Change Alignment Curve Label style using Civil 3D .NET API

By Partha Sarkar

Do you want to change the Label style of an Alignment curve element using Civil 3D .NET AP ? Here is the C# code snippet which demonstrates how to do this :

public void ChangeAlignmentCurveLblStyle()

{

 

    Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;

    PromptEntityOptions pops = new PromptEntityOptions("Select Alignment Curve Label : ");

    pops.AllowNone = true;

    PromptEntityResult pres = ed.GetEntity(pops);

    if (pres.Status != PromptStatus.OK)

        return;

    using (Transaction tr = HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())

    {

        try

        {

            AlignmentCurveLabel alignCurveLbl = (AlignmentCurveLabel)tr.GetObject(pres.ObjectId, OpenMode.ForWrite);

            ed.WriteMessage("\nAlignment Curve Label Style Name (before Change) : " + alignCurveLbl.StyleName.ToString());

            // The following Style Name is specific to Tutorial DWG file - "Labels-6a.dwg"

            alignCurveLbl.StyleName = "Design Data";

            ed.WriteMessage("\nAlignment Curve Label Style Name (after Change) : " + alignCurveLbl.StyleName.ToString());

            tr.Commit();

        }

        catch (System.Exception e)

        {

            System.Windows.Forms.MessageBox.Show(e.Message);

        }

 

    }

}

After executing the command in AutoCAD Civil 3D you will see a result similar to the screenshot below – 

Change the selection color in MapGuide Ajax viewer and Fusion viewer

By Daniel Du

As you know, if a feature is selected, it will be highlighted as blue by default, but is it possible to change to other color for selection? It is possible to change the selection color when plotting as well? Yes, it is. In this article, I would like to introduce how to do that.

To change the selection color of select features in Ajax viewer, you can open the ajaxmappane.temp file in text editor, change the value to your favorite color. The value is 0xRRGGBBaa where each is a hex value from 0-255 representing your RGB and transparency (alpha) values. Currently the alpha value does not have any impact as either FF or 00, it is hardcoded in source code.

C:\Program Files\Autodesk\MapGuideEnterprise2011\WebServerExtensions\www\viewerfiles\ajaxmappane.templ

around line 335:

//var selectionColor = '0x0000FFFF'; // Blue
var selectionColor = '0xFF5300FF';

If you want to change the selection color of print as well, you will have to modify printablepage.templ file. Please pay attention to the words highlighted.

C:\Program Files\Autodesk\MapGuideEnterprise2011\WebServerExtensions\www\viewerfiles\printablepage.templ

Line 72:

if(requester.responseXML)
{
    if(ValidateMapResponse(
         requester.responseXML.documentElement))
        //document.getElementById("mapImage").src = 
        //webAgent + "?OPERATION=GETMAPIMAGE
        //&FORMAT=PNG
        //&VERSION=1.0.0&SELECTION=
        //&MAPNAME=" + encodeURIComponent(mapName) 
        //+ "&SESSION=" + sessionId 
        //+ "&CLIENTAGENT=" + encodeURIComponent(clientAgent) ;

        document.getElementById("mapImage").src = 
         webAgent 
         + "OPERATION=GETDYNAMICMAPOVERLAYIMAGE
         &FORMAT=PNG
         &VERSION=2.0.0
         &SELECTION=
         &MAPNAME=" + encodeURIComponent(mapName) 
        + "&SESSION=" + sessionId 
        + "&CLIENTAGENT=" 
        + encodeURIComponent(clientAgent) +
        "&BEHAVIOR=7&SELECTIONCOLOR=FF5300FF" ;
}

With this modification, we use GETDYNAMICMAPOVERLAYIMAGE as operation and pass the BEHAVIOR and SELECTIONCOLOR as additional parameters. You may be curious about the BEHAVIOR parameter. MapGuideRfc38( http://trac.osgeo.org/mapguide/wiki/MapGuideRfc38 ) gives us an explanation. In old release, MapGuide rendered the selection and the overlay image as a single image. This required all untiled layers to be redrawn whenever the selection is changed. To make it more efficient, an improvement is implemented to add the parameter BEHAVIOR to the existing GETDYNAMICMAPOVERLAYIMAGE and increase the VERSION to 2.0.0. BEHAVIOR is a bitmask with the following values:

RenderSelection = 1 // Renders the selected feature(s)
RenderLayers = 2    // Renders the features on the map
KeepSelection = 4   // Renders the selected feature(s) 
          //even if they are outside the current scale

With this change, the color of selected features is also changed while plotting.

