Autodesk ObjectARX

[#1]

Hi,

I have complex custom entities and I'd like to implement advanced manipulation like grip points of Polyline. I'm looking for how to draw a custom glyph neer the AutoCAD crosshair cursor, like AutoCAD does when you convert a polyline segment to an arc or you add a vertex (look at the image below).

All suggestions are welcomed.

Best regards,

Jonathan

For example with help of AcEdInputPointMonitor::monitorInputPoint.

Using AcGiViewportDraw* drawContext parameter you can draw yours own graphics.
