Hi there,

I want to create a linestring and add it to the model in a certain graphicgroup.
Would anyone know how to do this? Problem is that ElementPropertiesSetter class does not seem to have something for this.
In the function to create the linestring, I have this:

    ElementPropertiesSetter propsSetter = new ElementPropertiesSetter();
    propsSetter.SetLevel(Bentley.MstnPlatformNET.Settings.ActiveLevelId);
    //  ...
    //Non existent:
    //propsSetter.SetGraphicGroup(Bentley.MstnPlatformNET.Settings.CurrentGraphicGroup);
    var retElem = new LineStringElement(Session.Instance.GetActiveDgnModel(), null, m_points.ToArray());
    propsSetter.Apply(retElem);

Best regards, Jan Willem

Hi,

I am trying to understand how to use DgnElementSetTool..

I want to locate element, accept located element and then process that element.

I think I need to use function " bool NeedAcceptPoint()". However I am not sure

when this function is actually called.

According to API documentation "Called after populating tool's ElementAgenda to see if an explict data point is required before accepting and calling _ProcessAgenda".

Which function populates ElementAgenda, is it BuildLocateAgenda?

This is my code (NeedAcceptPoint is never called):

        protected override bool OnDataButton(BDPN.DgnButtonEvent ev)
        {
            //Locate element.
            LocateOneElement(ev, true);
            BDPN.HitPath hitPath = DoLocate(ev, true, (int)BDPN.ComponentMode.Innermost);

           
            if (null != hitPath)
            {
                BDPN.Elements.Element sel_el = hitPath.GetHeadElement();
                if (sel_el.ElementType == BDPN.MSElementType.Line)
                {
                    BDPN.NotificationManager.OutputPrompt("Line Selected");
                    BuildLocateAgenda(hitPath, ev);

                    uint test = ElementAgenda.GetCount();
                    HiliteAgendaEntries(true);
                }
                else
                {
                    //OnRestartTool();
                }
                

            }

            return true;
        }

Appriciate any help

I had identified a missing function SystemCallback event 4 years ago here. It appears to still be missing.

CurveVector::IsPhysicallyClosedPath tells me if, say, a line-string has coincident start and end points.  It looks like a shape, but remains an open curve vector. 

I want to measure the area of that not-quite-a-shape.  Should I copy the line-string and create a closed CurveVector that I can measure?  Is there a CloseShape method I can call or should I extract the line-string points and create a new closed shape? 

CurveVector contains some arcane methods: is there another way to get a closed CurveVector from a CurveVector that passes the IsPhysicallyClosedPath test?

what's wrong with my program,maybe?Or something else?

Hi all, I am .NET developer and have been programming in .NET for the last 5 years. Moreover, I am starting to expand my skills so I picked up the most popular language, JavaScript nowadays for developers. 

I am creating a e-com based project  and need to add a generator for promo codes. Can anyone help me out? I have some design inspirations. 

Hello All,

I can create text node without subsctipt/superscript, I'd like to know how to create  subcript/superscript, can someone show me some sample code? Thanks a lot!

I have existing code that creates an IECInstance formatter for the area property of my Item Type. 

bool    CreateAreaFormatter  (IECInstancePtr&                 formatInstance,
                             int                              nUnits,
                             int                              accuracy,
                             Annotator::AreaDecoratorOptions  decorator)  
{
  ECN::ECSchemaPtr      formatSchema;
  if (SchemaFactory::GetMstnPropertyFormatterSchema (formatSchema))
  {
    WCharCP                 AreaClassName { L"AreaClass" };
    ECN::ECClassCP          formatClass   { formatSchema->GetClassCP (AreaClassName) };
    StandaloneECEnablerP    enabler       { formatClass->GetDefaultStandaloneEnabler () };
    StandaloneECInstancePtr localInstance { enabler->CreateInstance () };
    if (localInstance.IsValid ())
    {
      WCharCP        PropUnits       { L"Units" };
      ECValue        units           { nUnits };
      localInstance->SetValue (PropUnits, units);
      WCharCP        PropAccuracy    { L"Accuracy" };
      ECValue        valAccuracy     { accuracy };
      localInstance->SetValue (PropAccuracy, valAccuracy);
      WCharCP        PropUnitDecorator  { L"UnitDecorator"  };
      ECValue        valDecorator    { decorator };
      localInstance->SetValue (PropUnitDecorator, valDecorator);

      formatInstance  = localInstance;
    }
  }
  return formatInstance.IsValid ();
}

That uses the information in ECSchema..\MicroStation\ECSchemas\Standard\Units_Schema.01.00.ecschema.xml to obtain numeric conversions and labels.

