Question 1

What is a DWG file?

Accepted Answer

DWG is the native file format for AutoCAD, the industry-standard computer-aided design (CAD) software. DWG files contain 2D and 3D design data including drawings, blueprints, maps, and technical illustrations. Converting to PDF makes these designs viewable without CAD software.

Question 2

Why convert DWG to PDF?

Accepted Answer

PDF conversion lets you share CAD drawings with anyone regardless of whether they have AutoCAD installed. PDFs are universally viewable, can be printed to scale, and serve as official documentation for construction, engineering, and manufacturing projects.

Question 3

Are layers preserved in the PDF?

Accepted Answer

Yes, CAD layers are preserved as PDF layers in compatible PDF viewers. Recipients can toggle layer visibility to view different aspects of the drawing. Not all PDF viewers support layers, but Adobe Acrobat and other professional viewers do.

Question 4

Can I specify the output scale?

Accepted Answer

ChatSlide AI offers scale control so your drawing prints at the correct dimensions. You can specify scales like 1:100 or fit to page. The free tool uses automatic sizing to fit drawings on standard page sizes while maintaining aspect ratio.

Question 5

What DWG versions are supported?

Accepted Answer

We support DWG files from AutoCAD 2000 through the latest AutoCAD versions. The conversion handles different DWG version formats automatically. If you have a very old DWG file that doesn't convert, try opening and re-saving it in a modern AutoCAD version.

Question 6

What about 3D models in my DWG?

Accepted Answer

Currently, 3D content is flattened to 2D views in the PDF output. The conversion produces standard 2D representations of 3D models. For interactive 3D viewing, consider 3D PDF formats or dedicated 3D viewers. 2D drawings convert with full fidelity.

Question 7

How is line weight and color handled?

Accepted Answer

Line weights, colors, and styles from the DWG are preserved in the PDF. The visual appearance matches what you see in AutoCAD. You can specify monochrome output or preserve original colors based on your needs.

Question 8

What page size is used for the PDF?

Accepted Answer

By default, drawings are fitted to standard architectural or engineering paper sizes (ANSI, ISO) appropriate for the drawing's dimensions. ChatSlide AI offers custom page size options and the ability to specify exact dimensions for professional printing.

Question 9

What is the maximum file size?

Accepted Answer

The free tool supports DWG files up to 100MB. This covers most standard CAD drawings. Very complex drawings with extensive detail may take longer to process but convert successfully.

Question 10

How long does conversion take?

Accepted Answer

Most conversions complete in 15-45 seconds depending on drawing complexity. Drawings with many elements, layers, or external references take longer. The conversion processes all visible content and generates a print-ready PDF.
