Enable Hyperlink in Selection panel of Fusion Viewer

By Daniel Du

If you are migrating your application from Ajax Viewer(aka. Basic web layout) to Fusion Viewer(aka. Flexible web layout), you may notice that the hyperlink in selection panel does not work, it displays as raw HTML tags.

(In Fusion Viewer, not as expected )

(in Ajax Viewer, works well)

Here is the solution, you need to edit SelectionPanel.js in C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2013\www\fusion\widgets. Search “renderFeature”(Around 384) and change code as below:

htmlDecode:function(str){
	var s = "";
	if(str.length == 0) return "";
	s =  str.replace(/>/g,   ">");
	s =  s.replace(/&lt;/g,     "<");
	s =  s.replace(/&nbsp;/g,   " ");
	s =  s.replace(/'/g,        "\'");
	s =  s.replace(/&quot;/g,   "\"");
	s = s.replace(/<br>/g,      "\n");
	return s;
},

renderFeature: function() {
var layerIdx = this.layerList.selectedIndex;
var featureIdx = this.featureList.selectedIndex;
var layerObj = this.oSelection.getLayer(layerIdx);
var nProperties = layerObj.getNumProperties();
var aNames = layerObj.getPropertyNames();

var table = document.createElement('table');

var thead = document.createElement('thead');
var tr = document.createElement('tr');
var th = document.createElement('th');
th.innerHTML = OpenLayers.i18n('attribute');
tr.appendChild(th);
var th = document.createElement('th');
th.innerHTML = OpenLayers.i18n('value');
tr.appendChild(th);
thead.appendChild(tr);
table.appendChild(thead);

var tbody = document.createElement('tbody');
table.appendChild(tbody);
for (var i=0; i<nProperties; i++) {
	var tr = document.createElement('tr');
	if (i%2) {
		tr.className = 'oddRow';
	}
	var th = document.createElement('th');
	th.innerHTML = aNames[i];
	var td = document.createElement('td');
	td.innerHTML = this.htmlDecode(layerObj.getElementValue(featureIdx, i));
			
	tr.appendChild(th);
	tr.appendChild(td);
	tbody.appendChild(tr);
}
this.featureDiv.innerHTML = '';
this.featureDiv.appendChild(table);
}

The idea is to decode the string value so that it can be rendered correctly. Please pay attention to the comma at the end of the the htmlDecode() function. Of cause you may add this utility function somewhere else to make the whole fusion project more organized, I just add it into SelectionPanel.js for simplicity.

Finally, you need to change the Javascriipt reference to the fusion.js in your template index.html, for example, C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2013\www\fusion\templates\mapguide\slate\index.html if you are using Slate template:

<script type="text/javascript" src="../../../lib/fusion.js"></script>

TBBatch.exe throws an XmlConfigurator error in AutoCAD Map 3D 2012 Enterprise

By Partha Sarkar

Some of you might have noticed an issue in using the TBBatch.exe in Map 3D 2012 Enterprise. TBBatch.exe throws exceptions like the following - 

log4net:ERROR XmlConfigurator: Error while loading XML configuration 
System.Xml.XmlException: Ungültiges Zeichen in der angegebenen Codierung. xxxx 
58, Position 1. 
in System.Xml.XmlTextReaderImpl.Throw(Exception e) 
in System.Xml.XmlTextReaderImpl.Throw(String res, String arg) 
in System.Xml.XmlTextReaderImpl.Throw(Int32 pos, String res) 
in System.Xml.XmlTextReaderImpl.InvalidCharRecovery(Int32& bytesCount, Int32 & charsCount) 
in System.Xml.XmlTextReaderImpl.GetChars(Int32 maxCharsCount) 
in System.Xml.XmlTextReaderImpl.ReadData() 
in System.Xml.XmlTextReaderImpl.EatWhitespaces(BufferBuilder sb) 
in System.Xml.XmlTextReaderImpl.ParseRootLevelWhitespace() 
in System.Xml.XmlTextReaderImpl.ParseDocumentContent() 
in System.Xml.XmlTextReaderImpl.Read() 
in System.Xml.XmlLoader.LoadDocSequence(XmlDocument parentDoc) 
in System.Xml.XmlLoader.Load(XmlDocument doc, XmlReader reader, Boolean preserveWhitespace) 
in System.Xml.XmlDocument.Load(XmlReader reader) 
in log4net.Config.XmlConfigurator.Configure(ILoggerRepository repository, Stream configStream)

