With 3D Repo's Issue Tracking feature, you can share documents and web links with other users by adding them to existing issues. You can attach just about anything, most commonly people share PDFs, Images/Videos, URL links and Word/Excel documents.
Attachments work with existing issues only. You will have to create an issue first and then add resources to it. Here is where you can find it:
Open an existing issue and head over to the Attachments tab
Click on Add Resource
Add/Remove a File
In the Files tab, click to open a file or drag and drop it into the square box
You can edit the file name (displayed in 3D Repo)
To remove the file click on the grey Minus button
Click on the green Save button to upload them
Add/Remove a Link
In the Links tab, click on Add Link
Type a Resource title and paste the URL link
To remove it click on the grey Minus button
Click on the Save button
Open/Access a File
The new resources instantly appear in the Issue Attachments tab.
Here is how you can interact with them:
Keep adding as many resources as you want and/or delete them
Click on each resource to open it.
Quote a resource as a reference link which appears in the Comments section to share it in the conversation with other people.
