Obtaining coordinates for point in drawing

[Anonymous]

Is there a way to convert between screen coordinates to drawing coordinates?

Thanks

Doing this is not trivial if you want to account for
things like paper space and model space viewports.

The DrawingEditor class in AcadX.arx has PixelToWorld()
and WorldToPixel() methods that will do it.

Tony,

Sounds like what I need but I am not sure how to call this function.

Function ScreenToWorld([Point], [VPortID])

Is point a POINTAPI type?
Does it return drawing coordinates in a variant?

Thanks

Point is an Array(0 To 1) of Integer, which
are the screen coordinates.

VPortID is the id of the viewport which the
transformation goes through (obviuosly, you
must identify a viewport), which corresponds
to the CVPORT system variable. If you omit
the Point argument, the current cursor location
is used. If you omit the VPortID argument, the
current viewport is used.

Tony,

That did the trick. Thanks for the fast response.
