A. DrawLine
This button is used for creating polylines (e.g., streams, injection trenches, etc.).B. Line from a txt file
This option enables uploading a .txt file with the coordinates of polylines (line features) to be added to model. Note that this imports ONLY the feature geometries (no conceptual attributes are assigned during import, but can be assigned by editing individual lines after import).NOTE: Importing very large datasets (many polylines and/or many vertices) into the Maps Display and Working Area may significantly slow down the modeling page response time. Use the Hide/Show lines button (see below) to avoid this issue once the data have been imported. The following describes the file format (line-by-line text inputs). Each step represents the expected input (left) and an example of text input.
- Projection System file contents and Feature name(s)
- Units:
- Number of features (individual lines) contained in the file
- Number of vertices in each feature
- Coordinate for 1st vertex, for 1st feature
- Coordinate for 2nd vertex, 1st feature

Enter 'PCS:', then copy and paste the contents of the prj. file associated with the feature;
then enter 'ORG:' followed by the x- and y-coordinates of the (lower-leftmost vertex), seperated with ',';
then enter 'Names:' followed by the name/ID of each line feature. Seperate each feature with '|'.
| Lat-Lon |
Enter 'Lat-Lon' for coordinates entered in latitude-longitude format, or enter 'Meters' or 'Feet' if the coordinates are measured distances relative to the projection system origin.

Starting with row 5, all remaining rows represent a single vertex coordinate. The coordinates for a single feature are "grouped together" (one row after another) until moving on to the next feature.
C. Lines from a shapefile
This option allows importing geospatial vector data stored as a shapefile as line features in a IGW-NET model - both feature geometries and (if desired) conceptual attributes (e.g., all line features assigned as a constant head boundary condition).NOTE: Importing very large datasets (many polylines and/or many vertices) into the Maps Display and Working Area may significantly slow down the modeling page response time. Use the Hide/Show lines button (see below) to avoid this issue once the data have been imported.
D. Line from DataNET
This button initiates the process to transfer a polyline (WFS) feature(s) from M4W DataNET into the IGW-NET environment as a line feature(s).If a linked DataNET page is not already opened, clicking this button the first time will open a new DataNET page inside the browser. Login using your MAGNET account, select the layer of interest from the Data TreeView, draw a selection box around the specific polyline feature of interest, and use Data Transfer to send the polyline into IGW-NET (Data Manipulation > Transfer > select WFS Service > Send).
If the selection box includes two or more polyline features, all of the features will be transferred into IGW-NET and available for import (the user decides which ones to include during import).
E. Paste
Select this option to paste the last copied polyline (line) feature to the current model layer. Access a polyline's attribute window with the LineAttr option to copy a line feature.F. Hide Lines
This option temporarily removes all line features from the Maps Display and Working Area to 'declutter' the work environment. (NOTE: the conceptual line features are still present/active in the model if this option is used.)Add the line features back to the display by selecting 'Show Lines' (in the same location where 'Hide Lines' is found).
