How to Export True Vector Drawings from AutoCAD and Revit for Electrical Estimating

Once a contractor understands the difference between vector and raster drawings — and why it matters for auto-count — the natural next step is asking the right person for the right file. That usually means contacting the engineer or designer and asking for a vector PDF of the electrical drawings. It sounds simple. In practice, it is often not.

The problem is that most contractors do not know exactly what to ask for. “Can you send me the PDF as a vector?” lands differently than it should, because a lot of engineers and designers don’t immediately know how to respond to that either. They know how to export drawings.

They may not know which export settings produce a true vector output versus a raster output dressed up as a PDF. The result is that you ask for a vector file, they send you something that looks like a proper PDF, and you load it into your auto-count software only to discover it’s a raster image all over again.

This is a fixable problem. If you know exactly what settings produce a true vector PDF — from both AutoCAD and Revit — you can tell the engineer exactly what to do. Better yet, if you have access to the original CAD or Revit files, you can export them correctly yourself. Either way, you stop guessing and start controlling the quality of your drawing input before the takeoff begins.

Here is exactly how to do it — step by step, in plain language — for both platforms.

How to Export a True Vector PDF from AutoCAD

AutoCAD’s default PDF export settings do not always produce a true vector output. The key is in the PDF options, specifically the vector quality setting. Follow these steps exactly:

1. Open your drawing and go to PLOT (or press Ctrl + P on your keyboard) to open the plot dialog
2. Set the printer/plotter to a PDF generator — specifically, select AutoCAD PDF — General Documentation .pc3 from the printer dropdown. This is the plotter configuration file that supports full vector output
3. Click PDF Options in the plot dialog. This opens the PDF-specific settings panel
4. Set Vector Quality to 1200 dpi or higher. This is the critical setting. A lower vector quality setting compresses geometry and can cause the output to be treated as raster by other software. 1200 dpi preserves full geometric precision
5. Make sure “Include layer information” is checked. This keeps the vector paths organized by layer, which makes symbol identification more reliable in auto-count tools

Why each step matters: the plotter configuration determines the output engine AutoCAD uses. The vector quality setting determines how precisely the geometry is encoded. Layer information keeps symbols organized and distinguishable. Skipping any of these steps — particularly the vector quality setting — can result in a file that looks like a vector PDF but behaves like a raster image in auto-count software.

How to Export a True Vector PDF from Revit

Revit’s PDF export process is different from AutoCAD’s, and the most important setting is one that most users miss entirely. Here is the correct sequence:

6. Go to File > Export > PDF in the Revit menu
7. In the Export dialog, open the Export Setup settings menu — this is where the critical options live
8. Change Hidden Line Views from Raster Processing to Vector Processing. This is the setting that most people miss and that makes all the difference. Without this change, Revit renders hidden line views — which includes most electrical plan views — as raster images embedded in the PDF, even though the rest of the file may be vector
9. Set Raster Quality to Presentation. Some drawing elements — logos, photos, and image-based objects embedded in the Revit model — cannot be exported as vector. This setting controls how those unavoidable raster elements are handled. Presentation quality ensures they render cleanly without degrading the rest of the drawing
10. Click Export and save your file

The Hidden Line Views setting is the one that wins or loses this process for most Revit users. Electrical plans rely heavily on hidden line rendering. If that view type is processed as raster, your entire electrical plan sheet comes out as a raster image — even if every other sheet in the set exports correctly as vector. Change that one setting and you eliminate the problem.

What to Do When You Can’t Get Vector Drawings

Sometimes you have no control over what arrives in your inbox. Scanned legacy drawings from a 1980s project. Old field-marked sets from a renovation bid.

Drawing packages from an engineer who only has paper originals. In those cases, you cannot ask for a vector export because there is no vector source to export from. You are working with raster — and you need to know that going in.

Standard auto-count tools are not built for raster drawings. They will struggle with pixel-level symbol matching, orientation variation, and scan artifacts. The time cost of manual correction usually exceeds the benefit of attempting auto-count at all.

This is precisely the problem that Best Bid’s hybrid AI Auto Count tool was built to solve. It is designed to work on scanned drawings, recognizes symbols across different orientations, and handles the kind of drawing quality that standard template-matching and library models cannot manage reliably. When you cannot control the source, use the right tool for the job.

Ask the Right Questions Before You Start the Takeoff

Build this habit into every takeoff before you touch the auto-count tool. Ask yourself three questions:

• Are these drawings vector or raster? (Run the zoom test and the text test from Post 6 if you are not sure)
• Did I export these myself with the correct settings, or did I receive them from an outside source without knowing how they were produced?
• If they are raster, do I have the right tool for the job — or am I about to spend two hours fighting software that was never designed for this drawing type?

Two minutes of pre-check before every takeoff saves hours of frustration. Know your drawing type. Know your tool. Control what you can control — and when you cannot, use a tool that was built for the reality you are working in.
