三d圖紙轉pdf為什麼丟東西

㈠ CAD圖紙怎麼轉PDF

cad轉換成PDF格式後是空白的是由於未成功選擇要轉換的范圍，具體解決步驟如下：
1、首先打開cad圖紙一份，點擊左上角圖標，會彈出下拉框，點擊輸出按鈕。
/iknow-pic.cdn.bcebos.com/7acb0a46f21fbe09cb4961fa65600c338644adcd"target="_blank"title="點擊查看大圖"class="illustration_alink">/iknow-pic.cdn.bcebos.com/7acb0a46f21fbe09cb4961fa65600c338644adcd?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/7acb0a46f21fbe09cb4961fa65600c338644adcd"/>
2、點擊輸出按鈕之後，就會出現轉換文件的格式，選擇轉換成pdf格式即可。
/iknow-pic.cdn.bcebos.com/d31b0ef41bd5ad6eec36c6048fcb39dbb7fd3c14"target="_blank"title="點擊查看大圖"class="illustration_alink">/iknow-pic.cdn.bcebos.com/d31b0ef41bd5ad6eec36c6048fcb39dbb7fd3c14?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d31b0ef41bd5ad6eec36c6048fcb39dbb7fd3c14"/>
3、此時，電腦會彈出一個對話框，選擇修改文件的名稱，點擊需要轉換的窗口文件進行選擇。
/iknow-pic.cdn.bcebos.com/359b033b5bb5c9eaa7e2a10ddb39b6003bf3b3cf"target="_blank"title="點擊查看大圖"class="illustration_alink">/iknow-pic.cdn.bcebos.com/359b033b5bb5c9eaa7e2a10ddb39b6003bf3b3cf?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/359b033b5bb5c9eaa7e2a10ddb39b6003bf3b3cf"/>
4、選擇窗口中的文件進行轉換成，此處文件是需要轉換成pdf格式的界面。
/iknow-pic.cdn.bcebos.com/0823dd54564e92582e7224009282d158cdbf4e9e"target="_blank"title="點擊查看大圖"class="illustration_alink">/iknow-pic.cdn.bcebos.com/0823dd54564e92582e7224009282d158cdbf4e9e?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/0823dd54564e92582e7224009282d158cdbf4e9e"/>
5、按回車鍵，又會出現對話框，此時選擇需要保存的文件位置，點擊確定即可。
/iknow-pic.cdn.bcebos.com/b17eca8065380cd755d00003af44ad3458828116"target="_blank"title="點擊查看大圖"class="illustration_alink">/iknow-pic.cdn.bcebos.com/b17eca8065380cd755d00003af44ad3458828116?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/b17eca8065380cd755d00003af44ad3458828116"/>
6、此時電腦就會自動打開轉換成pdf格式的文件。
