Archi Check
Archi Check is specialized software designed specifically for quality control in architectural drawing sets, offering a more streamlined alternative to comprehensive PDF tools and complex BIM systems. It operates on a straightforward loop: Check, Correct, Verify, and Close. Each markup is transformed into a unique comment that is tracked with an ID, an assignee, and its current status, ensuring a thorough audit trail for every markup, feedback, assignment, and status update. The interface features a dual-screen setup, displaying the drawing in full size on one screen while the comment register occupies the other. Users can utilize various markup tools such as pins, rectangles, revision clouds, arrows, highlights, freehand drawing, text, callouts, and status stamps. The software includes five distinct role-based permissions to maintain clarity in responsibilities. Additionally, all quality control data is securely stored within your project folders on platforms like OneDrive, SharePoint, or local networks, without any synchronization to the cloud for comments, and it remains fully operational offline. Furthermore, non-destructive exports allow users to generate marked PDFs and registers in formats such as XLSX or CSV. Currently available for Windows, the software also offers macOS compatibility with the purchase. This versatility makes Archi Check a valuable asset for architectural professionals keen on maintaining high-quality standards in their projects.
