Hi mdesign, it's intentional - in MoI the result in the rails direction is going through an adaptive fitting process. In some limited special cases it could be possible to not do that if the conditions are just right. I think in Rhino there's some kind of "simple sweep" option for doing that. MoI does not have that function currently.

That`s ok because in the other side Rhino has NetworkSrf with more dense mesh and there is no option to make it lower like in MoI.

It`s a quite funny because in Rhino I should omit NetworkSrf If I would like have lower mesh and in MoI I should use Network (exact) if I want lower mesh. Sweeps mirror that situation. Because in Rhino I will get lower sweep than in Moi :)

It`s a new info for me because I`ve thought I will have same effect on both and there is no difference where I will create sweep and where I will create network.

Thanks for answer.

Cheers

Edit: In attachment I showed networksrf in Rhino (very dense without any options)
