It's used throughout the internal API, and also in the published API (see DgnECManager::GetInstanceCounts()).

Is there something you're trying to accomplish?

IElementPropertyEnabler won't be useful to you. If you want DGN element properties, whether in native or .NET, DgnECManager is usually the place to look.

You can try to get all instances available on a specific element. And then check if the individual instance has a specific property:

//ECQueryProcessFlags flags = intrinsic or extrinsic

ECInstanceList GetElementProperties(ElementHandleCR element, ECQueryProcessFlags…

I will use that in the future.

It should be possible to edit existing post as well.

I am trying to add 2 new members to the schema.

It would be possible, even when it's potentially risky operation.

I still have not been able to successfully attach an ItemType to anything using the ::SetElmDscrToFileFunction(). The same approach when used in a DgnElementSetTool::_OnElementModify() works fine. When inside the ::SetElmDscrToFileFunction() callback,…

Not sure if this is the correct way, but here is a solution I've come up with that adds an Item to an Element Template definition, once you have an ElementTemplateNodePtr :

Hi Jon,

Can you take a look at:

FUNC: FindInstancesOnElementForm

FindInstancesScopePtr     scope     { FindInstancesScope::CreateScope (*model, option) };

I need to get the ec instance of an item type instance that is attached to an element

Thanks Jan,

this is all very helpful. i was able to get a new instance added to the sub elements. but its only for the current session of microstation. once i close and reopen the sub elements no longer have the item attached. 

also im struggling with…

Hi Jon.

Thanks for the codes. Looks like the code is searching one instance on an element, and the scope is limited in specified schema. 

I am using similar codes which returns ECInstances for one element,

Hi Bruce,

If you only want to find a specific [ECShema:ECClass] on an element, I think it doesn't need to use WhereCriterion. Below is an example which can get [BaseElementSchema:MstnVolume] on an element.

void getVolumeByEC(WCharCP unparsed)
{

Hi Jon,

What am I doing wrong?

Based on some testing, I think the problem is how you define the scope. This code works fine with your design file:

FindInstancesScope scope = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnFile…

got this from Artur Goldsweer from Bentley Support. He said to get it from the EC data.

here is some code sample he gave me.
