IMPRINT command
Imprints 2D entities onto planar faces of 3D solids and surfaces to create additional edges.
Icon: 
Note: Use dynamic UCS (DUCS) to draw on the faces of 3D objects (UCSDETECT system variable =1).
方式
Select a 3D solid that has at least one flat face, a surface or a region entity. Select the source objects, 2D entities lying on or intersecting a planar face of the selected entity and after each choose if delete or keep the source object.
With the entities imprinted on the solid, you can use commands like EXTRUDE or DMPUSHPULL to manipulate the newly created faces, as shown below.
