Render and Annotate Blueprints
Fast render complicated blueprints and view all details by zooming in 1000%. Allow to make colored annotations and add personalized shapes to PDF documents.

Easily Measure Floorplan
Accurately measure any line, perimeter, area, and arc in floorplans, three-dimensional drawings, and sectional drawings.

Compare Altered Drawings
Compare original and altered PDF drawings side by side or overlay them with highlighted changes, ensuring construction runs swimmingly.

Sign PDF Documents
Effortlessly add digital or electronic signatures to contracts, bids for works, certificates of completion, etc.

Create QA/QC Forms
Enable engineers to create and fill the quality testing forms, inspection reports, and other checklists to guarantee engineering and life safety.

Effortless Layer Viewing & Switching
Effortlessly explore building structure, piping, electrical, fire protection, and other layers in your PDF architectural drawings with precision and clarity. View layer details and separately. Customize the layer properties for exporting or printing.

My project consists of building a project management web app and a mobile app to track and monitor work progress. With ComPDF SDK, users are able to view, edit, and measure drawings whether they are in the office or on the construction site.
