（1）菜单栏选择Add→3ptArc
3pt Arc的功能是先确定两个端点然后再往中心拉圆弧。主要是用在画2D线，在拼板时使用。
画的圆弧效果如下图所示
（2）带有圆心的圆弧
选择菜单栏Add→Arc w/Radius
画出的圆弧效果如下图所示

Allegro provides a good and interactive working interface and powerful functions, and its front-end products Cadence, OrCAD, Capture, the combination of high-speed, high-density, multi-layer complex PCB design routing provides the most perfect solution.
Allegro has perfect Constraint Settings, users only need to set the wiring rules according to the requirements, and the design requirements of the wiring can be achieved without violating the DRC when routing, thus saving the tedious manual inspection time and improving the work efficiency!
It can also define parameters such as minimum wire-width or wire-length to meet the needs of today's high-speed circuit board wiring.
Constraint Manger provides a simple interface for users to set and view Constraint declarations.
Its combination with Capture allows E.E. electronics engineers to set up regular data when drawing a circuit diagram and bring it with them to the Allegro working environment, where it can be automatically processed and checked when placing parts and wiring. The empirical values of these regular data can be reused for the same nature of the circuit board design.
In addition to the above functions, Allegro's powerful automatic push and stick line and perfect automatic repair line function provide users with great convenience;
The powerful mapping function can provide multiple users to deal with a complex board at the same time, thus greatly improving the work efficiency.
Or use the optional graph cutting function to cut the circuit board into various blocks, so that each block has a full-time person at the same time to design, to achieve the purpose of the same graph design and can shorten the time course.
After renaming, online interchange and modifying logic during routing, users can easily return to Capture wiring diagram, and update the wiring diagram to Allegro after modification.文章来源：https://www.toymoban.com/news/detail-545729.html
Users can also click and modify objects between Capture and Allegro.文章来源地址https://www.toymoban.com/news/detail-545729.html
