Scene Menu

The Scene Menu contains the most commonly used functions to manage the Product Structure (tree), in order to optimize it:

Menu option	Description	Keyboard Shortcut
Merge Final Level	Converts all final Assembly nodes of the selection into Parts by merging their children. A Final Level designates an Assembly node whose children are exclusively Part occurrences.
Merge By Tree Level	Reduces the Product Structure (Tree) depth by merging together all Parts located at the specified Tree Level. The Tree Level designates the level at which an occurrence is positioned in the Tree (Root node is Level 0)
Merge Parts	Merges all selected Parts together, as one single Part
Merge Parts By Assembly	Merges together into one Part all Parts contained under each Assembly node of the Product Structure
Merge Parts By Name	Within a selection of Parts, merges together into one Part all Parts sharing the same name (identical "Name" property)
Merge Parts By Material	Merges Parts of the selection that share the same Material Property
Combine Meshes By Materials	Combines (merges) Parts of the selection by visible materials. The visible material is the material displayed on a polygon in the viewer (not necessarily the one set as a Material Property of the Part that owns the polygon: see About Materials). This function is equivalent to executing successively Explode By Materials then Merge Parts By Materials.
Transfer CAD Materials On Part Occurrences	All materials inherited from a parent node or from the CAD surfaces of a Part are transferred to the Material Property of this Part. This action is executed for each Part of the hierarchy. This makes the material management easier in Pixyz Studio.
Compress Tree	Compresses a sub-tree of the Product Structure (Tree) by removing empty nodes, or any node containing only one sub-node, and by removing useless instances
Rake Tree	Simplifies the Product Structure (Tree) by transferring all occurrences under the Root node of the scene (flattens all transforms)
Delete Empty Occurrences	Deletes Assembly nodes without children (Empty)
Apply Transformation	Used to change the transformation matrix of a selection
Create Symmetry	Creates planar symmetry from a selection
Make Instance Unique	Destroys connection of a selected Instance with its other instances, making it unique (also called singularize)
Create Instances By Similarity	Creates instances when there are similar parts. This can be used to repair instances or to simplify a model that has similar parts that could be instanciated instead to reduce the number of unique meshes (reduces drawcalls, GPU memory usage and file size). Using 1.0 (100%) in all similarity criteria is non destructive. Using lower values will help finding more similar parts, even if their polycount or dimensions varies a bit
Remove Useless Instances	Remove instances where they are not needed (prototype referenced once, ...)
Reset Transform	Sets all transformation matrices of the selection to identity
Rename Long Occurrence Name	Automatically reduces the character length in Assembly and Part name attribute to the specified value

NOTE Optimizing the Product Structure can be very beneficial to limit the number of draw calls and maximizing performances in the final staging tool (Unity for example), as less transformation matrices are computed.
