Altium Designer Summer 09 in draw PCB appear collision Warning How to deal with it ？
This warning should mean that the original is too close , I've been there , It's like the software treats the cylinder as the square . My solution is this ： edit PCB original script , Place device body , Place the appropriate shape according to the shape of the original （ It could be a cylinder ）, It will be much better after editing the device body .
If you are sure that your drawing is OK , You can also ignore warnings directly ： Tools -> Reset error flag , Shortcut key ：T M, But this may not lead to errors .
Questioning ：
It would be nice if you could set and cancel this warning separately ~~~~
Chase and answer ：
Try this ： Design -> The rules ->Placement->ComponentClearance, Remove the tick


Powet Plane Connect（ Power layer connection type rules ）
The power layer connection type rule is used to set which pad type the component pin is connected to the power layer . The dialog box is shown in the figure 5-53 Shown .
This setting is mostly used in multilayer boards , It is mainly used to set the internal power supply and vias belonging to the power supply and ground network in the formation , And the connection mode between the pad and the copper foil .
stay Constraints（ Limit ） In the bar , There is a copper-clad model of the power supply layer . There is a drop-down list box in the upper left corner of the model , It is used to set the way in which the component pad is connected to the copper clad , Pictured 5-54 Shown .
Relief connections: Radial connection , That is to say, several wires protruding from the component pad are connected to the copper clad , In this way, the heat transfer between the copper clad area and the pad is relatively slow , During welding, it will not cause poor fusion between the pad and solder due to too fast heat dissipation in the copper clad area .
Direct connections: Direct connection , This connection directly covers the component pad with copper . The advantage of this connection is that the resistance between the pad and the copper-clad area is relatively small , But welding is troublesome .
No Connect: No connection mode , That is, there is no connection between the component and the power layer . This form is not generally used . If you choose Relief connections The way , You also need to set some parameters ：
1 Conductor Width: Set the width of the connector .
2 Conductors: Set the number of connecting lines . The alternatives are 2 Root and 4 root .
3 Air-Gap: Set the width of the air gap .
4 Expansion. Set the width between pads and holes .
Select the other two methods without setting these parameters .
In this case , We choose Relief connections（ Radial connection ） The way , Set up Conductor Width（ The width of the connecting line ） by 10mil,Conductors（ Number of connecting lines ） by 4 individual ,Air-Gap（ Air gap width ）,10mil,Expansion（ Width between pad and hole ） by 10mil.
