Never attempt to build a complex shape from a single feature. Begin by creating a master skeleton using a network of intersecting 2D and 3D sketches. These curves serve as the definitive boundaries for your future surfaces. Step 2: Build Primary Surface Patches
Simulates long parallel light strips reflecting off a glossy car finish. If the lines break or mismatch at a seam, you have G0 continuity. If they bend sharply, you have G1. If they transition smoothly without sharp kinks, you have reached G2 continuity.
Try to construct your geometry using four-sided regions. Surfaces mathematically prefer four sides; shapes with three or five sides often create center puckering. Never attempt to build a complex shape from a single feature

To create these organic designs, you must master surfacing. Surfacing allows you to build shapes face by face, controlling every curve, boundary, and transition. Step 2: Build Primary Surface Patches Simulates long
The surfaces share both a tangent vector and an identical radius of curvature at the boundary. The transition is perfectly seamless, meaning light reflections will glide across the seam without warping or breaking. This is mandatory for automotive bodies and premium consumer electronics. 5. Step-by-Step Workflow: From Surfaces to Solids
Blending a square into a circle, creating organic bottles, or transitioning from a sharp edge to a rounded form. If they transition smoothly without sharp kinks, you
To create a complex shape (like a motorcycle fairing or a designer mouse), you build the "zero-thickness" skin (surfaces). Only at the very end do you "knit" those surfaces together into a solid body.

The surfaces touch, and their shared edge shares a common tangent vector. The transition is soft to the touch, but a zebra stripe analysis will reveal a sharp kink in light reflections.
Solid modeling is volumetric. You start with a closed 2D sketch and add or remove mass. The software always knows what is "inside" and what is "outside" the model.
