Why is sketch 3D model blurry when convert?

Sketch 3D models often become blurry when converted due to low original sketch resolution, insufficient polygon count in the 3D model, or incorrect export settings that lose fine details. Low sketch resolution means there aren’t enough pixels to retain sharpness when scaled to 3D. Too few polygons make edges and small details look jagged or fuzzy. Incorrect settings (like low-quality exports) can also strip away the sketch’s fine lines. To fix blurriness, try using a higher-resolution sketch, choosing a tool that preserves polygon detail, or checking export settings for "preserve detail" or "high quality" options.
