[Connect - C++] FenceManager - set clip mode

Question

Hi all 
 i would like to use a fence and set the clip mode but I can't make it work. Here is my code: 
 virtual StatusInt _OnElementModify(EditElementHandleR eeh) override
{
	if (eeh.GetElementType() == ELLIPSE_ELM)
	{
 FenceManagerR fenceManager = FenceManager::GetManager();
 IndexedViewSetR viewSet = IViewManager::GetManager().GetActiveViewSet();
 fenceManager.DefineByElement(&eeh, viewSet.GetViewport(tcb->lstvw));
 FenceParamsP fenceParams = FenceParams::Create(ISessionMgr::GetActiveDgnModelP());
 fenceManager.InitFromActiveFence(*fenceParams, false, true, FenceClipMode::Original);
 lifalib_dmsg("clipMode1 = %d", fenceManager.IsClipMode());
	}
} 
 The isClipMode method in the FenceManager returns 0 (false) but I expected it to return true while the doClip parameter of the InitFromActiveFence is set to true. 
 What am I doing wrong ? 
 Regards, Evan

FenceManager::BuildAgenda just returns the set of persistent elements that satisfy the FenceParams, it's doesn't modify them. So, in the case of clip, it's treated the same as overlap. 
 
You can then use FenceManager::ClipElement and decided how you want to handle the inside/outside pieces. In your case, it sounds like you want to keep deleting the original like you are already doing, but then also add the outside clip result agenda entries to the model.
