The issue of inconsistent parameter display between Rhino and Grasshopper

As shown in the image, this curve fails when using the Pipe command. I came up with a solution, which is to reparameterize the curve, and then the Pipe command works successfully. What is strange is that the parameter distribution of the curve is displayed differently in Grasshopper and Rhino. Which parameter distribution is correct? What is the reason for the Pipe command failure?thank you,everyone

It looks fine both in Rhino 7 and Rhino 8

It’s really strange, it doesn’t work in both Rhino 7 and Rhino 8. I’ve asked others, and they couldn’t get it to work either. Also, if you look at its parameter distribution, there seems to be an issue. The curve is supposed to be non-rational, but it’s displayed as a rational curve

I think you need to purchase a Rhino license to fix this issue…

The list option shows it as a rational curve, but in Grasshopper, it shows that the weights are the same."

好吧,谢谢
