Multibody Parts OverviewA multibody part consists of multiple solid bodies that are not
dynamic.
Multibody parts should not replace the use of assemblies.
A general rule to follow is that one part (multibody or not)should represent one part number in a Bill of Materials.
If you need to represent dynamic motion among bodies, use an assembly. Tools such as Move Component, Dynamic Clearance, and
Collision Detection are available only with assembly documents.

Bridging is a commonly used technique in a multibody environment.
Bridging creates a solid that connects multiple solid bodies.This technique is useful when you create portions of the model
first and create the connecting geometry afterwards.
For example, when designing a golf club, you might know the specifics of the head and shaft design, but not necessarily how
they are connected. You can design the head and shaft first, then bridge the two bodies.

• You can manipulate multibody solids the same ways you manipulate single solid bodies.
• We can add and modify features, and change the names and colors of each solid body.
• A folder named Solid Bodies appears in the Feature-Manager design tree when there are solid bodies in a single part document. The number of solid bodies in the part document is displayed in parentheses next to the Solid Bodies folder.
• You can organize and manage solid bodies in many ways.• We can also create multiple solid bodies from a single
feature.
Part documents can contain multiple solid bodies.
For example, when you design the spokes on a wheel, you know the requirements of the rim and the axle. However, you do not know how to design the spoke. With multibody parts, you can create the rim and axle, then create the spoke to connect the bodies.

THIS PART IS MADE OF TWO SPHERES BOTH REVOLVED FROM THE ORIGIN.WE ARE GOING TO BOSS SWEEP AND CONNECT THE TWO PARTS,
WE NEED TO USE OVAL SKETCH AS THE PROFILE,AND OUR SPLINE AS THE PATH. THIS SPLINE CONNECTS THE
ORIGIN TO THE CENTROID OF THE OUTSIDE DIAMETER WHEEL

SELECT BOSS SWEEP AND MAKE SKETCH 2 THE PROFILESELECT SKETCH 3 AS THE PATH TO CONNECT THE TWO PARTS,
EXTRUDING FROM ONE BODY TO THE OTHER BODY, NEXT WE WILL DO A CIRULAR PATTERN TO COMPLETE THE PART.

THIS PART IS MADE OF 2 EXTRUSTIONS, NOT-COMBINED.THIS RESULTS IN AN ERROR OF MASS, VOLUME, AND AREA.
SINCE SOLIDWORKS SEES TWO SOLIDS ON TOP OF EACH OTHER
MULTI-BODY PARTSSOLIDWORKS TUTORIALS
THIS PART IS MADE OF 2 EXTRUSTIONS, COMBINED.THIS RESULTS IN THE CORRECT MASS, VOLUME, AND AREA.
NOW SOLIDWORKS WILL SEE THEM AS 1 SOLID PART.
MULTI-BODY PARTSSOLIDWORKS TUTORIALS
AFTER COMBINING THE TWO EXTRUSIONS TOGETHERWE CAN TELL WE HAVE THE CORRECT MASS, VOLUME, AND AREA.
Incorrect Correct

THE NEXT PART IS MADE UP OF TWO SEPARATE SOLID EXTRUSIONS.THEY LOOK LIKE MEASURING CUPS AND ARE NOT SHELLED YET
THE NEXT STEP IS TO EXTRUDE THE SKETCH FROM THE FIRST BODY TO THE SECOND BODY.WE WILL THEN SHELL THE BOTH PARTS SEPERATELY, WE WILL NOT SHELL IN ONE COMMAND.
MULTI-BODY PARTSSOLIDWORKS TUTORIALS
SOLIDWORKS WILL NOT LET ME FILLET THEM BOTH BECAUSE THEY ARE SEPARATE ENTITIES.SO WE WILL USE THE COMBINE COMMAND TO COMBINE THESE THREE SEPARATE EXTRUSIONS.
THIS ALLOWS US TO HAVE ONE SOLD PART THAT WE CAN FILLET IN ONE COMMAND

Exploded Views in Multibody Parts
An exploded view in a multibody part shows the solid bodies spread out, but positioned to show how they fit together.
You create exploded views by selecting and dragging solid bodies in the graphics area, creating one or more explode steps. In exploded views you can:• Evenly space exploded stacks of solid
bodies.• Attach a new solid body to the existing
explode steps of another solid body. This is useful if you add a new body to a part that already has an exploded view.
• Add explode lines to indicate relationships between solid bodies.
While a multibody part is exploded, you cannot add mates to it.

Bill of MaterialsWeldments are a
classic example of a proactive reason to use
multibody parts. Weldments are much easier to create as a
single part file. You also still have ‘bill of
material’ functions go get a complete part
count in the form of a weldment cut list.

Using Multibody Parts to Define Removed Material
You can assign operation costs to bodies that define the removed material. Alternatively, you can assign a cost per volume removed. For example, you can computer the cost of post manufacturing operations on cast parts by assigning operation costs to the bodies.
You can use multibody parts to define the removed material in a part

Conclusion:• Multibody parts have a reason and demand to be used.• It enables us to accomplish features that are not possible with assembly files.• While we create parts we can mate them at the same time. • Also capable of manipulating multibody solids to create geometry• When used with an assembly file the multibody part represents a completed
item where individual components are not tracked. • Generally when we buy an item with multiple components we view it as one
single item. This is also true with assemblies and multibody part files. • File management and performance are now improved since it is only a
SINGLE file, not several referenced files like assemblies.• You can still use all Clearance detections, Interference detections, and other
evaluation features it just views it as one part.
