How can you classify the source?
Inspect one representative sheet at high zoom and test its content before promising editable CAD output.
| Signal | Likely type | Next step |
|---|---|---|
| Selectable geometry | Vector content | Test import |
| Pixel edges | Raster image | Plan redraw |
| Mixed content | Hybrid page | Separate workflows |
What does Autodesk confirm?
Autodesk distinguishes geometry and raster images in its PDF import controls. Raster images do not become editable linework through ordinary PDF import.

Common questions
What else should the bid team know?
Is every vector PDF an editable DWG?
No. Text, layers, blocks and precision may need rebuilding and checking.
Can a raster scan be redrawn?
Yes, when approved dimensions and legible source information are available.
