how to achieve this editing interaction of AcDbEntity  by API ？ the entity will show "+" mark when it is selected, and you can click the "+" to pull out

Not easy, you need to use override of AcDbEntity::getGripPoints , AcDbEntity::moveGripPointsAt that use AcDbGripDataPtrArray ( AcDbGripData )

that way can draw the “+”？ and notify when the “+” is clicked

[daniel_cadext · Accepted solution]

AcDbGripData has worldDraw, viewportDraw. so you can draw your own custom glyph

use hotGripFunc for notification that it's hot.

it's pretty powerful, but not easy, the last sample I see is ARX2007\samples\entity\grip

unfortunately, it's been removed from current SDKs. or merged into some else
