Optimizing eccentricities in a Reciprocal Frame assembly

Hi!

Currently I'm working on the optimization of eccentricities (lengths) between bars in a Reciprocal Frame assembly. I want to equalize and control these lengths with Kangaroo and I'm trying to accomplish this goal with Kangaroos LineLine component. However, when using this component the orientation of the bars change in an undesirable way from a structural point of view.

Is it possible to use for example 'plastic anchoring' of points or something else to maintain the structures original element orientation but still be able to optimize the eccentricity lengths (see pictures below)?

I've furthermore tried to treat the eccentricity lines as springs but this didn't gave me a proper result.

Before optimizing

After optimizing with Kangaroo

Hope to hear from you.

Kind regards,

Tom
