Symmetry definition question

Hello!

I'm relatively new to Rosetta and I'm trying to apply symmetry in the BlueprintBDR. As I only know that I want C3 symmetry I used the general symmdef file for this symmetry. Still, I noticed that it just rotates the subunits with no translation from the COM of the arrangement, which leads to an overlap in residue coordinates, which in turn leads to problems in the minimization protocol. I have attached a picture of an example of what I got and the symmdef file used to obtain it.

Any help is greatly appreciated!
