Viewport Specific geometry

[Anonymous]

Hi all,

I want to draw a viewport specific entity using AcGiViewportGeometry object. How could I display my custom entity only on the active viewport when I have more than one viewports in model space?       For example, I want to draw a polygon int the first viewport and  a circle in the second one.

Any help would be greatly appreciated

If you have a custom entity, you can write your own virtual method:

void myEntity::subViewportDraw(AcGiViewportDraw* mode)
{
        AcGiViewport &vp = mode->viewport();
	Adesk::ULongPtr id = vp.viewportId();

        AcGePoint2d lower_left, upper_right;
        vp.getViewportDcCorners(lower_left, upper_right);

	// Do your VP specific drawing depending on id or DC corners
}

subViewportDraw() will only be called, if your  myEntity::subWorldDraw(AcGiWorldDraw* mode)  returns  Adesk::kFalse.

Cheers
