Construction drawing control

Controlled drawings for live construction projects.

Topdraw gives the Project Manager one place to control who sends drawings, who receives them, and which revision everyone should be working from.

The core concept

Three roles. Clear responsibilities.

01

Project Manager

Creates the project, invites the team, controls drawing access, and tracks who has opened the latest revision.

02

Senders

Architects, engineers, designers, consultants, or suppliers who upload drawings and revisions.

03

Receivers

Site teams, contractors, clients, or consultants who view the drawings assigned to them.

Revision handling

Every new revision supersedes the previous one.

Topdraw keeps the revision history, marks the latest revision as current, and lets the Project Manager see who has opened it.

Drawing annotations

Add drawing markups when the team needs extra clarity.

Topdraw includes a browser-based annotation layer for drawing communication. Project Managers can add notes, arrows, shapes, and clouded areas to a revision without replacing the original PDF.

PM controlledOnly Project Managers can add or edit annotations, so the marked up drawing stays controlled.
Useful for drawing queriesUse annotations to point out a specific detail, raise a site query, or explain what needs checking.
Visible to the teamSenders and receivers can view the annotated PDF when the Project Manager needs everyone to see the markup.
Clean original keptThe uploaded drawing file is preserved separately from the annotation layer.
