Site plans and other spatial information can be useful for gaining a perspective of the dimensions of the model, and for locating important spatial features within the model domain. Although these maps may not contain any specific data used in the calculations, and the presence of a map does not influence the results of the simulation, they are useful for enhancing visualization of the model and in the decision making-process (e.g. what are the simulated results within a given property line?).
Visual MODFLOW Flex supports import and visualization of AutoCAD drawing exchange files (DXFs) for use as a vector basemap.
Note: All entities within the DXF file will be processed for import and any compatible entities will be imported into the project and displayed using the same color. As such, it may be useful to remove entities that are not relevant to the model prior to import.
To import a DXF into VMOD Flex, follow the steps below:
•Right-click in the Data Explorer and select Import Data... from the pop-up menu.
•Select Dxf from the Data Type drop down list.
•Click the [...] button and locate the source file.
•Enter a Name and a Description for the data, and click [Next] to continue
•Next, select the Coordinate System of the image file.
•Click the [Next] button to continue to the next step.
•A summary of the number of DXF entities processed and the number that will be created in Flex will be displayed
•Click the [Finish] button to finalize the import.
Note: the coordinate system of the DXF file must be consistent with the one defined in the project settings as Flex will not perform a geotransformation on entities within the DXF. You can import points, polylines, or polygons that exist within a DXF file separately.
