1. I can add a signature by inserting a picture directly into a CAD drawing. First click Insert in the open CAD drawing, and then click Image Reference.
2. Find the CAD signature picture we made to be inserted, and then click "Open". Click OK in the displayed figure to start.
3. Select the first point in the CAD drawing to add signature, and then click the left key to confirm. Then enter the specified scale factor or confirm by pulling the box.
4. After inserting, we left-click to select the graph, and then click "Place behind the object" in the modification tool. Click Modify-Object-Image-Border in the menu bar to add the signature to the CAD drawing. After the completion of a preview, you can see the final signature effect!
2. Use software, such as Peng's signature software, to sign electronically directly on it.
