Drawing Print Output Naming Convention

This article explains how RedEye names exported drawing PDF files and why the exported filename may differ from the original uploaded filename.

Logic behind the naming convention

When you upload a drawing to RedEye, the system stores the original filename for reference purposes, such as cross-reference (XRef) matching. However, the drawing itself is assigned a Drawing Artefact Number.

In many cases, the Drawing Artefact Number differs from the original filename. This is because filenames do not always follow an engineering document numbering standard, while artefact numbers are typically based on each customer's document management requirements.

When you export a drawing, RedEye names the PDF using the Drawing Artefact Number, not the original filename.

Why we use the Drawing Artefact Number

A drawing can be updated multiple times during its lifecycle. New file versions may have different filenames, but the Drawing Artefact Number remains unchanged.

Using the Drawing Artefact Number for exported PDFs provides a consistent identifier that:

• Matches the drawing record in RedEye.

• Remains unchanged across revisions.

• Makes drawings easier to locate in search results.

• Helps users identify files outside RedEye, such as in Windows Explorer.

Document-type artefacts typically retain the original filename as their RedEye number.

Special character handling in exported filenames

Some characters used in artefact numbers are not supported in filenames. When RedEye exports a PDF, unsupported characters are replaced with underscores (_). For example:

Artefact Number	Exported Filename
123/ABC	123_ABC.pdf
Drawing A-01	Drawing_A-01.pdf

The following characters are replaced with underscores:

• Space

• Double quotation mark (")

• Apostrophe (')

• Ampersand (&)

• Backslash (\)

• Forward slash (/)

• Question mark (?)

• Percent sign (%)

• Asterisk (*)

• Colon (:)

• Vertical bar (|)

• Greater-than sign (>)

• Less-than sign (<)
