As a result, the dimension becomes associated with the object and gets edited and deleted with the object. The Grids menu allows you to refine the grid settings to suit your routing requirements. Edit Vertex: Some of the same settings are available in this tab, but these will pertain to when a routed trace is being edited as opposed to initially routed. Some of the settings include whether or not the routing will shove other traces and/or vias aside and how much priority is given to the shoving. This command opens the "show element" form. Allegro X Design Platform | Cadence Design a simple board within 1 hour. Allegro Downloads | Cadence - Cadence Design Systems In typical PCB designs, various masks and surface finishes require verification of proper clearances and coverage. With Allegro PCB Designer you can easily generate reports about everything in your design from vias to Gerber. Before starting with PCB Design, you must have a completed schematic with no errors. These settings can be adjusted while you are routing on-the-fly, but here you can set up your default settings. To move an existing dimension to another class/subclass, use the Z- Move Dimensions command. Rigid-flex designs not only have the same mask and surface finish . Examples: Here is the real world example where ct will add a connect on top layer while the cb will add a connect on bottom layer funckey ct "add connect; class Etch ; subclass Top" Now that weve looked at some of the setups that you can use to customize your routing environment, lets next look at laying some traces down.
