Catalog family Specify Types UI

[Anonymous]

Hello,

I have created a dockable window in Revit in which families are listed. If I click on family and drag it into active revit project, it gets placed at required location. It works well as of now for most of the families.

Now for catalog families, if I try to drag-drop the same, the 'Specify Types' UI does not appear using API.

I use following code for drag-drop

IDropHnadler iDrop = new IDropHandler();
UIApplication.DoDragDrop(/*list of family symbols*/, iDrop);

While manually inserting catalog family we get UI as shown below,

So my question is like, is there any other API method to call this ?

TIA

There is a method

UIDocument.GetPlacementTypes

so, you can create your own UI for this feature

Thank you for workaround. But I am looking if any direct API is available or not.

No, there is no such API. You should provide placement type in PromptForFamilyInstancePlacementOptions.FaceBasedPlacementType parametr of UIDocument method:

public void PromptForFamilyInstancePlacement(
	FamilySymbol familySymbol,
	PromptForFamilyInstancePlacementOptions options
)

I'm a liar, sorry. Yep, I found a workaround.

It is suitable to place user families.

First of all, you need to set default family symbol using Document.SetDefaultFamilyTypeId method.

Then get the command:

var revitCommand = RevitCommandId.LookupCommandId("ID_OBJECTS_FAMSYM");

Then check if it can be posted using UIApplication.CanPostCommand method. If it is true, then call:

uiApp.PostCommand(revitCommand);
