DraftSight: A Complete Beginner’s Guide to 2D CAD

How to Migrate DWG Files to DraftSight (Step‑by‑Step)

This guide walks you through migrating DWG files into DraftSight safely and efficiently, including preparation, import, verification, and cleanup. Assumptions: you’re using DraftSight 2024 or later on Windows. Adjust paths and exact menu names slightly for other versions or macOS.

1. Prepare source DWG files

1. Backup: Copy original DWG files to a separate folder (e.g., C:\DWG_Backup).
2. Collect dependencies: Gather external references (Xrefs), images, fonts, and plot style (CTB/STB) files into the same folder.
3. Audit and clean (Optional but recommended): In the original CAD app (if available), open each DWG and run AUDIT and PURGE to fix errors and remove unused items.

2. Install and set up DraftSight

1. Install DraftSight from Dassault Systèmes if you haven’t already.
2. Set drawing units and template: Open DraftSight → File → New → choose a template that matches your project units (metric/imperial). Set page setup and units under Tools → Options → Drawing Setup if needed.
3. Configure support folders: Add the folder containing fonts, CTB/STB, and images: Tools → Options → File Locations → Support File Search Path → Add.

3. Transfer files into DraftSight

1. Open DWG directly: In DraftSight, choose File → Open → navigate to your DWG folder → open the DWG. DraftSight supports DWG natively; it will convert any necessary elements on load.
2. Batch open (multiple files): Use File → Batch Convert (or Batch Open) to load multiple DWGs at once. Select source folder and target version if prompted.

4. Resolve missing references and resources

1. Xrefs: If Xrefs show as missing, use the External References palette (type XREF) to relink them. Click each missing Xref → Attach → navigate to your collected Xref folder.
2. Images and fonts: If images or custom fonts are missing, DraftSight will flag them on open. Use Tools → Options → File Locations to ensure the image and font folders are listed, or reattach via INSERT/ATTACH IMAGE and TEXTSTYLE for fonts.
3. Plot styles: Place CTB/STB files into DraftSight’s Plot Styles folder or add their location in File Locations so plotted output matches the original.

5. Verify geometry and annotations

1. Check layers: Open the Layer Manager to confirm layer names, visibility, colors, and linetypes match originals.
2. Inspect blocks and attributes: Ensure block definitions and attribute values are intact using the BLOCKS palette. Explode and recheck if necessary.
3. Dimensions and text styles: Verify dimension styles (DIMSTYLE) and text styles (STYLE) render correctly; adjust scale, fonts, or tolerances as needed.
4. Measure critical geometry: Use DIST, AREA, and LIST commands to confirm dimensions and areas match original files.

6. Fix common migration issues

• Missing linetypes: Recompute or reload linetypes via LINETYPE command and ensure support paths include linetype files.
• Incorrect units/scale: Confirm drawing units (UNITS) and scale factors; use SCALE or DWGUNITS tool to convert units if required.
• Proxy objects: If proxy graphics appear, install the object enabler or use RECOVER to clean; some custom objects may not transfer fully.

7. Save and export

1. Save in DraftSight: File → Save As → choose DWG and, if collaborating with other CAD versions, select an appropriate DWG version (e.g., AutoCAD 2018) from the “Files of type” dropdown.
2. Create PDFs for review: Use File → Plot or Export → PDF to produce reviewable documents with correct plot styles applied.
3. Batch save/convert: For many files, use Batch Convert to save all drawings to the desired DWG version.

8. Test and handoff

1. Open saved DWGs in target environments: Verify files open correctly in other CAD software used by stakeholders (e.g., AutoCAD).
2. Run final checks: Re-run AUDIT, PURGE, and a quick visual review of key sheets.
3. Document changes: Note any conversions, missing features, or manual fixes applied during migration and share with the team.

Quick checklist (copy-paste)

• Backup originals
• Collect Xrefs, images, fonts, CTB/STB
• Install DraftSight & set template/units
• Add support folders in Options → File Locations
• Open or batch-convert DWGs in DraftSight
• Relink Xrefs and reattach images/fonts
• Verify layers, blocks, dims, and text styles
• Save as compatible DWG version and export PDFs
• Test in target CAD applications and document changes

If you want, I can produce a short PowerPoint-ready checklist or a batch-conversion command list tailored to your DraftSight version and OS.
