AutoCAD .NET :: How To Code Drop-down List For Custom Property Using OPM

May 27, 2013

I am mainly developing for AutoCAD 2013/2014 how to implement a custom property as a drop-down list using OPM and .NET/C# wrapper. I have successfully created categorized custom properties already and can read/save them in XRecords via the OPM. I further implemented the members for IDynamicEnumProperty (using an ObjectARX DLL) in .NET/C# which are:

// ENUM-PROPERTY INTERFACE METHODS DEFINITIONenum myEnum{ steel = 0, copper, wood};public void GetNumPropertyValues( int numValues ){ numValues = 3;}public void GetPropValueName( int index, out String valueName ){ valueName = Enum.GetName(typeof(myEnum), index);}public void GetPropValueData( int index, ref Object valueName ){ valueName = index;}

And I have implemented the GetCurrentValueData() and SetCurrentValueData() members in my .NET/C# wrapper as per the IDynamicProperty2 interface as following:

public void GetCurrentValueData( Object pUnk, ref Object varData ) {AcadObject obj = pUnk as AcadObject; if ( obj != null ){using ( Active .Document.LockDocument( DocumentLockMode.ProtectedAutoWrite, null, null, true ) ){using ( var tr = Active.Transaction ){ObjectId ObjId = new ObjectId( (IntPtr) obj.ObjectID ); DBObject DbObj = tr.GetObject( ObjId, OpenMode.ForRead ); if ( DbObj != null ){try {if (

This code compiles without error but instead of the expected drop-down list the OPM only shows a field where I can enter or edit integer numbers, but there is no drop-down list when clicking on the field....

AutoCAD .NET :: How To Get Custom Property Names / Values From Custom Property Bag

Sep 15, 2011

I have been trying to find a method to extract custom properties from the custom property bag.

I have been able to extract the property value, using the "GetProperty" and the associated "GetValue" method, this method works when I know exactly what property name I am looking for. What do you do when you don't know the property name?

here is my code snippet..

dim myProps as acsmcustompropertybag = mysheet.getcustompropertybag
dim myProp as iacsmcustompropertyvalue = myprops.getproperty("SOMENAME")
dim myPV as string = myProp.GetValue

what I want to do is:

dim myProps as acsmcustompropertybag = mysheet.getcustompropertybag
dim myPN as string = ??????????.tostring
dim myProp as iacsmcustompropertyvalue = myprops.getproperty(myPN)
dim myPV as string = myProp.GetValue

AutoCAD Inventor :: ILogic - Set Custom Property In Custom Content Center Part

May 16, 2013

When using Inventor with Vault, we have a problem when categorizing custom content center parts in Vault. In short, custom content center parts are incorrectly categorized as "Content Center" and automatically released - as there is no property that we can use to identify these files.

I need iLogic code to trigger when custom content center files are created/saved, wich adds the following custom iproperty "IsCustomContentCenter=True".

AutoCAD Civil 3D :: Property List And Name Changes?

When I pick a feature line, the property dialog would show Feature line, and list the information.

Now for some reason, I get aecc_feature_line and the property dialog shows a different list of information.

How do I get back to the Feature line list.

AutoCAD .NET :: Unable To Get Custom Property Value

Sep 18, 2013

I am using AutoCAD 2014 and VB.NET 2010.  I am trying to get the value of a custom property and cannot seem to do so.

The old command I used for AutoCAD 2010 was:

ThisDrawing.SummaryInfo.GetCustomByKey(strParameter, strValue)

But this does not work anymore. So I created this sub but it does not seem to work either. 


Sub subFindCustomParam(ByVal strUserParameter AsString)    
Dim infoDB AsDatabase =Application.DocumentManager.MdiActiveDocument.Database
Dim infoBuilder AsDatabaseSummaryInfoBuilder = NewDatabaseSummaryInfoBuilder(infoDB.SummaryInfo)

AutoCAD Inventor :: Sketched Symbol With Custom Property

Nov 30, 2011

I am trying to create a sketched symbol on the fly that has custom properties in it. I am also creating the custom properties on the fly. I need to get the actual expression for the property into the sketched symbol not just a value. I need this so that I can export the drawing as an autocad .dwg that has attributes in it.

