Create a mesh sphere
using one of several methods.
When you start with the center point, the central
axis of the mesh sphere parallels the Z axis of the
current user coordinate system (UCS).
You can set the number
of divisions for each dimension of new mesh spheres in the Mesh Primitive
Options dialog box. You can also modify
these settings and the level of smoothness as you create the mesh
object.
Mesh Sphere Creation Options
The Sphere option of
the MESH command provides
several methods for determining the size and rotation of the mesh
spheres you create.
- Specify three points to
set the size and plane of the circumference or radius. Use
the 3P (Three Points) option to define the size of the sphere anywhere
in 3D space. The three points also define the plane of the circumference.
- Specify two points to set
the circumference or radius. Use the 2P (Two Points)
option to define the size of the sphere anywhere in 3D space. The plane
of the circumference matches the Z value of the first point.
- Set the location to be
tangent to two objects. Use the Ttr (Tangent, Tangent,
Radius) option to define points on two objects. Depending on the radius
distance, the sphere is located as near as possible to the tangent points
you specify. You can set up tangency with circles, arcs, lines,
and some 3D objects. The tangency points are projected onto the
current UCS. The appearance of tangency is affected by the current
level of smoothness.
To create a mesh sphere
- Specify the center of the sphere.
- Specify the radius or diameter of the
sphere.
To create a mesh sphere
defined by three points
- Specify the center of the sphere.
- Specify the radius or diameter of the
sphere.
CommandsMESH
Creates a 3D mesh primitive
object such as a box, cone, cylinder, pyramid, sphere, wedge, or
torus.
MESHPRIMITIVEOPTIONS
Displays the Mesh Primitive
Options dialog box, which sets the tessellation defaults for primitive
mesh objects.
System VariablesDIVMESHSPHEREAXIS
Sets the number of radial
subdivisions around the axis endpoint of the mesh sphere.
DIVMESHSPHEREHEIGHT
Sets the number of subdivisions
between the two axis endpoints of the mesh sphere.
DRAGVS
Sets the visual style
that is displayed while creating 3D solid and mesh primitives and
extruded solids, surfaces, and meshes.
