DMEXTRUDE command

Creates 3D solids or surfaces by extruding entities.

Icon:

描述(D)

Creates 3D solids or surfaces by extruding opened or closed 2D entities, faces of 3D solids, regions or closed boundaries.

Note: The SELECTIONPREVIEW system variable must be set to 2 or 3 to highlight faces.

方式

There are two methods to extrude entities:

  • Create 3D solids.
  • Create surfaces.

Options within the command

模式(MO)
Allows to create either solids or surfaces.
实体(SO)
Creates 3D solids.
曲面(SU)
Creates surfaces.
Note: DMEXTRUDE does not extrude open 2D entities as 3D solids because they cannot be watertight.
指定挤出高度
Allows to set a height of extrusion. The extrusion height is measured perpendicularly to the source entity.
自动
The result depends on the extrusion direction and the value of DMEXTRUDEMODE system variable.
  • When you highlight an entity and extrude it to the outward, a new volume is added.
  • When you highlight an entity and extrude it to the inward, a volume is subtracted from the main solid.
创建(A)
A new volume or surface is created, regardless of the extrusion direction.
差集
The 3D solid is subtracted from each interfering existing solid.
并集
The new 3D solid is unified with each interfering existing solid.
分割(S)
Cuts through solids with the extruded surface.
  • Select an entity to be extruded.
  • The extruded surface cuts through solids.
两侧
Extrudes symmetrically in both sides.
锥形角度
Specifies the taper angle for the extrusion. The angle is measured from the extrusion direction. A negative value tapers outwards.
set Direction
Allows to specify the extrusion direction.
2点(2P)
Define the extrusion direction by specifying two points.
X轴
Sets the extrusion direction parallel to the X axis of the current UCS.
Y轴
Sets the extrusion direction parallel to the Y axis of the current UCS.
Z轴(Z)
Sets the extrusion direction parallel to the Z axis of the current UCS.
set Limit
Allows to limit the extrusion by the face of a solid.
  • Select an entity to be extruded.
  • Select a face as limit of the extrusion.
