allegro15.2中的复制电气元件等是怎么设的

如果你要的器件已经在板上了，当然不能LOGIC>ASSIGN REFDES了。

最好把你的情况通过截图的方式表达出来。

图不会贴啊,下面是是COPY上面的部分.书上是这么说的,我试不出来啊.Copying Elements in a DesignYou can duplicate one or more elements in a design as:
Individual elements
Step and repeat patterns on an X,Y (rectangular) grid
Radial (polar) patterns around a user-defined pointUse the Options tab to control the copy method as Rectangular (step and repeat patterns)or Polar as described next.When you choose Edit – Copy (copy command), you can choose one or more elements,including package/part symbols and their connecting etch/conductor and vias, and placecopies of the elements, as a group, anywhere in a drawing. Reference designators of copiedpackages are changed to generic reference designators (U*, R*, C*, and so on) so they donot conflict with any existing reference designators in the drawing. Choose Logic – AssignRefDes (assign refdes command) to assign reference designators to the copiedcomponents.You create arrays of packages and connecting etch/conductor lines by picking a “cell” ofpackages and connecting etch/conductor lines, and then copying the cell. It is particularlyuseful that copy automatically connects connecting etch/conductor lines with the pins theyoverlay during the copying. This means that all power, ground, bus, address, and data linesautomatically connect to the pins of copied components.

In the following illustration, the copy appears at the location picked. Note that the referencedesignators have been changed to dummies. Each refdes has its leading characters, but hashad its number changed to *.

不用其他设置的，你首先要把你要copy的那部分symbol从板子上删除，然后就可以assign了

太感谢了,3Q,我可以加你吗