 

To make TBBatch.exe functions correctly, unzip the attached config file and then try to copy the same file to the bin directory and rename the file to ‘TBBatch.exe.config’. This should help in resolving the above mentioned issue.

Accessing AutoCAD Civil 3D Alignment Design Speeds using .NET API

By Partha Sarkar

For a given Alignment object in AutoCAD Civil 3D, we want to find out the all the 'Station' values and the corresponding 'Design Speed' as shown in the screenshot below -

 

We can access these values using DesignSpeed class in Civil 3D .NET API.

Here is a relevant code snippet in C# -

 

Alignment objAlignment = trans.GetObject(alignmentId, OpenMode.ForRead) as Alignment;

 

foreach (DesignSpeed objDS in objAlignment.DesignSpeeds)

{

 

  ed.WriteMessage("\n\tDesign Speed Number :{0} -- Start Station: {1} --- Design Speed Value :{2}",

    objDS.SpeedNumber.ToString(), objDS.Station.ToString(), objDS.Value.ToString() );                      

 

}

Hope this is useful to you!

AutoCAD Map 3D API Training content : Part-1

By Partha Sarkar

Most of you working on customizing and application development on AutoCAD Map 3D must be aware of broad range of API support in Map 3D which includes ActiveX, AutoLISP, ObjectARX, Geospatial Platform, Feature Data Objects (FDO) and Industry Data Model (aka Topobase) API. 

 

Here is a quick highlight of these APIs and their supported technology platform - 

ObjectARX and FDO are exposed as C++ and also .NET. 

Geospatial Platform is exposed as .NET only. 

Industry Data Model (aka Topobase) API gives access to Industry Data Model (aka Topobase) feature and functionalities in Map 3D using .NET. 

ActiveX and AutoLISP cover Autodesk Data Extension functionality (ADE), which includes drawing sets, queries, and object data. 

AutoLISP also covers map plotting and topology.

 

AutoCAD Map 3D Wikihelp (http://wikihelp.autodesk.com/AutoCAD_Map_3D ) contains online API reference documents and the related Developer's guide which are very detailed and helpful in application development on Map 3D.

 

So, why am I writing all these which are nothing new to Map 3D developers and developer community? Ok, here is the reason - We have thought to publish the relevant Map 3D API training content through our Infrastructure Modeling DevBlog (http://adndevblog.typepad.com/infrastructure/ ).

In a series of blog posts in the coming days / months you will see most of the Map 3D API training content (PDF and code samples) will be published here. In today's post I am attaching the Map 3D Geospatial Platform API Overview Chapter 1.

 

Hope this is useful to you!

Resolving Style conflicts in exporting Civil 3D Object styles using .NET API

By Partha Sarkar

StyleConflictResolverType Enumeration specifies how to resolve conflicts (the same name for an existing style and a new imported style) when exporting styles to another drawing using StyleBase::ExportTo(). 

