Layer-by-layer manufacturing covers more territory than most engineers realize. Laminated object manufacturing (LOM), sliced tooling blocks for composite layup, sectioned mold plates for waterjet stacking, large-format CNC where layers are cut and stacked — all of these need DXFs at specific Z heights. SolidWorks doesn’t have a “slice and export” button. But there are three workable approaches, and one of them scales with an API. The problem in concrete terms A customer operates a layer-by-layer cutting machine: it takes DXF profiles at fixed Z-height increments (say, 3mm steps), cuts each layer from sheet stock, and stacks them to build up a 3D form. Your job is to deliver fifty DXF files, each representing the cross-section of the part at a different height. ...

You spend ten minutes configuring the DXF export dialog — turning on bend lines, setting the layer map, choosing which sketch entities to include. You close SolidWorks. You open it the next morning and every checkbox is back to the default. Again. This is one of the most reliably frustrating behaviors in SolidWorks, and it has a specific technical reason that most documentation skips over. More importantly, there are three concrete fixes — ranging from a template trick to a four-line API call — that eliminate the problem entirely. ...

The marketing claim that Fusion 360 has “seamless” integrated CAD/CAM is technically accurate and practically misleading — depending entirely on where your design data comes from. This comparison breaks down how each approach works, where the integration claim holds up, and where it falls apart. For background on the broader platform comparison, see SolidWorks vs Fusion 360 vs Inventor 2026. How Fusion 360 CAM Actually Works Fusion 360’s CAM environment (the Manufacture workspace) shares the same file as the design. When you switch from the Design workspace to Manufacture, you are looking at the same geometry, in the same session, with no export or import step. The feature timeline is accessible. Selections persist. When you modify the model and return to Manufacture, setups reference the updated geometry. ...

The question comes up regularly on engineering forums: what do I actually lose if I move from SolidWorks to Fusion 360? The marketing pages from Autodesk give you the answer they want you to hear. This post gives you the engineering answer — what specific workflows break, what you have to rebuild from scratch, and where Fusion genuinely earns its place. For full platform positioning, the SolidWorks vs Fusion 360 vs Inventor comparison covers pricing, kernel differences, and which platform fits which team size. This post focuses narrowly on the migration decision: you have years of SolidWorks work, and you’re evaluating whether to move. ...

A Reddit thread in May 2026 caught the attention of the GIS community: a spatial analyst running QGIS headlessly via Claude Code, letting an AI agent execute processing algorithms and inspect outputs without ever opening the QGIS GUI. The post got 50 upvotes and 22 comments — more reaction than most QGIS workflow discussions — because it named something practitioners had been edging toward without a label. The shift is real. GIS professionals who already script via PyQGIS or QGIS Model Builder are discovering that qgis_process — QGIS’s native CLI tool for running processing algorithms — is a natural interface for AI agents. It’s discoverable, self-documenting, outputs JSON, and handles the full processing algorithm catalog without requiring a display connection. ...

A customer sends you a .stp file. It’s a sheet metal part — clearly visible bends, uniform thickness, nothing exotic. You import it into SolidWorks, run Convert to Sheet Metal, and SolidWorks does… something. A flat pattern appears. You run the DXF export and send it to the laser table. Then the first batch comes back wrong: the developed length doesn’t match the customer’s tolerance, some bends are reversed, and the corner relief geometry is completely off. ...

SolidWorks 2026 ships with AutoGenerate Drawing — an AI feature that takes a 3D model and produces a dimensioned 2D drawing with views, annotations, and BOM in the background while you keep working. LinkedIn posts about AI-generated macros and SolidWorks MCP servers are getting traction. The question is a reasonable one: if AI can generate drawings and answer questions about your model in natural language, what’s left for automation tools to do? ...

The problem with most “free GIS tools” roundup lists is that they treat GDAL, QGIS, GRASS, and PostGIS as competing products when they’re actually layers of the same stack. GDAL underpins QGIS. QGIS calls GRASS as a processing backend. PostGIS sits behind both for production data. Choosing between them isn’t “which is best” — it’s “which layer do I need to interact with directly.” This is a functional comparison: what each tool does well, where it breaks down, and which one to reach for when you receive a shapefile, a GeoJSON, or a KML and need it in something your software actually reads. ...

Someone emailed you a .slddrw file. Or you found one on a shared drive and need to know what it contains. This post answers the practical questions: what .slddrw actually is, how it differs from SolidWorks’ other file types, how to open it without a SolidWorks license, and what data you can and can’t extract from it. What is a .slddrw File? .slddrw is the file extension for SolidWorks Drawing files. These are 2D technical drawings — the dimensioned, annotated sheets that engineers produce from 3D SolidWorks models to communicate manufacturing requirements. ...

The thread A post in r/gis hit 101 upvotes this spring after a demo showed Claude performing CAD-adjacent spatial tasks. The 96 comments divided into three camps: alarm (entry-level GIS is gone), pragmatism (analysts who use AI will outcompete those who don’t), and dismissal (spatial analytics requires domain knowledge that LLMs don’t have). All three positions contain something true. The useful question is not “will AI replace GIS analysts?” — that framing produces either denial or panic, neither of which helps. The useful question is: which specific tasks are genuinely automatable, and what does that mean for how you spend your time? ...
