Apowersoft CAD Viewer: Open and Mark Up DWG Drawings Without AutoCAD
Apowersoft CAD Viewer is a $39.95 one-time Windows program that opens AutoCAD DWG drawings of any version, and lets you annotate them, measure them and convert them to PDF. It's for people who receive drawings, such as contractors, clients and estimators, and don't have an AutoCAD license.
If all you need is to look at a DWG, Autodesk's free DWG TrueView does that, so the $39.95 only pays off if you want the markup, measuring and editing tools.

We didn't install the program or open a drawing in it, so the features below come from Apowersoft's product page.
Before you buy
Test your own drawings first. Apowersoft shows no screenshots of the program on its page, and the last version we could find dates from 2021. Open your newest DWG files and your custom fonts in the trial before paying, and check that recent DWG versions open.
Know the vendor's record. Apowersoft scored 1.9 out of 5 on Trustpilot from 241 reviews on November 6, 2026, mostly over support, activation and refunds. A change of mind isn't covered by the refund policy.

Overview
Apowersoft CAD Viewer follows three steps: browse for a DWG file, open it, then view or change its contents. Apowersoft says you don't need CAD training to use it, and it aims the program at the people around a design, as much as the designers themselves.
Features
Apowersoft CAD Viewer opens DWG files of any version
Apowersoft CAD Viewer is built to open both higher and lower DWG versions. Apowersoft says it avoids common problems such as unclear fonts and garbled Latin characters, which is the usual reason people look for an alternative to an older viewer.
Apowersoft CAD Viewer annotates and dimensions drawings
Apowersoft CAD Viewer adds text, lines, ellipses and rectangles over a drawing, and linear, radial, angular, ordinate and arc-length dimensions. Your notes are saved in the drawing, so a colleague or client can see them when they open it.
Apowersoft CAD Viewer measures what's on the page
Apowersoft CAD Viewer measures distance, angle, radius, area, volume, arc length and coordinates. That's useful for pulling a quantity from a plan when you don't own the design software.
Apowersoft CAD Viewer converts DWG to PDF
Apowersoft CAD Viewer turns a DWG into a PDF without AutoCAD installed, so you can print it or send it to someone who has no CAD software at all.
Benefits
- No CAD license for the people who only need to read. A one-time $39.95 beats a seat of AutoCAD for occasional use.
- Comments that travel with the drawing. Your notes stay in the file rather than in a separate email.
- A small program. Apowersoft describes it as lightweight on disk space.
Real-World Uses
- A contractor on a job: open the architect's DWG, measure a wall run, and circle a clash with a note.
- A client reviewing plans: mark up changes and send the file back, or send a PDF to the rest of the family.
- An estimator: pull lengths and areas from a floor plan for a quote.
Who it's for, and who should skip it
It fits occasional users who receive DWG files and want to mark them up and measure them on a Windows PC. Skip it if you only need to look at or print a drawing, since DWG TrueView is free. Skip it if you draft for a living: this isn't a replacement for AutoCAD. A Mac user needs something else, and anyone who depends on current DWG support should test carefully, since the program looks unchanged for years.
Usage Guide
- Install and launch Apowersoft CAD Viewer. The download fetches the program during setup.
- Browse to your DWG file and import it.
- Open it and pan and zoom around the drawing.
- Use the annotation, dimension and measure tools as needed.
- Save your changes, or convert the drawing to PDF to print or share it.
Where it falls short
- No sign of recent updates. The latest version we could find is from 2021, while DWG files keep moving on.
- Limited documentation. We found no manual or how-to guide for it on Apowersoft's site, and no system requirements on its product page.
- No independent reviews. SourceForge shows no ratings, and we found no magazine or CAD site that has tested it, so its promise of accurate rendering is unverified.
- DWG focus. Apowersoft's page talks about DWG only, so don't assume it opens other CAD formats.
What Users Say
We found no independent reviews of Apowersoft CAD Viewer, so all we can offer is what Apowersoft publishes and the company's general record. It's a short section because that's all there is.
Apowersoft's page (vendor testimonials)
Johnson: "As a drafter, I always have problems when collaborating with others. This software helps me open higher DWG version successfully. Thank you so much!"
Barbosa: "Very very very good software. No lags when opening my files and it shows the details clearly and accurately."

Trustpilot (Apowersoft as a company)
On November 6, 2026 Apowersoft scored 1.9 out of 5 from 241 reviews, with 57% five-star and 35% one-star. We found none about CAD Viewer itself. The repeated complaints are about unanswered support emails, activation, unexpected charges and refunds.
Comparisons
Apowersoft CAD Viewer vs DWG TrueView
Autodesk's DWG TrueView is free and comes from the company behind the format, so it's the safe choice for viewing, measuring and printing. Apowersoft CAD Viewer's case rests on annotation, dimensions and basic edits saved into the drawing, which a viewer-only tool won't do.

Conclusion
Worth $39.95 only if you need markup and measuring. The one reason to buy Apowersoft CAD Viewer is cheap annotation, dimensioning and PDF output on DWG files without an AutoCAD license. The main reason not to is that it looks unmaintained, has no independent reviews and comes from a vendor with a poor support record. If you only need to view drawings, use the free DWG TrueView.