Members of  StyleConflictResolverType Enumeration - 

CancelRemaining
Rename
Ignore
Override

Here is a C# .NET code snippet which demonstrates how to use Autodesk.Civil.StyleConflictResolverType in resolving conflicts -

 

LabelStyleCollection lStyles = civilDoc.Styles.LabelStyles.PointLabelStyles.LabelStyles;

foreach (ObjectId stId in lStyles)

{

  LabelStyle pSt = trans.GetObject(stId, OpenMode.ForRead) as LabelStyle;

  // Export the style

  pSt.ExportTo(outDb, Autodesk.Civil.StyleConflictResolverType.Override);

  // Now export its children

  for (int i = 0; i < pSt.ChildrenCount; i++)

  {

    LabelStyle chSt = trans.GetObject(pSt[i], OpenMode.ForRead) as LabelStyle;

    chSt.ExportTo(outDb, Autodesk.Civil.StyleConflictResolverType.Override);

  }

}

Hope this is useful to you!

Is there a .NET equivalent for ade_projentityforward ?

By Partha Sarkar

ade_* functions are not exposed in the .NET API. We can work around this by defining a LISP command and calling ade_* function in it and then in .NET application invoke the command defined in LISP. See the bellow codes.

(defun c:LispADE ()
(setq cscode (ade_projgetwscode))
(if (= cscode null)
(progn
(alert "Error in getting current coordinate system!")
(exit)
)
)
(setq rt (ade_projsetsrc "LL84"))
(if (/= rt t)
(progn
(alert "Error in getting current coordinate system!")
(exit)
)
)

(setq rt1 (ade_projsetdest cscode))
(if (/= rt1 t)
(progn
(alert "Error in setting destination coordinate system!")
(exit)
)
)
(setq entdata (car (entsel "select entity:")))
(setq rt2 (ade_projentityforward entdata))
(if (/= rt2 t)
(progn
(alert
"Error in projecting entity to destination coordinate system!"
)
(exit)
)
(alert "ok")
)

)

The .NET invoking code is here:

[CommandMethod("MyADE")]

public void InvokeAdeFun()

{

  Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.SendStringToExecute("LispADE", false, true, false);

}

 

Hope this is useful to you!

 

Accessing Child Object Style using .NET API

By Partha Sarkar

In this particular example we will see how to access Civil 3D Surface Spot Elevation Child label style. Suppose there is a Surface Spot Elevation Child label style named "Foot Meter_Child" in a Civil 3D DWG file and we try to use the following VB.NET code snippet to find out the number of Spot Elevation label style in the same DWG file, child label styles won't be shown or counted as shown in the screenshot below -

Dim surfaceSpotElevnLblStyle As LabelStyleCollection = civilDoc.Styles.LabelStyles.SurfaceLabelStyles.SpotElevationLabelStyles

MsgBox("This DWG File has : " + surfaceSpotElevnLblStyle.Count.ToString + " Surface Spot Elevn Label Styles !")

 

 

Above code snippet shows the count of 'Spot Elevation' labels as two omitting the child label style.  So how do we access Child Object Style using .NET API ?

We can access child label style from the parent label style's ObjectId using [index]. Here is the relevant VB.NET code snippet -

 

Try

 

    Dim surfaceSpotElevnLblStyle As LabelStyleCollection = civilDoc.Styles.LabelStyles.SurfaceLabelStyles.SpotElevationLabelStyles

    'MsgBox("This DWG File has : " + surfaceSpotElevnLblStyle.Count.ToString + " Surface Spot Elevn Label Styles !")

 

    Dim surfaceLblStyleId As ObjectId = Nothing             

    Dim osurfaceElevnLabelStyle As LabelStyle  = Nothing

 

    For Each surfaceLblStyleId In surfaceSpotElevnLblStyle

      osurfaceElevnLabelStyle = trans.GetObject(surfaceLblStyleId, OpenMode.ForRead)

      MsgBox("Style Name : " + osurfaceElevnLabelStyle.Name.ToString + "  " + "Children Style Count : " + osurfaceElevnLabelStyle.ChildrenCount.ToString)

      If (osurfaceElevnLabelStyle.ChildrenCount >0) then              

          Dim childLblStyleId As ObjectId =   osurfaceElevnLabelStyle(0)

          Dim childLblStyle As LabelStyle = trans.GetObject(childLblStyleId, OpenMode.ForRead)

          MsgBox("Child Style Name :" + childLblStyle.Name.ToString)                          

 

      End If

    Next        

 

    trans.Commit()        

Catch ex As Exception

    ed.WriteMessage("Exception Message is : " + ex.Message.ToString())

Exit Sub

End Try

Autodesk.Map.IM.Display.GraphicsGeneration.GraphicsGeneratorFactory is obsolete!