If you are using Flexible Web Layout (Fusion Viewer), you can change the selection color from MapGuide Studio. Open the flexible web layout in MapGuide Studio, and switch to Map tab. By clicking “Edit Map Groups” button, you will get the xml configuration of map groups as below, and you can change the value of <SelectionColor> to other color value:

<?xml version="1.0" encoding="utf-8"?>
<MapSet xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance 
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <MapGroupType id="Sheboygan">
    <Map>
      <Type>MapGuide</Type>
      <SingleTile>true</SingleTile>
      <Extension>
        <ResourceId>
          Library://Samples/Sheboygan/Maps/Sheboygan.MapDefinition
        </ResourceId>
        <SelectionAsOverlay>true</SelectionAsOverlay>
        <SelectionColor>0xFF5300FF </SelectionColor>
      </Extension>
    </Map>
    <Extension />
  </MapGroupType>
</MapSet>

Here is the screen-shot after modification:

To change the selection color of printing in Fusion viewer, you have to modify the source code of printablepage.templ. Here is the code snippet:

C:\Program Files\Autodesk\MapGuideEnterprise2011\WebServerExtensions\www\fusion\widgets\Print\printablepage.templ

Line 53:

        //var imgReq = webAgent + "?OPERATION=GETMAPIMAGE
        //&VERSION=1.0.0&FORMAT=PNG&LOCALE="+locale
        //+"&MAPNAME=" + encodeURIComponent(mapName) 
        //+ "&SESSION=" + sessionId + "&SETDISPLAYWIDTH=" 
        //+ mapWidth + "&SETDISPLAYHEIGHT=" + mapHeight 
        //+ "&SETDISPLAYDPI=" + dpi + "&SETVIEWSCALE=" 
        //+ scale + "&SETVIEWCENTERX=" + centerX 
        //+ "&SETVIEWCENTERY=" + centerY + "&SEQ=" 
        //+ Math.random() + "&CLIENTAGENT=" 
        //+ encodeURIComponent(clientAgent);

        var imgReq = webAgent 
        + OPERATION=GETDYNAMICMAPOVERLAYIMAGE
        &VERSION=2.0.0
        &FORMAT=PNG&LOCALE="+locale
        +"&MAPNAME=" + encodeURIComponent(mapName) 
        + "&SESSION=" + sessionId 
        + "&SETDISPLAYWIDTH=" 
        + mapWidth + "&SETDISPLAYHEIHT=" + mapHeight
        + "&SETDISPLAYDPI=" + dpi + "&SETVIEWSCALE=" 
        + scale + "&SETVIEWCENTERX=" + centerX 
        + "&SETVIEWCENTERY=" + centerY + "&SEQ=" 
        + Math.random() + "&CLIENTAGENT=" 
        + encodeURIComponent(clientAgent) 
        + "&BEHAVIOR=7&SELECTIONCOLOR=0xFF5300FF";

And here is the screen-shot after modification:

OK, with that you can change the selection color to your favorite ones for both Ajax viewer and fusion viewer when viewing and printing. Enjoy !

 

 

Programmatically Attach and Detach DWG files in AutoCAD Map 3D

By Partha Sarkar

Are you looking for a way to attach or detach dwg files in AutoCAD Map 3D using .NET API?

