Hi,
I'm afraid adaptive will always give you this issue if the splines are different lengths. Instead you could try the following.
- If it's not already set up like this, make sure that the straight edge on the right of your image is the first vertex so everything starts aligned
- Change the Default mode to Tiled
- Use the Scale Final Segment macro to only scale the last segment in the array. All the others will retain their original size and should remain aligned.
I hope that helps. If you need further assistance, please feel free to upload the RC style and its associated splines and I'll take a closer look.
Best,
Paul
