Definition of solids in contact
Definition of solids in contact
Geometric objects that physically touch at points or lines
Where contact points appear in projection
Where contact points appear in projection
In all orthographic views (plan, elevation, auxiliary)
Definition of locus
Definition of locus
Path traced by a moving point under specific conditions
Where sphere contacts cone
Where sphere contacts cone
Where sphere's surface touches cone's slanted face
Sphere & cylinder contact on horizontal plane
Sphere & cylinder contact on horizontal plane
Circular plans touch but do not overlap
Definition of tangent plane
Definition of tangent plane
Touches solid at one point without intersecting interior
Tangent plane to sphere orientation
Tangent plane to sphere orientation
Perpendicular to the radius at that point
Tangent plane to cone contact type
Tangent plane to cone contact type
Touches along a line (generatrix), not a single point
