Scan your signature. It is best to use PS to change the graphics into bitmaps and save them in TIF format. Then open CAD and insert a raster image (you will find that the inserted signature becomes a white line), enter SPL (spline curve) at the command line, draw your signature as a hollow word with spline curve, and finally fill it in.

Computer-aided technical certification

Computer-aided design (CAD) refers to the use of computers and their graphic devices to help designers complete the design work.

In design, computers are usually used to calculate, analyze and compare many different schemes to determine the best scheme; All kinds of design information, whether digital, literal or graphic, can be stored in the internal memory or external memory of the computer and can be quickly retrieved; Designers usually start with sketches, and the heavy work of turning sketches into working drawings can be handed over to computers.
