Step 1: Know How “Save As PDF” Works
-
Go to File > Save As > (*.pdf).
-
SOLIDWORKS converts the drawing into plain vector lines.
-
SOLIDWORKS uses its internal proprietary code to generate the PDF.
-
This method does not rely on third-party software—the PDF output comes directly from SOLIDWORKS.
Step 2: Know How “Print to PDF” Works
-
Go to File > Print > (Choose a PDF writer).
-
SOLIDWORKS uses its print engine to spool the drawing.
-
The information is sent to your selected PDF writer or virtual printer
(e.g. Microsoft Print to PDF).
Step 3: Compare Both Methods Using an Original Drawing
-
Start with a standard SOLIDWORKS drawing.
-
Note the paper color and default appearance.
-
(Optional) To change sheet paper color:
Tools > Options > System Options > Colors > Color Scheme Settings > Drawings > Paper Color.
Step 4: Produce a PDF Using “Save As PDF”
-
Go to File > Save As > PDF.
-
Use default PDF options (unless you need changes).
-
Generate the PDF and review the output.
Step 5: Produce a PDF Using “Print to PDF”
-
Go to File > Print.
-
Select a PDF writer.
-
Print to generate the PDF.
Step 6 : Compare the Results
Line Quality
-
Print to PDF often causes lines to overextend, especially in detailed drawings.
-
Save As PDF generally avoids this issue.
Rebuilding Behavior
-
Automated PDF tasks/macros typically use Save As PDF.
-
When used in team environments:
-
Save As PDF forces a rebuild before generating the PDF.
-
If the model changes after the drawing is finished (but before the macro runs), these changes will appear in the PDF.
-
This can cause unintentional or unwanted updates in released documents.