If the answer is ‘YES’, you are at the right place. DrawingSet class in Map 3D .NET API has the necessary API function to attach a DWG file using DrawingSet.AttachDrawing() as well as detach a DWG file using DrawingSet.DetachDrawing(). To access the DrawingSet object you need to make a reference to the ManagedMapApi assembly located in the Map 3D installation folder (For Map 3D 2012 release its here -  C:\Program Files\Autodesk\AutoCAD Map 3D 2012\ManagedMapApi.dll)

Here is the code snippet which demonstrates the Attach and Detach DWG files using Map 3D .NET API functions –

 public void AttachDWG()

 {

    MapApplication mapApp = HostMapApplicationServices.Application;

    ProjectModel activeProject = mapApp.ActiveProject;

    ProjectCollection progList = mapApp.Projects;

    DrawingSet dwgSet = activeProject.DrawingSet;

 

    // String to indicate the DWG file path

    string dwgStr = @"C:\Data_set\DWGs_Map\Street_Centerlines.dwg";

    try

    {

        AttachedDrawing dwgAttached = dwgSet.AttachDrawing(dwgStr);

        dwgAttached.Preview();

 

    }

    catch (MapException ex)

    {

        ed.WriteMessage(ex.Message);

    }

 }

 

 

 public void DetachDWG()

 {

    MapApplication mapApp = HostMapApplicationServices.Application;

    ProjectModel activeProject = mapApp.ActiveProject;

    ProjectCollection progList = mapApp.Projects;

    DrawingSet dwgSet = activeProject.DrawingSet;

 

    try

    {

        // Check how many DWG files are attached and then Detach each of them

        while (dwgSet.DirectDrawingsCount > 0)

        {

            dwgSet.DetachDrawing(0);

            ed.WriteMessage("attached number: " + dwgSet.DirectDrawingsCount.ToString() + "\n");

        }

 

    }

    catch (MapException ex)

    {

        ed.WriteMessage(ex.Message);

    }

 }

Exporting DWG to SDF using *.epf file using Map 3D API

By Partha Sarkar

Want to export a DWG^TM file with Map 3D Object Data to a SDF file using .NET API? Autodesk.Gis.Map.ImportExport.Exporter API class has the required functionality to enable this export. However, in the past we had found some issues with it and the resultant export was not producing expected SDF file. With the release of AutoCAD® Map 3D 2012 SP1 exporting DWG to SDF using *.epf file through Autodesk.Gis.Map.ImportExport.Exporter API class is now operational.

Make sure to reference the ManagedMapApi.dll (C:\Program Files\Autodesk\AutoCAD Map 3D 2012\ManagedMapApi.dll) to your project. 

Here is a .NET code sample which demonstrates how to export a DWG file with Map 3D Object Data to a SDF file using Autodesk.Gis.Map.ImportExport.Exporter API – 

// AutoCAD Ref

using Autodesk.AutoCAD.Runtime;

using Autodesk.AutoCAD.ApplicationServices;

using Autodesk.AutoCAD.DatabaseServices;

 

// Map 3D Ref

using map = Autodesk.Gis.Map; 

 

namespace MapExport

{

    public class Class1

    {

        public static Autodesk.AutoCAD.EditorInput.Editor Editor

        {

            get

            {

                return Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;

            }

        }

 

        [CommandMethod("ADN_EXPORTSDF")]

        static public void ExportSDFTest() // This method can have any name

        {

            try

            {

 

                map.ImportExport.Exporter exporter = map.HostMapApplicationServices.Application.Exporter;

                exporter.Init("FDO_SDF", "C:\\Temp\\Street_Centerlines.sdf");

                exporter.LoadExportFormat("C:\\Temp\\Street.epf");

                exporter.Export();

 

                DisplayOutputMessage(string.Format("Export completed."));

            }

            catch (map.MapException ex)

            {

                map.Constants.ErrorCode errOdCode = (map.Constants.ErrorCode)ex.ErrorCode;

                MessageBox.Show("The following Map exception has occurred:\n\n" + errOdCode);

            }

            catch (System.Exception ex)

            {

                MessageBox.Show("The following exception has occurred:\n\n" + ex.ToString());

            }

        }

 

        static void DisplayOutputMessage(String str)

        {

            Editor.WriteMessage(str);

 

        }

 

    }

}
