Diagram of the text to CAD pipeline: prompt, AI feature list, CAD kernel, editable partText to CAD Explained: From a Sentence to an Editable PartText-to-CAD tools promise a part from a sentence. The useful ones give you a part you can keep editing. Here is how that works and how to get good results.AI CAD · Text to CADMesh triangles versus an exact CAD circleMesh vs CAD: Which 3D Modeling Approach Do You Need?Mesh modeling and CAD both produce 3D models, but they store shape in different ways. Picking the right one saves hours.Basics · CAD · 3D modelingFour design rules for 3D printingDesigning Parts for 3D Printing: The Rules That MatterMost failed prints are design problems, not printer problems. These rules of thumb for FDM printing make parts that print first time and fit.3D printing · CADglTF and GLB file structure3D File Formats Compared: Which One Should You Use?The right 3D format depends on where the model is going. This guide compares the six formats people meet most often.File formats · BasicsThe same shape at 100, 50 and 20 percent of its polygonsHow to Reduce Polygon Count Without Ruining a ModelScans, CAD exports and marketplace models are often far heavier than they need to be.
