How this can be achieved in FME?

Source data – 2D point geometry with attributes 'FROM' and 'TO' (elevation values stored). The goal is to create 3D lines from those values.

Assign Unique Row ID if there isn't one already: Use Counter.
Send it first to VertexCreator:
- Mode: Replace with Point
- X: @XCoord()
- Y: @YCoord()
- Z: The "FROM" Attribute
Then send to another VertexCreator, and do the same with the "TO" Attribute. The result of both VertexCreators is transforming the 2D From and To Points to 3D Points
Pipe both of the VertexCreator's Output Ports to a LineBuilder
- Create the 3D lines from the now 3D Points by setting the "Connection Break Attribute" to the Unique Row ID / Counter Attribute
Depending on your Feature Order control in the Workspace, you may first need to put it through a Sorter to make sure it is ordered by From Points first, and To Points second entering LineBuilder.
One way to do this is to use a GeometryReplacer.

Set the Geometry Encoding to FME XML:
Enter the following XML:
<?xml version="1.0" encoding="US_ASCII" standalone="no" ?>
<geometry>
<line>
<coord x="@XValue()" y="@YValue()" z="@Value(From)"/>
<coord x="@XValue()" y="@YValue()" z="@Value(To)"/>
</line>
</geometry>Result:
The way to find this is to use a Creator to create a sample geometry, for example a 3D line.
Then go to the XML tab to find the FME XML.
Then replace the coordinates with placeholders.
Another thought, 3DForcer and Extruder could also be useful.
All three methods work just fine. Thank you guys!
