Hi Andreas Well very good it appears you are getting the hang of things. Don't forget to provide enough clearance between your shape and your clines (traces) & component pins. You can also do things like add voids to shapes to make things a bit neater and provide more clearance. Here is an example of a shape ( gnd ) with voids added. The component pins are connected manually because it was neater than doing a system wide dynamic tie in. You can see the components R1, C1, R3 connected into ground. In the area around these components there is a shape void. Look at the menu item "Shape > Manual void cavity" to do something like you see in the picture if that is what you are after. Notice around J3 the pink line. That is the outline of the void which is carving up the plane. Also as I mentioned above you want to have enough clearance between your shapes - Traces - Pins so that the dynamic shape does not flood to close, 25 mil or more clearance is a good starting value. On the bottom of my board there is also another ground plane. The vias next to the components tie both planes together. The shape editor in allegro is very very good, lots of possibilities exist. You can even do logos ! hope this info helps you out. All the best Paul![]()
