![]() Zones can have fillets (rounded corners) added in the Zone Properties dialog. Opening an old design in the latest version of KiCad. The new algorithm produces slightly different results from the old algorithm, so this settingĪllows the old behavior to be preserved to prevent producing different Gerber outputs when KiCad’s zone filling algorithm has been improved to give better results and faster performance. Manufactured board due to manufacturing tolerances. The default value typically results in arc approximation error that is not detectable in the Setting this to a lower number than theĭefault value of 0.005mm will result in smoother shapes, but can be very slow on larger boards. Segments and the true shape of the arc or circle. This approximation: in other words, the maximum distance between a point on one of these line This setting controls the maximum error allowed by Shapes such as those of arcs and circles. In some situations, KiCad must use a series of straight line segments to approximate round KiCad supports a separate size constraint for microvias as they typically can be smaller than Typically laser-drilled vias that connect an outer copper layer to the adjacent inner layer. This setting must be enabled before you can place microvias using the router. Buried vias are mechanically-drilled vias that start and end at This setting must be enabled before you can place blind or buried vias using the router.īlind vias are mechanically-drilled vias that start at one of the outer copper layers but endĪt one of the inner layers. In addition to setting minimum clearances, a number of features can be configured here: Setting If the schematic symbol is updated to specify a different footprint. If unchecked, footprints that are already in the PCB will not be changed, even Specified in the corresponding schematic symbol. If checked, footprints in the PCB will be replaced with the footprint that is Replace footprints with those specified in the schematic If unchecked, footprints without a corresponding symbol will not be deleted. If checked, any footprint in the PCB without a corresponding symbol in the Layout between identical channels of a design. Workflows that rely on changing the links between schematic symbols andįootprints, such as refactoring a schematic for easier layout or replicating This option should generally be left unchecked. Each footprint’s referenceĭesignator will be updated to match the reference designator of its linked Usual, rather than by reference designator. If unchecked, footprints and symbols will be linked by unique identifier as The same reference designator as the footprint. If checked, each footprint in the PCB will be re-linked to the symbol that has Re-link footprints to schematic symbols based on their reference designatorsįootprints are normally linked to schematic symbols via a unique identifierĬreated when the symbol is added to the schematic. The tool has several options to control its behavior. Shows or hides the Appearance and Selection Filter panels on the right side of the editor. Switches display of tracks between filled and outline mode. Switches display of vias between filled and outline mode. Switches display of pads between filled and outline mode. Net Tools menu, or right-click the net in the list in the Nets tab of the Appearance panel. The hotkey `, right-click any copper object in the net and choose Highlight Net from the ![]() Note: this button will be disabled when no net has been highlighted. When a net has been selected for highlighting, switches the highlighting on or off. The Hide mode can only beĪccessed via the controls in the Appearance Panel or via the hotkey Ctrl+ H. Pressing the button will change the layer display mode to Normal. Switches the non-active layer display mode between Normal and Dim.īe highlighted when the non-active layer display mode is either Dim or Hide. Switches between straight and curved ratsnest lines. Switches between full-screen and small editing cursor (crosshairs). Switch between polar and Cartesian coordinate display in the status bar.ĭisplay/entry of coordinates and dimensions in inches, mils, or millimeters. This behavior can be changed in the Display Options section of Preferences. Note: by default, hiding the grid will disable grid snapping. The left toolbar provides options to change the display of items in Pcbnew. ![]()
