PCS - Correlation about 'Variable edit handle'

Hello masters~

I'm a student who studying AECOsim alone in S.Korea. Please understand my low level English :)

These days, I practice 'Parametric Cell Studio' for making some models by parameter like a Revit family.

I made one sample of retaining wall. 

But, unfortunately, it is not working well.

I understood one step about 'Variable edit handle'. Result is different along the direction that specifies 'Variable edit handle'.

But, sometimes model was rotated when I changed the 'Length' value after added 'DataGroup Catalog' and placed in AECOsim.

I cannot understand this situation.

Please let me know how to set-up the 'Variable edit handle' correctly.

PS. If you wanna check my model, plz let me know e-mail by comment. I'll send to you (PAZ file).
