How do I scale a model by different factors in X, Y, Z? The Scale Object block only allows for uniform scaling.
Instead of using the Scale Object block, use the Remap Scale Body block. This block allows you to scale the object differently in each direction.
This block is also a Toolkit, which is a combination of blocks. If you want to see how it runs, for curiosity's sake, Right-click on it and select 'Export Block'. Then, open it back up in nTopology to see how it is built.