AutoCAD .NET :: Sheet Set Custom Property Field TransmittalSetups?

Dec 12, 2012

The SheetSetObject has an inbuilt custom property called "TransmittalSetups", but the property has a different internal object structure compared to other CustomProperty 



Dim myPropEnum As IAcSmEnumProperty = myCPB.GetPropertyEnumerator
Dim myPropName As String = Nothing
Dim myPropValue As AcSmCustomPropertyValue = Nothing

myPropEnum.Next(myPropName, myPropValue)


myPropName is a string, and in this instance it returns a value of "TransmittalSetups"

myPropValue.GetValue is a string, and it says "System.__ComObject" not a "value".

So my question is, how do identify this object, how to interigate it or assign it to its native object type.

I have tried to cast it to different IAcSmEnum types but without success.

CorelDRAW Graphics Suite X4 :: Drop Shadow Property Bar Attributes Disappears?

May 19, 2011

X4. When I add a drop shadow to anything the variable attributes do not appear on the property bar, ie "flat bottom right" at top left and then the choice of colours etc. I know by now where they are so click on where I think they are, but it's annoying. I have deleted, run a reg cleaner and re-installed + added the SP2 updates.

AutoCAD Inventor :: Getting A Drawing Border To Act On A Modified Custom Property

Feb 20, 2012

The company I work for produce drawings for various types of fabrication.

Using Inventor I have a drawing border in which tolerance values change depending on the type of fabrication to be produced. The type of fabrication (0,1,2,or 3) is designated by a custom property entered during part/fab model creation.

This property may change depending on various production factors. The issue I have is how do I get the border to recognize this potential change in fab type and populate the tolerance fields with the necessary information?

AutoCAD Architecture :: Custom Property Set Definitions To Add Information To Spaces

Dec 13, 2013

I am using some custom property set definitions to add information to spaces.  However as I insert spaces I find that I have to go to the extra step to add the property set to the object using the Extended Data tab in the Properties Palette. 

It is not a huge deal but sometimes it is forgotten and schedules are not reporting properly, or the display theme is not correct.  Although there are tools to quickly add them I would like to know if there is an automatic way to add them while creating the spaces/zones.

On a related note.  There is a property set definition that is in each file by default called RoomFinishObjects.  Is there a way to purge this?  I don't want to attach finishes to my objects.  But it seems to be embedded in the file.

AutoCAD Inventor :: Keeping Custom Property Date Blank

Mar 22, 2013

My company has a custom property named 'Released date, Type Date.

This date is still empty

I am working on a rule that adds all the custom properties required for the company title block.

This rule can be useful whenever you get a model from a supplier.

I can add a custom property date using the following

Dim oDoc As Document = ThisApplication.ActiveDocument
Dim customPropertySet As PropertySet = oDoc.PropertySets.Item("Inventor User Defined Properties")
iProperties.Value("Custom", "Released Date") = iProperties.Value("Custom", "Released Date")

This code works but sets the released date to Now.

But the release date needs to remain blank when adding.

I tried to make the value Null but I get the error:

"Value of type 'System.DBNull' cannot be converted to 'Date'."

Is there a way to keep a custom property date blank?

AutoCAD 2010 :: Modify Sheet Set Custom Property Definitions

May 3, 2012

I FINALLY decided to get my head around the Sheet Set Manager (kudos to Kate Morrical's video series).

I understand the need to create custom properties, and I can see that you can either "add" or "delete" custom properties, but is there any way to CHANGE the property after it's been defined?

For example, if I create a custom property complete with a default value, but discover later that I made a spelling mistake (eg. "Darwn By" instead of "Drawn By"), is there any way to MODIFY it?

AutoCAD 2013 :: Sheet Set - Adding Space To Default Custom Property

Jul 18, 2013

I'm tasked with setting up a new dwt file to be used along with the Sheet Set Manager.

