[Q]:Blendcrv component vs Blendcrv command

Hi friends,
Firstly I want blend two surfaces.But there is no blendsrf component in gh natively, so I intend to use the blendcrv component to get one section curve firstly and then use sweep2 component to get the same result in rhino.
Then I notice that the output curve is somewhat strange and I can not get same result contrasting with Blendcrv command in Rhino.
I probably missed somethings so I need your help.Any hints?

It seems that blendcrv component’s bulge values are 1 in default, and at the same time blendcrv command’s bulge values are not 1 in default.
