How to scale a Point Cloud (LAS) around a specific coordinate?

Steps in my transformation:

1) Translate X,Y

2) Scale around a specific coordinate (Local Coordinate System)

3) Rotate around the same specific coordinate as in step (2)

 

Thanks,

Tomer

If I understand correctly you want to have control over the point of scaling and rotating. One way to do this is to define the point of the geometry you want to scale and rotate around, move the object to 0,0 using the offsetter, scale and rotate, then move back to the original coordinate using the offsetter again.

Hello and thank you so much for the support - super useful. Being a rookie with FME, I do not take your guidance for granted.

One thing I can't figure out on my own: How\\where to define the point of geometry to scale and rotate around? Where should I type in the coordinate values of that specific point?

 

Thank you,

Tomer
