Elements and the Assembly-Tree

Elements - What are they?

Element Names

When we do commands, we add elements to the model in the graphic-area.

Each element has a name.

Elements in the Assembly-Tree

The Assembly-Tree compiles the elements into a hierarchical and chronological list.

Each element has a unique name, number, and icon.

Element-Name + number

The first element of a type does not have a number. Thereafter, we append it with a number.

E.g. : As we add Parts, the Element-Names in the Assembly-Tree will be Part, Part2, Part3, .... ;

Element Icon

Each element has an icon to the left of the element-name

The icon is very similar to icon for the command in the toolbar.

You cannot change the icon.

You can rename all elements. See rename elements

Element Icons and Names

We can see the element that is renamed to Coupler is a Part, because the

icon identifies it as an element of that type.


The Assembly-Tree also indicates the kinematic-state of each Part with an icon.

The kinematic-state of each Part is important, but we will discuss that later.
