What is explode in AutoCAD?
Explodes a compound object when you want to modify its components separately. Objects that can be exploded include blocks, polylines, and regions, among others. The color, linetype, and lineweight of any exploded object might change. Other results differ depending on the type of compound object you’re exploding.29 mar. 2020
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.17 déc. 2019

What is normal to ellipse?
The equation of normal to the ellipse x2a2+y2b2=1 at (acosθ,bsinθ) is axsecθ–bycscθ=a2–b2. The locus of middle points of parallel chords of an ellipse is the diameter of the ellipse and has the equation y=2am. The condition for y=mx+c to be the tangent to the ellipse is c=√a2m2+b2.
