AutoCAD is a 2D drafting software. It is a commercial-aided design and drafting software. It is developed by Autodesk. It is a multi-field software which is used by all professionals such as Interior Designers, Civil Engineers, Architects, and Mechanical engineers. It’s a starting point of architectural, civil, mechanical even electrical designing. That’s the reason why people want to learn AutoCAD.
There are various panels in ribbon panel of this drafting software which consist numerous tools and commands to create any drawing easily. One such panel is Modify panel.
