A surface represents the geometry associated with a physical part. A surface is a two-dimensional geometric entity that
may be used in automatic mesh generation.
Solids are closed volume of surfaces that can take any shape. Solids are three-dimensional entities that can be used in
automatic tetra and solid meshing.
Use the Midsurfaces tool to extract the midsurface of sheet metal stampings, molded plastic parts with ribs, and other parts that have
thickness clearly smaller than width and length.
When performing cleanup or defining simulation parameters, it can be helpful to first find and isolate certain types
of geometry. This will give you a better idea of the areas in the model you need to focus on.

Use the Solids: Sphere tool to
create spheres with solid or bounding surfaces.
From the Geometry ribbon, click the Solids > Sphere tool.
Create the sphere using one of the following methods:
Method
Procedure
Free Drawing
Left-click on geometry or in space to create the sphere's center
point.
Move your mouse to uniformly resize and draw the sphere.
Left-click to create the sphere.
Fit To
Select Surfaces,
Solids, or
Components from the guide bar.
Select the entity in the graphics window. A sphere will be
created.
Modify the location, if necessary, using the move tool () on the guide bar.
Modify the size and location of the sphere in the following ways:
Resize the sphere by editing the radius in the microdialog and pressing Enter.
Click on the face of the sphere and drag the slider to adjust the
size.
Click to translate
and rotate the sphere using the Move tool.
Click to fit the
sphere around a selected object.
Click to fill the
shape.
Tip: While placing or editing the sphere, use snap points to snap to predefined points on your model, such as
surface boundary fixed points or mid points of surfaces.
