About Copying a Single Region to WORD
Use any technique to copy a single worksheet region to the clipboard.
When you paste the clipboard into a WORD document:
A text region is pasted as flowing text, with inline math regions aligned to the text’s baseline. Use Merge Formatting to remove text style.
A non-text region is pasted as an image without an RTF box. The image size is set according to the zoom level of the Mathcad worksheet.
