Acrobatでpdf作成しました。図面の一部をコピーしパワーポイントに張り付けしようとしましたが出来ません。ソフトはacrobat standard dcです。

Hey!

You can copy content from a PDF unless the author has applied security settings that disallow copying. If you want to copy large content from a PDF, you can easily export the PDF to Word, Excel, or PowerPoint.

Upon copying the content, what exactly causing trouble. Would you mind elaborating your workflow step-by-step?

Specially, how you have been trying to attach it to PPT. Do you receive any error message?

How to copy the content from a PDF, for that you may refer to the steps suggested here: https://helpx.adobe.com/in/reader/using/copy-content-pdfs.html
