Hi,
I’ve got another problem with a script I’m updating for rhino 6/7 (actually just 6 for now) and something isn’t working right because Rhino.OffsetCurve behaves differently than in 7 (or in 4? What the heck was going on with v6?) I’m trying to offset an arc and it’s not being offset in the plane I want, it seems V6 is refusing to offset the Arc in any direction except for the plane of the arc itself. The “direction” pick point is the same in V6 and V7, which is a point some distance below the center of the arc, and I’m using a Normal vector direction. V7 works with any normal vector remotely in the right direction, V6 isn’t working with that or a more exact specification. The arc is at some arbitrary angle and I want it offset “down”. I guess I can probably rearrange my order of operations a bit to get around this, but any ideas where these differences are coming from?
