How to hide the boundary line of the model?

[SimonaQQ]

Hello,

I want to hide the boundary line of a model in the view, such as the two walls in the picture. One wall has a certain boundary hidden in the current view. I can hide it manually, but I can't find the API to get and hide these lines. So is there such an API? Please let me know.
In addition, I found that the explanation in the viewdisplayedges enumeration is very consistent with the scenario I want to implement at present, but I can't find the method in which this enumeration is used, so is this method not disclosed?
thank you

No it isn't obvious where ViewDisplayEges would be used or even why it exists considering it is either 0 or 1.

Not seen any functionality in the API reminiscent of the linework tool in the UI. Would assume this would be done via graphics styles applied to edges however with that tool you can split the edge and change it's visibility extents.  So not seen anything to accommodate that in the API.
