why are some values in my list the inverse??

Hello

I have two definitions where the list of the geometry seems to create one or more inverted values (negative instead of positive).

Please see below screen shots as well as the grasshopper definition.

The first one is offsetting some circles in the positive vs. the negative and the second is not lofting the curves correctly.

I can't seem to figure out why it's doing this.

Any help is appreciated!

Hi.

See red group.

You are better off providing each circle plane for offset and using "PFrames"to align your circle seams for loft.

Hello, this seems to address your issues. In both cases, its defining the right planes for your geometry.

1) We must give to offset comp. the appropriate plane for the curves.
2) Circle CNR not regularly defines the start of the circle (or the X axis of the plane for each circle, because it uses the normal (z axis)), you need to create aligned planes and there circles.

Lol.

Discussions should have an icon or warning as "someone is solving this discussion, please wait and do not waste your time".

Defining planes using only an origin point and a normal vector (which is what the Circle CNR component does internally) is insufficiently rigorous for use in components such as Loft.

You should use Curve Perpendicular frames if you want the X and Y directions of successive planes along your curve to match with their immediate neighbours.
