Hello, Mr. Kwak Chang-gu :)
Thank you for using our UTTU CAD and contacting us.
1. Pattern creation not executed
When I checked the file, I found that the two ends of the front shoulder line do not touch the outer line.
Please check the image, modify it, and then try working on it.
2. Is it possible to modify the A/H lines at once by dragging?
The content appears to be about wanting to correct the overall curvature of the line.
After selecting the selection filter as "point", you can modify the overall curvature by dragging the point.
At this time, if you select two or more points together, the points will be transformed while maintaining their distance.
Please check the attached video and try working on it.
thank you
