PDF Export

NullCad exports drafting sheets as a multi-page vector PDF — geometry is written as real vector paths (and text as glyph outlines), not a raster image, so the output stays crisp at any zoom and prints cleanly.

What gets exported

Each page proxy in the document becomes one PDF page:

1. Page content — geometry sharing the page’s phase and intersecting its bounds is transformed from world meters to paper millimeters at the page’s draw scale, styled per layer (color, line weight, line type), and clipped to the sheet.
2. Viewport content — geometry composed through any viewports on the page, from whichever phase each viewport targets, at that viewport’s own pan/zoom/rotation.
3. Sheet template — the assigned title block, rendered on top, with its substitutable fields (<PROJECT>, sheet number/name, etc.) filled in.

Pages are ordered by (sheet number, name), so legacy documents (where every sheet number is 0) keep their existing name order.

Exporting

Open the PDF export dialog from the Sheet Manager or File ▸ Export ▸ PDF. You can choose which pages to include and export options such as monochrome output.

Line types in the exported PDF

Custom linetype patterns (dashes, dots, center lines, etc.) are resolved against the project’s linetype library and interpreted as paper millimeters, independent of the page’s draw scale — so a dash pattern defined for a 1:500 sheet looks the same physical size as the same pattern on a 1:100 sheet.

Text

Text is rendered as filled glyph outlines rather than PDF text objects, so the exported PDF doesn’t depend on font availability on the viewer’s system and renders identically everywhere.
