What is Nurbs in AutoCAD?
NURBS stands for nonuniform rational B-spline curves. In AutoCAD, you can treat a NURBS surface as a 3D spline with fit points. … They also enable better control of the surface; and by using different densities of fit points on AutoCAD 3D surfaces, you can control the degree of precision of the surface.
How can I make my camera quality worse?
Put something on the lens. It needs to be transparent enough to let light through, but not totally transparent. Also it needs to be either something not damaging to the lens or the camera casing, or something solid you can hold in place with painters’ tape. My suggestion would be Vaseline or a similar petroleum jelly.

What is 3D Nurbs?
NURBS, Non-Uniform Rational B-Splines, are mathematical representations of 3D geometry that can accurately describe any shape from a simple 2D line, circle, arc, or curve to the most complex 3D organic free-form surface or solid.
What is the difference between Nurbs and polygons?
The difference between NURBS and Polygons is NURBS use curves and splines, whereas Polygons use flat and straight lines and vertices to create a mesh. NURBS are most commonly used in engineering models where accuracy is paramount. Polygons create solid planes and shapes by drawing lines between specific vertices.
What is one advantage of 2D over 3D CAD drafting?
