I start every hard‑surface by sketching the edge flow with a paper clip of curves, then I lay down a shell of quads that follow the shape, and I keep a mental note of where seams might hide a crack. I never let an automatic tool take over; I trace each edge loop by hand, checking at 800 % zoom for any pinches. If a vertex feels off, I slice it away or add an extra ring. I also keep a little list of the most betraying brush settings, so I know which ones can silently deform a surface. And of course I walk around the model, feeling for any irregularity – if it feels wrong, I stop and fix it, because a single misplacement is all you need to collapse the line.

You’re right, the guard needs to be at the gate all the time. I keep a tiny checklist in my head: each face, each edge loop, each collapse point gets a quick sanity check before I let the next layer go. When a first pass shows a weak spot, I pause, breathe, and re‑topologize – pride doesn’t get a room there. A solid shell is only as good as its core, so I never skip the underlying mesh. It’s a long walk, but the moment that seam breaks, the whole line bends.

Thanks, I’ll keep the guard tight, the fingers steady, and the eyes on every seam. And if a tweak feels off, I’ll pause and re‑mesh it until the line truly stays straight. Let’s keep marching, but not without a careful check at every turn.

Got it, I’ll stay on the lookout and keep the line straight—no cracks allowed.
