jackson6612 Posted January 12, 2011 Posted January 12, 2011 Facet: A three or four sides polygon that represents a piece (or section) of a 3D surface. On a certain CAD-related webpage I found "facet" defined as above. Is it correct? Generally "facet" is not defined this way. facet: http://www.thefreedictionary.com/facet Please help. Quote
irneb Posted January 12, 2011 Posted January 12, 2011 In all (except solid modelling) 3d creations ACad uses similar things, but calls them faces. The command to draw one at a time is 3DFACE - you're asket for 3 or 4 points, then for the next 1 or 2 points to continue the next face. Other ways of doing such in one go is to use PFace / 3dMESH / EdgeSurf / RevSurf / RuleSurf / TabSurf. Using the newer solid modelling you generally don't get faces - you end up with regions, which may be curved (e.g. a cylindrical / spherical region). Though it "shows" them faceted according to some of ACad's settings - this is only to improve 3d graphics performance - it's not actually drawn as such. Quote