I would like to create formatter for hectares.  Hectares are commonly used in Europe and rest of world to measure area.  Hectares are similar in scale to acres, used in the US.  Unfortunately, Hectares are not included in the MstnPropertyFormatter schema.

I have recorded a macro in microstation v8i ss4 and I have created a command button through userform in visual basic editor. But I am not able to place the command button in the drawing and run the macro. How should I link the command button to the macro so that when I place the command button in the drawing and when the user clicks on that button the macro should run.

Would someone to have the script txt, vba, mvba or macro to run batch process for rename

"Model" to "Design Model" (is the tab name from autocad on model space)

"Layout1" to Plot Model" (from autocad is the name of sheet number on paper space "r183hf01)

I know that I can manually rename by open one by one, it take to much time for a lot of dgn files

Please help

Thanks

I am using MicroStation Connect Edition Update 11 - Version 10.11.00.6, Windows 10, Visual Studio 2015 and .Net Framework for the project is set at 4.6.1.  I am trying to build the MicroStation Addin examples by Yongan Fu but I'm receiving errors on the example in Step 2.  My code is as follows:

Hi,

I'm trying to display a point cloud using the IPointCloudDrawParams. I managed to do this with the GetDPoints method. However it requires to keep my points as DPoint3d.  To save some memory I would prefer to use FPoint3d and GetFPoints method. The problem is that by using FPoint3d instead of DPoint3d I'm not able to keep a good precision for large coordinates. Is there a way to draw a cloud in a local coordinate system and then translate it to the proper position by adding a vector?

Thanks

I want to write a cell picker tool.  My goal is to modify a nested cell inside the picked cell element.

I started to write a picker class inheriting from DgnElementSetTool. On reviewing the MicroStationAPI help doc., I wonder if a class inheriting from ElementGraphicsTool would be a better choice?  There is no example of ElementGraphicsTool that would influence my decision.

Hi,

I have one model, it is an extended element containing a smart solid. /cfs-file/__key/communityserver-discussions-components-files/343173/2_5F00_SmartSolid.dgn

I trying to extract geometries using IElementGraphicsProcessor, but the callback would not be triggered. And if I drop the extended element in the application, the callback could be triggered.

My question is that is there any uniqueness for this model? How could I extract geometries for this extended element?

MicroStationAPI help lists a number of methods under topic Active Settings.  For example,

static BentleyStatus  GetValue (bool &value, ActiveBoolParams paramName) 
  Gets the value of an active MicroStation setting of type boolean 

However, those methods are in namespace ActiveParams not ActiveSettings.  Please make the documentation more accurate and helpful!

I am using OpenRoads Designer CONNECT Edition Release 4 Update 6 - Version 10.06.00.38.

I wrote a VBA script that uses element enumerator to scan for all text and will pass the current enumerator as a text element to a function. This function then determines the textstyle to apply.

A portion of the main module is below

            For Each omodel In o.ActiveDesignFile.Models
                oCriteria.ExcludeAllTypes' Scan for normal cells
                oCriteria.IncludeType msdElementTypeTextNode' Scan for shared cells
                oCriteria.IncludeType msdElementTypeText

                Set oEnumerator1 = omodel.Scan(oCriteria)
                Do While oEnumerator1.MoveNext
                
                    If oEnumerator1.Current.Type = msdElementTypeText Then
                        oEnumerator1.Current.IsHighlighted = True
                        
                        replaced_text = Text_StyleFix(oEnumerator1.Current.AsTextElement)
                        If replaced_text <> "" And InStr(replaced_text, ",") > 0 Then
                            oEnumerator1.Current.Rewrite
                            update_count = update_count + 1
                        Else
                            replaced_text = "None"
                        End If
                    End If

The text_stylefix function sets the text style using below. A string is returned for tracking purposes.

        Set oText.TextStyle = ActiveDesignFile.TextStyles(Replacement_Style)

Then I rewrite at the enumerator level. This line above updates all the text attributes other than the text name. Is there a reason the textstyle name is not being updated, but everything else is?

Thanks

I've got a "blank" (i.e. no SubItems) OptionButton definition in my resource file. I "insert" items dynamically using mdlDialog_optionButtonInsertItem(). When the OptionButton is displayed in the dialog, it contains the entries, but the DialogItem's "width" is zero (I have it set to 0 in the SExtent struct).

1.Is there any way to determine the "width" of a SubItem when inserted into the OptionButton? Just multiply the number of characters times some value (assuming fixed width font)?

2.If a width CAN be determined, is it possible to update the SExtent of the OptionButton so when it open, the "width" is set properly and you can see the entries?