By Partha Sarkar

If you are trying to create an instance of IGraphicsGenerator in Map 3D 2013 from GraphicsGeneratorFactory.Instance, you might see the following compiler error - 

Autodesk.Map.IM.Display.GraphicsGeneration.GraphicsGeneratorFactory' is obsolete: 'No longer supported; the graphic generator is no longer a singleton. It is a service instead, use Application.Services.GetService<IGraphicsGenerator>().' 

Public Shared ReadOnly Property Instance As Autodesk.Map.IM.Display.GraphicsGeneration.IGraphicsGenerator' is obsolete: 'No longer supported; the graphic generator is no longer a singleton. It is a service instead, use Application.Services.GetService<IGraphicsGenerator>().

 

In Map 3D 2013 Industry Data Model API, you can access IGraphicsGenerator  like below :

Dim gg As IGraphicsGenerator =

  Me.Application.Services.GetService(Of Autodesk.Map.IM.Display.GraphicsGeneration.IGraphicsGenerator)()

 

If gg Is Nothing Then

    Me.Application.MsgBox("Graphic generator is not registered.")

    Return

End If

Creating Surface Spot Elevation Label using Civil 3D .NET API

By Partha Sarkar

In AutoCAD Civil 3D, we can create different types of Labels for a Civil 3D Surface object. In the screenshot below, we can see from Annotation Tab, using the Add Labels, we can add a spot Elevation Label, Contour Label etc. for a Surface object.

Civil 3D .NET API has equivalent functions for creating Labels programmatically for many of these options as shown in the above screenshot.

If you want to create Surface Spot Elevation Label or Contour Label, you can use the following API -

SurfaceElevationLabel.Create() 

SurfaceContourLabelGroup.Create() 

 

In this C# .NET code snippet below, we can see how to create TIN surface spot elevation -

//select a surface

PromptEntityOptions selSurface = new PromptEntityOptions("\nSelect a Tin Surface: ");

selSurface.SetRejectMessage("\nOnly Tin Surface is allowed");

selSurface.AddAllowedClass(typeof(TinSurface), true);

PromptEntityResult resSurface = ed.GetEntity(selSurface);

if (resSurface.Status != PromptStatus.OK) return;

ObjectId surfaceId = resSurface.ObjectId;

 

//select a Point to Add Elevation Label

PromptPointOptions ppo = new PromptPointOptions("\nSelect a Point to Add Spot Elevation Label: ");

PromptPointResult ppr = ed.GetPoint(ppo);

if (ppr.Status != PromptStatus.OK) return;     

 

// Prepare the Elevation

double x = ppr.Value.X;

double y = ppr.Value.Y;

Point2d pnt2d = new Point2d(x, y);

 

Database db = Application.DocumentManager.MdiActiveDocument.Database;

using (Transaction trans = db.TransactionManager.StartTransaction())

{

  try

  {

 

    // create the spot elevation using SurfaceElevationLabel.Create

    ObjectId surfaceElevnLblId = SurfaceElevationLabel.Create(surfaceId, pnt2d);

    SurfaceElevationLabel label = surfaceElevnLblId.GetObject(OpenMode.ForRead) as SurfaceElevationLabel;

    ed.WriteMessage("\nSurface Spot Elevation Label created and Style Name is :" + label.StyleName.ToString());

    trans.Commit();

  }

 

  catch (Autodesk.AutoCAD.Runtime.Exception ex)

  {

    ed.WriteMessage("\n Exception message :" + ex.Message);

  }

}

 

And here is the result -
