Draft Settings in AutoCAD (3D Object Snap)

3-D Object_Snap setting controls the dynamic object_snap settings for 3-D object.

With dynamic 3-D Object_Snap setting, also called Osnap setting, you may signify the snap point at the specified position on the objects. When more than one option are choosen, the choosen snap mode is applied to give a point closer to_center of  aperture_box. Press TAB to jump on the option.
List of available Option
3-D Object_Snap [On/off]
It Turn 3-D Object_Snap on and off. The 3-D Object_Snap selected under 3D Object_Snap Mode is active while Object_Snap is on. [3DOSMODE system variable]
Object_Snap Mode
Lists the 3D Object_Snap mode.
Vertex_
It Snap to closer vertex of a 3-D objects.


Midpoint_on_Edge
It Snap to the mid_point of face edges.

Center_of_Face
It Snap to center_of_face.

Knot_
It Snap to a knot_ on splines.

Perpendicular_
It Snap to a points perpendiculars to face.

Nearest_to_Face
It Snap to points that is near to a 3-D object faces.

Point_Cloud
It Turn points cloud objects snap on and off. Points cloud objects snaps are running while Object_Snap is on. [3DOSMODE system variable]
Node_
It Snap to nodes on point cloud whether or not it contain segmentation datas from ReCaps processings.
Nearest_to_plane

It Snap to the near points on a planar segments on a points cloud. When a points is detected that is parts of a planar segments, the snaps connect to the planes of that segments. The planar segments will displays as you acquires the points if segments highlighting is turned ons. Requires segmentations data from Autodesk_ReCap.
Perpendicular_
It Snap perpendiculars to a planar segments on a points cloud. When a points is detected that belong to a planar segments, the snaps connects to it from a points perpendiculars to the planes of that segments [similar to a snaps perpendiculars to the faces of a solids]. The planar segments will displays as you acquires the points if segments highlighting is turned on.
Select_All
It Turn on all 3-D Object_Snap mode.
Clear_All
It Turn off all 3-D object snap mode
