Every pad in the design and its connected copper will be listed as a net. Pads that do not have a net assigned will be assigned a system-generated net name. Use this to resolve errors in footprints that have copper touching pads, but those pads are not used in the current design. Refer to the Configure Physical Nets dialog page for more information. This command is used to re-synchronize the net name of the routing primitives to the net name on the pads to which those primitives connect.
After launching the command, a confirmation dialog appears asking whether you want to update free primitive nets from the component-pad nets. After clicking Yes , starting from each pad, the connected copper is selected and the net name of each routing primitive is set to match that of the pad to which it connects.
This command is useful after renaming a net in the schematic and updating the change to the PCB since the update process will only update the net names for the pads in the net. It can also be used to assign net names to extra copper added into a footprint. I have the same issue with Altium I have created a footprint in the same way as author of this topic by Altium recommendations and using it. Some of the footprints of the same type causes short circuit but other don't.
The way I got rid away these problems is to open a footprint in PCBlib editor, change it in some minor way for example move some copper by 0. And no further violations appears. It seems a software bug for me. One more thing is to keep dimensions of the pad as small as possible with respect to copper region, otherwise custom pad shape will not be recognized as pad. I am using a round shaped pad of 0.
Definitely agree there's a bug here, I can use the same process within the same footprint for multiple pads, when placed on a PCB some pads error, some don't.
A non-core change in the library and an "update footprint" usually clears the issue. Professional Electron Wrangler. Any comments, or points of view expressed, are my own and not endorsed , induced or compensated by my employer s.
By default, each component that fails to match is automatically included in the update. Control, as is the norm in Altium Designer, is always yours, and you may choose to exclude any non-matching components from the update process. The lower region of the dialog lists the differences found between primitives for the currently selected and non-matching component entry in the region above. The report provides:. Use the Engineering Change Order dialog that opens to validate then execute the updates accordingly.
Disable any changes that you do not want to occur. The changes will be made and the components that are included in the update will have their footprints updated to those in the source libraries. Direct update of placed schematic components and PCB footprints can be performed from within a source schematic or PCB library.
PcbLib libraries and where those libraries are made part of the available libraries for the project. Modifications made to components in a source schematic library are passed to the schematic document s using the Update Schematics command available from the Schematic Library Editor's main Tools menu. Alternatively, changes to selected components can be applied by selecting those components in the SCH Library panel and using the update command from the right-click menu.
All instances of the placed component s in all open schematic documents will be updated regardless of the project to which a document belongs. Essentially, if a placed component has the same entry for its Physical Component field as that of the library component, it will be updated. You will be notified as to how many components in how many documents have been modified by the update process.
The update is a full replacement of each existing component instance with that in the library. In much the same way, changes made to one or more component footprints in a source PCB library can be passed directly to placed instances of those footprints on the PCB. These commands can also be accessed from the PCB Library panel's right-click menu.
All instance of the placed component footprint s in all open PCB documents will be updated regardless of parent project. Essentially, if a placed component footprint has the same name as that of the library component, it will be updated. After updating the placed schematic components, schematic library components, or PCB Footprints, you will of course want to verify that the update proceeded as planned.
The following sections look at how you can quickly check that parameters, model links, and graphical attributes have updated successfully. You can check that the parameters have been updated correctly either by running the Parameter Manager Tools » Parameter Manager or by interrogating the parameters for a component in its associated properties dialog.
Below, the component C1 had the value of its DatasheetDocument parameter changed to Nov as part of an update process. Updates to model links for a component can be verified from the Models region of the associated Properties panel. The easiest way to check graphical updates is to compare the design component on the sheet against the component in the source library.
The latter can easily be displayed using the Libraries panel, which allows direct side-by-side comparison. Using Altium Documentation.
Now reading version You have placed components on the schematic, maybe even fully wired, compiled, and taken the design to the board layout stage.
More than likely, there will come a time when a change to a component is required - a new parameter added, a change to a model link, or maybe a change to a symbol or footprint at the graphical-level. You will need to launch the command again. If a component instance on a schematic has been placed from an integrated library IntLib or database library DBLib, SVNDBLib , using this command fully replaces the component and therefore the original library link will be replaced by a link back to the source library involved in the update.
This can be especially dangerous for a component placed from a database, as the link to the corresponding record in that database will be severed. It is therefore advisable and perhaps safer to use the Update From Libraries command. Printer-friendly version. Found an issue with this document?

Update will cause no change. This command is used for converting a Polygon Pour object back to its original set of primitive parts. After launching the command, the cursor will change to a cross-hair and you will enter polygon pour explode mode. Position the cursor over the polygon pour you wish to explode then click or press Enter.
The polygon pour will revert to the various primitives from which it was made. Continue converting further polygon pours to their free primitives or right-click or press Esc to exit polygon pour explode mode.
This command is used to convert one or more Polygon Pour objects back to their original sets of primitive parts. Each polygon pour will revert to the various primitives from which it was made. This command is used to add new primitive design objects to a Component object when graphically modifying the shape of the component directly within the PCB Editor.
First, place new primitives as required in the workspace then select these new primitives and launch the command. The cursor will change to a cross-hair and you will be prompted to choose a component. Position the cursor over the component that you want to add the selected primitives to and click or press Enter. A confirmation dialog will appear asking whether you wish to go ahead and add the selected primitives to the component.
Clicking YES will mean that the new primitives will be recognized as part of the single component object and may be used in conjunction with the component's original primitives to edit the shape of the component as required. This command is used for converting a Board Region object back to its original set of primitive parts. After launching the command, the cursor will change to a cross-hair and you will enter board region explode mode.
Position the cursor over the board region you wish to explode then click or press Enter.
