Hi, Leidy If you want to create a point by giving the coordinates of it, it certainly can be created. Call GeometryModifyTool::make_RefVertex. There's no method in CGM to find the Vertex by location, this seems to be a graphics call. For example, if you have graphics layer on top of CGM, you should be able to draw a rectangle box and all ref-entities within this box will be selectable.

By example, I want create points in the space and I select a point by passing the coordinates. Thanks, Leidy
