Deep in the abyss of my memory there is info that in AutoCAD API ObjectARX , there is function to get closed area arround known point but I don't remember name of this function. It works something simmilar to command _boundary, but not command which can be run by User interface, but clead ARX function . Can anybody remember name of this function?
For ObjectARX/C++, it is acedTraceBoundary
In .NET, it is Editor.TraceBoundary
