CATIA V5 · Part Design Intermediate · Patterns & Multi-Body Once you’re comfortable with the fundamentals — Pad, Pocket, Shaft — it’s time to work smarter. Modeling complex parts efficiently means knowing how to stop drawing the same feature over and over, and how to organize a part’s geometry in a way that actually scales. […]
CATIA V5 · Part Design · Solid Modeling 3D solid modeling in CATIA is fundamentally about taking a 2D sketch and turning it into a physical 3D shape. You push a cross-section upward, spin it around an axis, or cut material away — and through a combination of those three ideas, you can build virtually
CATIA V5 · Sketcher · Fundamentals Before you can create any 3D solid in CATIA, you have to go through one essential first step: the Sketch. Whether you’re using Pad, Pocket, or Shaft, every 3D feature starts from a 2D Profile drawn inside the Sketcher workbench. “Sketching in CATIA isn’t really about drawing — it’s
CATIA · CATDUA V5 · File Optimization If you’ve been working with complex CATIA assemblies for a while, you’ve probably run into it: the file gets bloated, loading times creep up, and CATIA starts crashing on Update All for no obvious reason. The culprit is usually invisible — ghost links and leftover dummy data that
CATIA · CGR · Assembly Management If you’ve ever opened a large CATIA assembly — one with hundreds or even thousands of parts — and watched your PC grind to a halt, you know the frustration. To handle this, CATIA offers two distinct loading modes: Design Mode and CGR Mode (Visualization Mode / Cache Management).
AutoCAD · AutoLISP · Text Utilities Here’s a scenario every drafter knows: you need to paste the same text string into a dozen different text objects across your drawing. You can use MA (Match Properties) to copy formatting, but there’s no built-in AutoCAD command that overwrites one text object’s content with another’s. “Click the source
AutoCAD · File Management & Plotting Ever finished a drawing only to find the file is inexplicably huge? Sent a DWG to a client and gotten a call saying they can’t open it? Plotted a sheet and ended up with line weights all over the place? These are classic signs of poor file hygiene and
AutoCAD · Hatch Whether you’re showing a cross-section on a mechanical drawing or differentiating wall materials on an architectural plan, Hatch is the tool that gets the job done. The command itself is straightforward — but in practice, you’ll often run into that frustrating “Unable to determine valid boundary” error and wonder where things went
AutoCAD · Blocks If you’ve spent any real time drafting in AutoCAD, you’ve probably found yourself drawing the same shape over and over — bolts, nuts, title blocks, weld symbols, you name it. Copying geometry every time works, but it’s messy and a nightmare to update. Change one bolt and you’re hunting down twenty copies
