Grasshopper to Archicad 1D Structural Analytical Model

I’m running into knot incindets isues transfering a structural line model form GH to Archicad 24 (6004).
The Rhino side is made with an underlying a point grid using only the point snap. So in my opinion all line points must be coincident.
However transferring this line grid to Archicad via the beam component results in a weired non coincident structural analytical model.

Has anyone expiriend similar behaviour?
