\page partition_explanation Fuse, Partition and Compound usage
\tableofcontents
It is frequently asked about the difference between the above mentioned operations. It's indeed simple. Lets take the example of a cylinder and a box that you want to join together.
\b Fuse
The \b fuse operation will make a <b>single solid</b> from the two given solids :
\section sec1 Fuse
The \b fuse operation will make a <b>single solid</b> from the two given solids. It allows you to build complex models by putting simple shapes together.

\b Partition
\section sec2 Partition
The \b partition operation will also allow connecting the two solids but it will <b>keep a face at the frontier</b> (in brown on the picture below). The resulting shape will consist in <b>two connected solids</b> that share
a face at their frontier. It means that this face is present only one time in the resulting shape and is a sub-shape of both the box and the cylinder.
The \b partition operation will do basically the same but it will <b>keep a face at the frontier between the two solids</b> (in brown on the picture below).
This face is shared by the two solids, which means that this face is present only one time in the resulting shape and is a sub-shape of the box and a sub-shape of the cylinder.
This operation allows you to identify different areas in a shape (e.g. different materials) and to ensure a conformal mesh when meshing it later. Indeed the face at the frontier is meshed only one time.
\n This operation allows you to identify different areas in a shape (e.g. different materials) and to ensure a <b>conformal mesh</b> when meshing it later. Indeed the face at the frontier is meshed only once.

\b Compound
\section sec3 Compound
When you build a \b compound by using the build -> compound operation you just make <b>an object that contains the two separate solids</b> like in a "bag".
The two solids remain unconnected. The compound is just a set of shapes, no more.
\n The compound Allows applying operations to a collection of shapes.

\note The shapes in the compound can be of different types : edge + shell + vertex ...
\section sec4 Summary
<ul>
<li> \b Fuse
<ul>
<li> \a Result : A <b>single solid</b>. </li>
<li> \a Purpose : Allows building complex models by putting simple shapes together.</li>
</ul>
<li> \b Partition

<li>\a Result : Several <b>connected solids</b> sharing faces.</li>
<li>\a Purpose : Useful to ensure a conformal mesh of separated areas of your model (fluid / solid , concrete / steel ...)</li>
</ul>
<li> \b Compound
<ul>
<li>\a Result : Several <b>unconnected objects</b> of any type.</li>