I've got as far as adding in my own custom properties at both the Sheet Set level (things like project name, site name, etc.), and at the Sheet level (drawing title).

But more specifically, at the Sheet Level, I want to be able to facilitate having a multi-line drawing title. Things start to get a little cloudy.

In order to be able to control where the line breaks are, I've simply created 5 fields (3 for an odd number of lines, 2 for even), and I want to set their Default Value so they don't display anything, i.e. a space or blank of some kind, instead of the four dots. So when I want to add the title I go to the Sheet properties and change the value.

I thought it'd be as simple as adding the ASCII code for a space (U+00A0) into the Default Value, but that seems to display the text U+00A0 instead of the space.

AutoCAD Inventor :: Custom Property Link From Drawing To Part Breaks

Jul 14, 2012

I'm trying to see if I can write a rule that will link a custom property at the part level in a template and have it update when I copy the part and drawing to a new design.  Below is the formula I'm using and it works in the original files but when I use Design Assistant to create a copy for a new design, this formula will not update.

iProperties.Value("Custom", "Title")=Parameter("Bearing_#01.ipt.Build_Title")

AutoCAD Inventor :: Change Custom Property Format From Assembly Level

Apr 8, 2013

I have a frame fabrication / assembly with a Custom iProperty called "FINISHED MATERIAL SIZE". I have set the following parameter for this property:

FINISHED MATERIAL SIZE = <Stock Number> x <G_L>mm

This returns the stock size and length to my drawing cutlist. The problem is that the <G_L> Parameter returns the trailing zeros and unit string.

I would like to set all the frame members in the assembly such that the G_L parameter returns a value rounded off to 0 decimal places with no trailing zeros and removes the unit string as well.

Is there a way I can achieve this from the assembly so I don't have to manually open each frame member and make the changes in the fx parameters dialog one at a time?

AutoCAD 2010 :: Import / Exp​ort Layer Property Custom Filters

Nov 14, 2012

I need importing and exporting custom layer property filters. Long story short, we XREF a lot of mechanical equipment in our models and when we create a structural drawing make all of the mechanical item print in a light ghosted color. I created a layer property filter with a huge list of all the possible equipment prefix's like *cl-* *tk-* *rv-* and so on to filter out all the equipment layers. It took a long time to create, so I want to export it and import it into future drawing.

AutoCAD Civil 3D :: Expressions Losing Custom Pipe Property Reference

Jun 28, 2012

Having problems using custom pipe properties in pipe label expressions in 2013? I have some expressions relating to stub callouts and the ones that directly reference the custom properties lose that reference every so often.

For example I have and expression called "STUB-Riser-Length2d" which is defined as "{Riser Length} / SQRT(2)" where "Riser Length" is the custom pipe property. Every week or so it changes to "/ SQRT(2)".

I haven't been able to find the pattern as to exactly when this happens yet. All expressions not referencing custom properties seem to be holding steady. The pipe catalog is on a shared drive on the network, if that makes any difference.

Is it possible to code a custom linetype, so that it only follow certain annotation scales (e.g. 1:100, 1:200 1:500) and so that it just appears as a continuous line below and above these certain scales?

The solution should work even when the drawing is used by others and apply to both modelpsace and paperspace (viewport).

AutoCAD .NET :: How To Implement Drop-down List (based On IDynamicEnumProperty) In OPM

May 25, 2013

Is there somone who can explain/show a sample of how a custom drop-down list in OPM can be implemented? Based on some articels by Kean Walmsley, I have successfully implemented categorized properties in the OPM using a .NET wrapper and C#. I have a class imlementing the members of the  IDynamic EnumProperty, ICategorizeProperties and IDynamicProperty2 interfaces (based on ObjectARX 2013).

However, I do not really understand how to code custom drop-down list using .NET wrapper and OPM. I am using AutoCAD 2013 and 2014. I have read a lot of posts regarding OPM but there was no useful information in regards to create custom drop-down lists.
