First Work : Curve created in GH editable in Rhino ?; Conditions

Hi All

Totally beginner on GH :

I started just today in order to define an "automatic" starting file, which could become a base for all my future works.

First Step : I want to create a closed curve > Move the center of this curve on the X axis

So i made this :

Problems:

1- I wanted Curve-01 move and not create another curve. I alreadycheck forum and see not possible > Is there a way to replace Curve-01 by Curve generated at the end.

2- If yes, we have to include a conditional statement that move only if Curve-01 center is not on X axis > So wider question : Is it possible to activate/desactivate a Component with Conditions.

3- Is it possible to Modify by control points in Rhino curve generated by GH?

Objects are referenced from the Rhino Document, but never altered. To "Replace" you just have to Bake the end product into Rhino. Right Click > Bake and then delete the original curve

Yes there are many ways to perform conditions in Grasshopper. The way that springs to mind is to check the Centroid of the Box with a [Closet Point to Plane] the Distance will be zero if you don't want it moved. Anything else when passed through a [Boolean] Param will be 1. this creates a logic either 0 or 1 to [Dispatch] your geometry either this way or that.
