Hi,
I have several alignments in a coordinate system (SYS34 for Denmark) and I need to change it to another coordinate system (DKTM3 for Denmark), but when I do that the alignment is not completely moved and it looks funny as seen in the picture that I attached.
Where does it go wrong or why?
I am using PowerCivil for Denmark (SS4) v8.11.9.833
So from your other post, you said you get this "bad" result for other alignments, but not plain MicroStation elements. You can reproject plain "dead" graphics, but when you try to reproject alignments to this new coordinate system, you get the issues shown above.
Can you reproject from SYS34 for Denmark to any other coordinate system successfully?Can you reproject to DKTM3 for Denmark from any other coordinate system successfully?
I don't know much about reprojections (honestly) but that might help narrow down if it's a problem with the coordinate systems, or with the civil geometry.Hopefully, the folks with more knowledge than I will be along to help you further.

Is the reprojection a simple rotation (like in your post (x,y) -> (y,-x)) or does this also scale as you reproject?
I am asked if I want to do a reprojection when I change my geographic coordinate system (from sys34 to dktm3, for example) and I say yes.
and it seems that some parts of the alignment are 'stuck' in the original position, especially transition curves
I am shamelessly taking MaryB's statement and reusing it - "I don't know much about reprojections (honestly)". However, have you tried creating a new DGN with the GCS set to DKTM3, and referencing in the first (SYS34) DGN. The reference dialog should have a 'Reprojection' option.
Just to see if it will put the reference file into the correct place.
