Version history: view, name, mark as current and delete
The Version control panel lists every version of a drawing and lets you open, compare, edit, mark as current or delete each one.

How to complete version control
- 01
Open the panel
Click Versiones (Versions) in the viewer header.

- 02
Read each row
Version number, thumbnail, version name (the date if it has none), notes, date and who uploaded it. Tags: Actual (current) and Viendo (the one you have open).

- 03
Open a version
Click Ver (View). The one you already have open says Abierta (Open).

- 04
Read-only mode
On an earlier version, an amber banner says it is read-only, with the link Volver a la versión actual (Back to current version).

- 05
Switch version quickly
Without opening the panel: the version button at the bottom right lists the versions, plus Choose version to compare and Open version control.

- 06
Compare
Comparar overlays that version on the one you are viewing (see the comparison guide).

- 07
Edit name and notes
The pencil opens the version name (for example «Issued for construction») and notes on what changed. Click Guardar.

- 08
Mark as current
Marcar como actual, on a version that isn't current, asks for confirmation. The current one moves to the history.

- 09
Delete a version
The bin asks for confirmation. If you delete the one you were viewing, the viewer takes you to the current version.
