Engineers searching for “Power Automate convert CAD” are usually trying to solve one of two problems: they have a folder of DWG or STEP files that need to be converted on a schedule, or they want to trigger conversion when a file lands in SharePoint. Power Automate can do both — but the mechanism is different from what most people expect, because there are no native CAD connectors in Power Automate’s connector library. ...

If your shop uses SolidWorks and your supplier’s shop uses Inventor, at some point you will end up comparing notes on batch DXF export. Both platforms flatten sheet metal and write DXF files. Both can be automated. The workflows look similar from a distance and differ substantially in the details that matter for production pipelines. This is a comparison of the actual automation approaches, not marketing specs. Platform capabilities are drawn from the COM API (SolidWorks) and the ObjectModel/iLogic API (Inventor). ...

You have 200 DWG files. Your fabricator wants DXF. Your documentation portal wants PDF. Your web team wants SVG. And nobody has an AutoCAD seat on the machine doing the conversion. This is the actual situation most engineering teams end up in. This guide covers every viable path to batch DWG conversion for all three output formats — what each tool actually supports, where each one breaks down, and how to script it so the conversion runs unattended. ...

The checkbox that lies to you Open a multi-body sheet metal part in SolidWorks and try to export DXF. File → Save As → DXF → Options. The “Export multiple flat patterns to single file” checkbox is greyed out. So is the standard “Flat Pattern” export mode. The dialog offers you geometry, hidden lines, and sketches — everything except what you actually need. This catches shops transitioning from separate-part workflows to multi-body assembly files. The multi-body approach makes sense for welded sheet metal assemblies: fewer files, shared reference sketches between bodies, no insert-part reference chains that break when you rename anything. But the DXF export dialog treats the whole assembly as one thing and can’t figure out which flat pattern to export. ...

If you work with sheet metal in SolidWorks, you have three realistic options for getting flat-pattern DXFs out at scale: write a VBA macro, buy PDMPublisher, or use CadShift. Each solves the same core problem — the repetitive manual export — but they sit at very different points on the complexity-vs-cost curve. This is a buyers guide, not a pitch. The right tool depends on your shop’s specific situation. The problem all three tools solve The native SolidWorks workflow for DXF export does not scale. For one part, the right-click → Export to DXF/DWG route is fine. For an assembly with 40 sheet metal parts, you are looking at 30–45 minutes of clicking through the same dialog, checking flat patterns, setting file names, and ensuring consistent layer settings across every export. Miss a part and your laser operator finds out at the machine. A detailed walkthrough of what the manual process involves is in the batch DXF export guide. ...

AutoCAD is the closest tool to the DXF format itself — AutoDesk invented DXF, and the format tracks AutoCAD versions. That proximity creates a false sense of safety. AutoCAD drawings destined for laser cutting fail for reasons that have nothing to do with version support: phantom geometry, Z-elevation surprises, splines the controller can’t handle, and blocks that CAM software silently ignores. The problems are consistent and avoidable, but only if you run a specific command sequence before every export. ...

The laser cutter doesn’t care where your DXF came from. It cares whether every cut profile is a closed polyline at the right scale with no phantom geometry hiding on invisible layers. Illustrator and Inkscape both produce valid DXF files — just not automatically. Both tools were designed for screen output, not manufacturing tolerances, and that mismatch shows up in specific, repeatable ways. This post covers what actually goes wrong in each tool and how to fix it before your file reaches the machine. ...

A GIS analyst exports a parcel layer from QGIS as DXF, opens it in Rhino for an urban design project, and a third of the parcels are missing. The ones with courtyards — inner holes — come in as the outer boundary only. A few with weird digitizing errors don’t come in at all. The analyst checks the QGIS layer: everything is there. The DXF is the problem, and so is the path that was used to produce it. ...

Two posts in the last week on r/SolidWorks surface the same class of bug: DXFs that look fine in SolidWorks land corrupted downstream. One user watched bend lines lean off-axis on a small flange until they dropped the end point merging tolerance from 1 to 0.1. Another spent a week re-ticking the entity checkboxes on every export because SolidWorks does not remember them. Both problems come from defaults that SolidWorks ships and almost nobody documents — buried in a bitmask you only see if you touch the API. ...

The Hours You’re Not Getting Back Ask any engineer where their time actually goes, and the answer is rarely “designing.” It’s exporting files. Converting formats. Renaming outputs. Running the same five steps in the same order for the twentieth time this month. That’s not a skills problem. It’s a workflow problem — and it’s exactly what CAD automation is built to fix. If you’re a mechanical engineer, CAD manager, or GIS professional who suspects too much of your day is going to work a script could handle, you’re probably right. This article covers what CAD automation actually means in practice, which tasks are worth tackling first, and how engineering teams are using it to reclaim real hours without changing how they design. ...
