Parent page: Version Control and Design Repositories
The best way of working from a known set of source files is to store the design project in a controlled environment, such as a Version Control repository. This is important because the only way of ensuring the outputs come from the correct source files is to:
In Altium NEXUS, such a repository is referred to as a Design Repository. Owned by the design team, the Design Repository contains a high-resolution view of the history of the design process and is the primary collaboration tool used by the design team.
The Design Repository becomes the central repository from which multiple team members can check data in and out, all the while maintaining a complete revision history of all changes made to the design. A design is therefore stored as a series of versions of its constituent project and source documents, building a progressive picture of the intent of a designer over time. By using a version-controlled Design Repository, you have the integral assurance that no revision of a design is ever lost, allowing for safe collaboration on the same design between members of a team that can be geographically dispersed in their locations. The very nature of the version control system provides an audit trail for the design. Full accountability arises through transparency of whom changed what, in which source document, and when. The system can support multiple version-controlled Design Repositories with the link to a particular repository being established by the version control link within the project folder.
The version control software - used to implement the repositories themselves - is supported in the following ways:
For each registered, or rather connected repository, the following information is presented:
SVN. For the integrated repository provided through your managed content server for managed projects, this is Git. For a repository defined through your managed content server's local Version Control service, this is SVN or Git.
Creation of new Design Repositories from within Altium NEXUS is performed from the Data Management - Design Repositories page of the Preferences dialog. Click the button and choose SVN from the associated drop-down menu. The Create SVN Design Repository dialog will appear. Use this to give the repository a meaningful name, specify a default checkout path, and specify the location for the repository. If a folder is specified that does not currently exist, it will be created for you.
With all settings specified as required, click OK. The repository will be created at the nominated location and a connection to that repository from Altium NEXUS made. An entry will appear for it in the listing of Design Repositories back on the Data Management - Design Repositories page of the Preferences dialog.

When using an Altium NEXUS Server as your managed content server, SVN repositories can be created through the Server's local Version Control service, or external repositories (SVN or Git) can be connected to. Together, all repositories are centrally managed through the VCS page (Admin - VCS) of the Server's browser-based interface.
The properties required depend on whether you are creating a new repository using the local VCS service, or linking to an existing, external repository:
A linked, external Design Repository is distinguished in the list of repositories by its External property being ticked (). The list of repositories is automatically sorted alphabetically by Name, with repositories defined through the Version Control service listed first, and then external repositories thereafter. The Git-based Versioned Storage repository always appears at the top of the list.
Design Repositories defined through the Altium NEXUS Server are populated to the client automatically during sign-in, so users do not have to worry about urls, protocols, passwords etc. A repository is configured once, on the server, and shared with the intended users as required.
In a collaborative environment, one or more Design Repositories may already have been created in a location accessible by multiple users. In this case, you do not need to create a new repository - re-inventing the wheel as it were - rather you simply need to connect to the required existing repository. This is also the case if you have removed a repository from your list of repositories, and want to add it back in again.
To connect to an existing repository, click on the button and choose SVN from the associated drop-down menu. The SVN Design Repository dialog will appear. Enter a name by which to refer to the repository from within Altium NEXUS, specify a default checkout path, and specify the repository access method and path to the root folder of the repository. You can also specify a particular sub-folder within the repository.
With all settings specified as required, click OK - a connection will be made and the repository will be ready for use.
The Data Management - Design Repositories page of the Preferences dialog offers no controls for creating a new Git repository, or connecting to an existing one. However, you can effectively connect to an existing repository of this type by other means - means which are the traditional technique favored by the Git usership. To do so:
Altium NEXUS will recognize that the project is under version control in a Git-based repository, and provide VCS-related statuses, and commands/ functions to work with the files (including Commit (to local working Git repository) and Push (from local Git repository to remote Git repository)).
You can also edit the properties of a Design Repository at any time. For example, you might want to change the name of the repository, as displayed and referenced within Altium NEXUS. Or you might want to edit the connection, perhaps to link to a different repository. To do this, select the entry for the repository in the listing of repositories, then click on the button. The SVN Design Repository dialog (or Git Repository dialog) will appear, from where you can make changes as required.
To disconnect from a Design Repository, select its entry in the list and click the button. The repository is removed from the list of connected Design Repositories. The repository itself is not deleted, it simply becomes disconnected from the system. To use a repository again, connect to it.
Once defined, the connected nature of a VCS-based Design Repository simplifies the ability to either add a project to that repository, or open an existing project from that repository. Instead of having to remember the path or drill down in a browse menu to select the repository, you simply choose the required repository from a convenient listing of all Design Repositories you are currently connected to, and that are activated for use.
Adding a Regular design project to a Design Repository is a straightforward process. With the project open, use the Add Project Folder To Version Control command from either the Projects panel or Storage Manager panel. The Add to Version Control dialog will appear. The field at the top of this dialog presents a drop-down listing of all connected and activated Design Repositories. Select the repository required.
The folder hierarchy within the chosen Design Repository is presented to you in the Folders region of the dialog. Either specify an existing folder into which to add the design files, or create a new folder using the New Folder button. In the latter case, a folder will be added at the specified position within the repository's folder hierarchy, named after the source folder containing the project.
When creating a new VCS project, the Repository field in the New Project dialog presents a drop-down listing of all connected and activated Design Repositories. Select the repository required.
Related page: The Managed Project
Whether creating a new managed project, or converting an existing design project (Regular or VCS) to a managed project, the resulting project is stored in a Design Repository. As part of the respective interface used to create/convert, the repository can quickly be selected from a list of defined repositories.
Equally straightforward is the ability to open a VCS design project that resides in a Design Repository. Use the File » Checkout command - the Check Out dialog will appear. Use the Check out from field to choose the required repository from a drop-down listing of all connected and activated Design Repositories.
The folder hierarchy within the chosen Design Repository is presented to you in the Folders region of the dialog. Use this region to specify the exact folder that is to be checked out from the repository.
Use the Check out to field to specify where the nominated folder content is to be checked out to. This is your local sandbox area.
To work on a managed project - essentially checking out as a local working copy - use the File » Open Managed Project command. The Open Managed Project dialog will appear, from where you can choose which managed project to open. Only those Managed Projects that have been shared with you (you have permission to access) will be listed, from the Versioned Storage design repository, and any other SVN or Git design repositories shared with you (when using an Altium NEXUS Server).
