NoirArchitects.Ncored 2026.2.4

Fast PDF viewer for large construction drawings

Ncored is a fast desktop PDF viewer and markup tool built specifically for architects, structural engineers, mechanical and electrical engineers, BIM coordinators, and construction managers who open very large (50 to 220 MB) construction drawing PDFs every day. The product is intentionally narrower in scope than general-purpose PDF suites. The focus is the specific moment a professional opens a heavy construction drawing exported from ArchiCAD, Revit, AutoCAD, Vectorworks, or SketchUp Layout, and needs to scroll, zoom, mark up, and search it without the freezes that typically occur in general-purpose PDF tools. Markup and annotation tools produce standards-compliant PDF output that survives in any conforming PDF viewer. Includes in-place text editing, image cleanup, full-text search across hundreds of pages, and configurable PDF compression.
