Description
This function will cause the AutoCAD input event mechanism to do a pick under the prevailing pick aperture on all digitizer events, regardless of whether a point is being acquired or whether any OSNAP modes are currently active. If a point is being acquired and OSNAP is active, the object snap aperture dimensions (system variable: APERTURE) define the pick box size. Otherwise the normal system variable PICKBOX value will be used. In the PointHistory enum, the following enum values are related to this capability, as indicated by their related comments: ForcedPick,ePickMask, DidNotPick, UsedPickBox, UsedOsnapBox.
A count is maintained, so that if multiple applications want to force picking, it occurs until they are all done.
