– Fundamental concepts every surface modeler must understand.
Guide curves dictate how the shape transitions between those profiles. If they do not touch, your Lofts and
When creating guide curves, ensure they pierce the profile sketches. If they do not touch, your Lofts and Boundaries will fail to generate. You are weaving a patchwork quilt of infinitely
Surfacing is zero-thickness geometry. You are not building a solid block. You are weaving a patchwork quilt of infinitely thin faces in 3D space. Why Use Surfacing? 3. Understanding Surface Continuity: G0
A swept surface moves a profile sketch along a defined path sketch. Advanced sweeps can utilize guide curves and twist vectors to create complex, undulating shapes like augers or specialized wiring channels. Boundary Surfaces
Look for smooth, gradual transitions in the combs. Sudden spikes or reversals indicate a defect in your curve that will ruin your final surface. 3. Understanding Surface Continuity: G0, G1, and G2
If a fillet keeps failing, it is usually because the underlying geometry is too cramped or poorly constructed. Build manual blends using the Trim and Boundary tools instead of relying on the automated Fillet tool.
