Understanding Vector vs Raster PDFs: When You Need AI Vectorize
Vector vs Raster PDFs
- Most CAD professionals waste thousands of dollars using incorrect conversion methods for different PDF types.
- Vector PDFs can be converted for free in AutoCAD using the PDFIMPORT command; raster PDFs, on the other hand, require manual conversion or the use of AI tools.
- Quick test: Zoom to 400% - Vector text stays crisp, raster pixelates
- Manual tracing costs: $120-180 per sheet (estimated) vs $45-50 with AI Vectorize
- Understanding this difference saves weeks of project time and conversion costs
The Critical Knowledge Gap Costing AEC Firms Thousands
Take a look at the PDF on your screen right now. Can you tell if it contains editable vector data or if it's just a picture of a drawing? If you can't answer that question in 10 seconds, you're possibly wasting thousands of dollars on unnecessary conversion services.
Many people assume all PDFs are identical. But some contain rich vector data that converts instantly in AutoCAD. In contrast, others are essentially photographs that require specialized AI tools. Understanding this difference can save your firm thousands of dollars and weeks of project time.
"I'll have to admit, I'm impressed with HP AI Vectorize software. I'll give it a grade of 95. It is something that I can use."
— Tim, Structural Engineer
Vector PDFs: The Files That Convert for Free
When you export a drawing from AutoCAD, Revit, or MicroStation to PDF, you're creating a vector PDF. These files retain the original geometric intelligence. Vector files contain actual line data with mathematical properties that CAD software can read and reconstruct.
Calculate Your ROI with HP AI Vectorize
Still redrawing scans manually? HP’s AI Vectorize automates the process, instantly converting scanned drawings into editable CAD files with layers and text.
Use our free ROI calculator to estimate how much time, labor, and budget your team could reclaim by letting AI do the heavy lifting.
✅ Check the Numbers
Think of it this way: A vector PDF is like a compressed CAD file that can be "unzipped" back to its original editable state.
Quick Identification of Vector PDF:
- Text remains selectable when you click on it
- Lines stay crisp at any zoom level
- File properties show "Creator: AutoCAD" or similar CAD software
Converting Vector PDFs:
- Import your PDF into AutoCAD, BricsCAD, or DraftSight
- Use the built-in PDFIMPORT command
- Generate a clean, layered CAD file in seconds

Critical insight: If you have vector PDFs, you never need AI Vectorize. Your CAD software already has everything it needs.
Raster PDFs: The Expensive Problem
Raster PDFs are fundamentally different. Rasters are digital photographs of drawings with zero geometric intelligence. These files come from scanning physical blueprints or legacy drawings.
The costly reality: Once converted to a raster PDF, all the mathematical data that makes CAD powerful is lost. Ultimately, the geometry is gone and only pixels remain.
Raster images are created when you scan a physical sheet and save it as a PDF file.
Tips for Spotting Raster PDFs:
- Text appears blurry when zoomed in
- Lines pixelate at high magnification
- File properties may show the scanner manufacturer
When you try to convert a raster PDF using AutoCAD's import tools, the software has nothing to work with except pixels. It's like trying to extract a recipe from a photograph of a finished meal; the visual information is there, but the underlying data isn't.
The Raster Conversion Challenge
For years, AEC firms dealt with rasters in these ways:
Manual Tracing: Import raster PDFs as background images and manually redraw everything. This process consumes 4-8 hours per sheet and incurs hundreds of dollars in labor costs.
Overseas Outsourcing: Pay $125-175 per sheet with 1-3 week turnaround times, inconsistent quality, and communication barriers.
Legacy Software: Traditional scan-to-CAD tools, such as Scan2CAD and WiseImage have steep learning curves and deliver less-than-optimized output, and can struggle with converting text (OCR - Optical Character Recognition).
HP's AI Vectorize: Purpose-Built for Raster Conversion
HP's AI Vectorize software is part of their new Build Workspace platform and represents a significant advancement over manual tracing, utilizing machine learning specifically trained on architectural and engineering drawings.
AI Vectorize from HP uses the power of AI to convert flat images into workable CAD files.
The process is surprisingly simple:
- Upload raster files to HP Build Workspace (free account)
- Click "Vectorize" to start AI conversion
- Download production-ready DXF in minutes
What Makes It Different
Unlike generic OCR, HP's AI is trained explicitly on technical drawings and images. During development, the HP Dev Team processed over 5,000 architectural and engineering drawings to understand building symbols, dimension styles, and line conventions.
"AI Vectorize worked well, even if the image is somewhat blurry. It captured everything very well."
— Ben, Custom Windows & Doors
Innovative Features That Save Time
Intelligent object recognition: Proper identification of Doors, windows, and fixtures
Automatic layer organization: Sorts Elements into logical layers (doors, windows, text)
Text preservation: Dimensions and notes become editable text, not images
Built-in editing tools: Make adjustments before downloading (included free)
Convert raster images to CAD-ready vector files in minutes. Layers are automatic.
The Economics Make Sense
*Quality ratings based on typical industry experience
