Specify the precision <0-99>. Type Y to Convert Lines, Arcs and Splines to polylines. Note: The PEDIT command does not allow splines to be selected beforehand. To convert multiple splines at the same time, use the PEDIT command: At the command line in AutoCAD, type PEDIT.

To estimate or improve the accuracy of each node's. Process can be done using GPSmapedit software. Knowing exactly where the boundary lines are is important for many different activities.

With the name highlighted, select the Polygon tool from the object creation toolbar. Check the visible box and make sure the layer is not locked.Also sometimes gpsmapedit complains about too short distance (under 2.3m) of routing nodes, but I think these are false positives, as I think this problem.i took my lebanon map from garmin on windows mobile (.img) i then edited using GPSMapEdit and made a polish format (.mp) using the same program (yes, you can do that), i then use GPSMapEdit to make the Navitel 5.5 format (.nm2), then use the converter from Fenyo to make the (.nm2) and the index file become one (.nm3) file, which worked everywhere. On the Layer Control Panel, select the Grid Extents layer. It almost works but there's a region of the map on a segment of the merge line that doesn't render correctly and sometimes crashes BaseCamp when I. I'm trying to solve the problem by using two source map files then merging them together into a single mapset.

Click once to add a vertex. Draw a polygon that defines the extent of the 2D domain by clicking and dragging the mouse. Generate Routing Graph Using coinciding nodes of Polylines.

Then edit the polygon by adding and adjusting the vertices. One polygon drawing technique is to “rough in” the area with a few vertices. Under the Extent Boundary section, set the Line Size to 3 and change the Extent Cells Line Color to Red. You can edit the display properties of the 2D domain and 2D Grids by right-clicking the 2D Grid layer and accessing the Properties option. When the polygon is completed, a rectangular grid will be displayed.

Hold the left button down, drag the vertex to a new location and release. It will appear as a four-arrowed cross. Move the cursor over a vertex.

Move to another location on the boundary to add a new vertex. The vertex may be moved by dragging it to the new location. Click once to add a vertex. The cursor will appear as a box with arrows moving inward. Move the cursor over the polygon boundary. A red dot will appear next to the cursor.

Right-click and select Delete Vertex from the menu. It will appear as a four-arrowed cross. Move the cursor over a vertex.

Type in “Grass” and click the Add button. In the left panel, select 2D Landuse from Data Base Type. To access the landuse categories, they must first be entered in the Global Database. On the Configuration menu, select Global Data. Select the box for Show 2D Cell Center Elevation. In the Line Properties section, set the Grid Step Size to 15 ft. On the Layers Control Panel, select the Grid Extents layer and right-click.

Select Grass as the Default Landuse Category. Select the box next to 2D Model Active. To setup the 2D Job Control on the Configuration menu, select Job Control > 2D Model Settings. Set the 2D Model Job Control Parameters: This is a useful tool for entering the roughness of natural streams which are essentially variable with the depth of flow.Click OK twice to return to the network view. If you click the Variable roughness radio button, you can enter the Depth vs Roughness values for the database.

To enhance viewing, adjust the display settings. Construct a polygon that runs along the top of each bank from Node1 to Node5. Because this area lies within the 2D Area Extent, it must be defined as an Inactive 2D area. The area that is modeled with 1D cross sections excluded from the 2D model. Define the 1D open channel extents. In this example, you only need to alter the settings on the General branch of the tree.

Define the 1D/2D interface: The boundary between the 1D and 2D layers is represented as a polyline. Construct the polygon using the procedures described in Step 2.Alternatively, to save time, you can import the inactive 2D area from the GIS (Shape or Mapinfo) files:To do this, right-click the Inactive 2D Area layer and select Import from GIS File option.Browse for the file 2D_Inactive_Area.shp, select Open, and Import. With the layer name highlighted, select the Polygon tool from the object creation toolbar. Select the visible box and make sure that this new layer is not locked. On the Layer Control Panel, right-click the 2D Model layer and select Add New Layer > Inactive Areas.

Construct two polylines along the border between the Inactive 2D area and the Active 2D Grid along the left and right banks. Make sure that Snap Mode button in the top toolbar is on. With the layer name highlighted, select the Polyline tool from the object creation toolbar. Select the visible box and make sure that the layer is not locked. On the Layers Control Panel, select Add New Layer > 1D/2D Interfaces.

On the Layers Control Panel, select Add New Layer from the 2D Model then add the 1D/2D Connections layer. Add this layer and use the default name. The 1D and 2D areas of the model are linked to polylines from 1D nodes to vertices of the 1D/2D interface.

Repeat for the remaining nodes. Click OK to return to the network view. Select the box next to Link River Crest to 2D. Double-click a node to open the Node Data Dialog. Make sure that there is a connection for each end of the 1D/2D interface. Construct a polyline from each node to the nearest vertex of the 1D/2D interface.

Double-click the 2D Head Boundaries to open the dialog. Construct a polyline along the edge of the Active Areas. Locate the lowest point along the lowest edge of the Active Area. Select the Polyline tool from the object creation toolbar. On the Layers Control Panel, select Add New Layer from the 2D Model then add the Head Boundaries layer.

In the Hydraulics Job Control dialog, click the Routing Control button. Increase the inflow hydrograph defined in Node1. Hence you do not need to define another 2D flow boundary.

Several files will be created in the local directory. Solve the model. On the Analyze menu, select Solve or click the Solve tool. This will increase the hydrograph defined in Node 1 by a factor of 20.

The interface will automatically load the diagnostic file ( 1D-2D_Flooding01_messages.mif) to the diagnostic layer. Pre-processing may identify errors in the 1D/2D model that prevent the model from solving. At the end of simulation the text output and binary results files will be created. The engine is faster if the Don’t Show Model Status box is checked. The calculation may be paused and then continued. The XPS 1D/2D Simulation dialog displays the status of various parameters during the calculation.

Mif file and will be displayed in the network view. Any error messages that occur are listed in the. Reduce the number of messages that are displayed to facilitate viewing. Mif file and select properties. If there are too many messages, right-click the.

Select the 2D Vectors, 2D Maps and Legends boxes to display these layers.Right-click the 2D Vectors Max Velocity layer and select Properties from the menu.In the Arrow Head section, set the size to Fixed, Length to 3, and Width to 2.In the Total Length section, set the Fixed Size and enter 10 as the scale factor. Animations of results can be displayed as vectors (flows or velocity) and as maps (water depth, water elevation, or hazard). The display of 2D results is managed in the Results layer panel. Set the results properties. A guide to interpreting and resolving errors is provided in the Appendix of this tutorial.

Click the Play button to display the animation of velocity and water depth during the simulation period.
