To recieve advise, you´d probably need to be a little more specific.

Best,

Are your triangles closed?

Hej.

They are closed.

Some of them just simply offset into the wrong direction.

And some just are extended....

OK. Some of this is related to the RhinoCommon offset routine using user supplied inputs at the time of running eg direction. There have been several work arounds to over come this problem such as Offsetting both sides and calculating the new curve lengths and culling the smaller/bigger etc.

I know David tried writing his own offset routine for GH but it would seem that there are too many hurdles as it is still not happening 100% of the time as desired.

If you search the Forum for Offset Bug you might find other's solutions to this.

There is an offset on Surface component which is more reliable but uses more processing time.

Which one do you think of?

One thing that has always puzzled me about Offsets in Rhino, why it can't offset a curve like this and give you both internals in one pick?

is it possible in Grasshopper?
