A drawing review often starts with a file created by someone else: a PDF from a supplier, a DWG from an engineer, a DWF plot, or a scanned document. The job may not be to edit the original CAD model. It may be to confirm that the drawing is readable, check a few dimensions, record comments and send a clear copy to the next person.
That sounds simple, but the work can become fragmented. One program opens the drawing, another adds comments, and a third produces the print or PDF. A repeatable review process helps keep those steps together and makes it easier to see what was checked.
1. Start by identifying the file and the task
Before opening a drawing, establish what the recipient needs to do with it. Is the goal to inspect a revision, verify a dimension, add review notes, print a paper copy, or prepare a PDF for distribution?
The source format matters too. Technical teams may receive PDF, DWG, DXF, DWF, PLT, HPGL/2, CGM, TIFF, CALS, Gerber and other formats. A viewer that handles several of the formats used by your team can reduce the number of format-specific handoffs.
Check the capabilities of the edition you use. ViewCompanion is available in Standard, Pro and Premium, and supported formats vary by edition. The ViewCompanion format support page lists format availability by edition.
2. Inspect at a useful scale
Start with the whole sheet to check its title block, revision, sheet number and general layout. Then zoom into the areas that need attention. Look for missing content, clipped notes, hard-to-read line work, unexpected page orientation and differences between sheets in a multi-page document.
If you need to measure, first confirm the drawing scale or calibrate against a known dimension. This is especially important when a file has been exported, scanned, or created with uncertain drawing units. A measurement tool can report precisely, but the result is only meaningful when the scale information is correct. Verify it against a dimension you already trust before using measurements for a decision.
3. Record review comments separately from the source
Review notes should make the requested action clear: identify the location, describe the issue, and state what needs checking. Use annotations such as text, symbols, stamps, lines or dimensions where they help point to a specific area.
Keeping markups in a review copy makes it easier to preserve the source drawing and share comments with colleagues. It also gives the next reviewer a visible record of what was checked. When preparing the copy, use a clear file name or revision label so it is not mistaken for the unmarked source.
4. Compare revisions when the question is “what changed?”
When two revisions are available, reviewing them side by side or using a drawing comparison tool can help focus attention on changed areas. Check the title block and revision identifiers as well: a visual difference alone does not tell you whether the correct files were selected or whether the change has been approved.
Comparison is a review aid, not a substitute for engineering sign-off. Confirm important changes against the revision notes and the project’s normal approval process.
5. Prepare a consistent file for distribution
Once review is complete, consider how the next person will use the result. A PDF is often convenient for sharing and printing. Check page size, orientation, line weights and legibility before sending it. If the review includes several source files, combining them into a single multipage document can make the handoff easier to follow.
For recurring work, batch printing or conversion can help apply the same output process to multiple files. Keep a copy of the source files and review notes according to your document-control practices.
6. Make the process repeatable
A short checklist can improve consistency across reviewers:
- Confirm the file name, revision and sheet count.
- Check the whole page, then inspect the areas relevant to the task.
- Verify scale before relying on measurements.
- Add comments that identify both the location and the requested action.
- Compare revisions when the review is about changes.
- Check the final PDF or printed pages before distribution.
- Preserve the source and label the reviewed copy clearly.
Using ViewCompanion for this workflow
ViewCompanion is a Windows application for viewing, printing, annotating, measuring and converting technical documents. The Standard, Pro and Premium editions support different sets of formats and tools. Premium adds DWG support and advanced PDF capabilities; you can review its features and supported workflows before choosing an edition.
The best way to check whether an application fits a team’s review process is to try it with representative files, including the files that are hardest to open, measure or print. Confirm that the output matches your requirements before using it in a production workflow.
