Managing revisions and editing drawing details

Constructable keeps revisions together under one logical drawing, so the Drawings page can show the latest published version without losing history.

Constructable keeps revisions together under one logical drawing, so the Drawings page can show the latest published version without losing history.

Best for: Drawing administrators and anyone checking history · Outcome: Choose the right revision and avoid breaking its identity.

How a new revision is created

When a confirmed sheet matches an existing drawing, publishing it adds a revision instead of creating another unrelated row. Sheet number consistency is the most important part of this match.

When a new revision is confirmed, Constructable can copy scale information and non-takeoff markup from the latest published revision. Copying occurs only when the new revision does not already contain markup; takeoff marks are not carried forward. Always review the new sheet before assuming copied markup still points to the right location.

In the ASI 3 example, the newly published A101 becomes the current drawing. The previous A101 remains available as an older revision for comparison and historical context.

View revision history

Open a sheet in the viewer and use the revision selector to switch versions. If you open an older revision, a notice points you back to the latest version.

You can also open revisions in a new tab, compare them in Split View, or use an overlay. See Comparing sheets and revisions with Split View and Comparing drawings with overlays.

On mobile, revision labels may use the compact form V1, V2, and so on instead of Rev. 1, Rev. 2. They refer to the same revision history.

Edit details shared by all revisions

Use Edit Drawing Details when correcting information that identifies the drawing:

  • Sheet number
  • Sheet title
  • Discipline
  • Drawing tags

Changes to sheet number, title, or discipline apply across the drawing's revisions. Renaming a sheet to a number already in use can create a conflict or merge situation, so review the destination carefully.

Edit one revision

Revision-specific details, such as the sheet date, can be changed without rewriting the full drawing history. From a drawing set, you can edit selected or all sheet dates in bulk.

Use revision-level editing when the title block changed for one issuance but the overall drawing identity did not.

Delete carefully

Deleting a published revision can cause the remaining revisions to be renumbered. Deleting an entire drawing set can affect many drawings at once.

Use this decision guide:

  • Edit details when the drawing or revision metadata is wrong.
  • Unpublish when a released revision should temporarily disappear from current drawings.
  • Upload a new revision when issuing a correction that should remain part of the history.
  • Delete only when the page should no longer be part of the active record.
