1、切換到移動工具，並選擇當前圖層。
/iknow-pic.cdn.bcebos.com/d6ca7bcb0a46f21f514d2cb9f8246b600d33aedb"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d6ca7bcb0a46f21f514d2cb9f8246b600d33aedb?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/d6ca7bcb0a46f21f514d2cb9f8246b600d33aedb"/>
2、（前提是移動工具時）按住Alt鍵拖動當天圖層內容，如果要鎖定水平、垂直或者45°角移動復制，可以同時按住Shift鍵，快速實現拖動復制圖層。完成。

第二種方法：右鍵復制圖層
1、矩形選框工具或者套索工具時，在圖層上右鍵單擊，選擇復制圖層。
/iknow-pic.cdn.bcebos.com/503d269759ee3d6d8a5cf5214d166d224e4ade46"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/503d269759ee3d6d8a5cf5214d166d224e4ade46?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/503d269759ee3d6d8a5cf5214d166d224e4ade46"/>
2、在彈出的復制圖層對話框中輸入新復制圖層的名稱，下面的目標選擇本文檔（如果要復制到其他文檔可以選擇其他文檔）
/iknow-pic.cdn.bcebos.com/54fbb2fb43166d22ace2677e482309f79152d247"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/54fbb2fb43166d22ace2677e482309f79152d247?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/54fbb2fb43166d22ace2677e482309f79152d247"/>
3、快速復制圖層成功。完成。
