon geometry if 2D_RGH_PTYPE = 0 | |
| 2D_RGH_PVAL | ||
| X,Y points | Boundary array | Applicable if the Roughness zone is imported from the LAYER, POLYGONS and LAYER_DATA commands in the XPX file. |
Lines
Data from an XPX file is imported to the following type of Line object in an ICM SWMM network.
2D Boundary
The following fields in an XPX file are imported to a 2D Boundary type of object in an ICM SWMM network:
| XPX Field | InfoWorks ICM Data Field | Notes |
|---|---|---|
| Layer name |
Name |
The format for the name is: <Layer name>_<Layer id>_<Polyline id> |
| Layer ID | ||
| Polyline ID | ||
| X,Y points | General Line XY Data | |
| Layer type | Boundary line type |
If the XPSWMM/XPStorm Layer type is set to 2D_HEAD_BOUNDARY, the Boundary line type will be imported as Level in ICM. If the XPSWMM/XPStorm Layer type is set to 2D_FLOW_BOUNDARY, the Boundary line type will be imported as Flow in ICM. |
