when you created the deformed shape was the plot at one to one scale??
Yes, the plot is at 1-to-1 scale.
Since I posted this message, SW put out a Critical SPR 518624 , because they recognized it's a big flaw in the Export Deformed Body feature. Their conclusion was "The deformed solid body is way off from the actual deformed FEA plot."
I am more familiar with monkeying with Abaqus so I am not sure where you would find the specific files or syntax necessary.
You could skin the model with shell elements of trivial stiffness or possibly use the contact elements. In the input file grab the element and node definitions and in the output grab the deformations. Now apply those deformations to the nodes. Now convert the FE node mesh syntax to STL (ASCII) and you have a deformed solid. I hope this helps.
