PDF files generated from AutoCAD drawings store SHX-font text as geometric objects.

TrueType text will maintain its fidelity when the same fonts are available on your computer.

Dimensions become individual lines, 2d solids, and mtext objects.

Hatch patterns become many individual objects without associativity.

By default, non-continuous linetypes become separate collinear objects.

Block references become geometric objects as if exploded.

More about inferences later.īehavioral losses when converting a drawing to PDF include the following: Note: The accuracy that’s lost is difficult to restore without employing inferences. These differences are most noticeable when working with large distances and dynamic ranges, as is common with large maps.

As a result, objects will be modified slightly when you output geometric data to a PDF file. Object associativity such as is available with hatches, blocks, and dimensionsĭue to the difference in precision between PDF and DWG formats, the values for coordinates, angles, distances, and widths are rounded off in PDF format.More than 60 types of geometric objects, including compound objects such as dimensions, hatches, and blocks.Real numbers that are represented with double-precision floating-point accuracy, which is several orders of magnitude more precise than single precision.In contrast, the data in AutoCAD DWG format supports a far richer data set including the following: Several properties that include primarily colors, layers, and line widths.Five graphical object types: path (line segments and Bézier curves), shading, TrueType™ text, inline image, and external.Real numbers that are usually represented with single-precision floating-point accuracy in recent versions.The data in PDF format supports the following: There’s a profound difference between PDF and DWG files in data content, format, and structure.
