1. First, we design our signature on a piece of white paper. Take photos and upload them to the computer.

2. open CAD. Take the 2007 version of CAD as an example. Insert the photo you just signed into CAD.

3. We enlarge the signature photo, select the multi-line tool on the left and draw a line along the bold edge of the signature photo.

4. Use this tool to draw a line along the bold edge. It doesn't matter if you make a mistake. You can also modify it later.

The same method will draw a line along the edge of bold words.

6. After filling in, we will move the font that has been drawn to the margin and fill it. A simple electronic signature is completed.
