Shift

Hi I am very new to grasshopper.

I am trying to divide a curve into points and extrude lines from the points. I got this to work.

Now I want to shift the points by 300. There is more I want to do...but I can't even get the shift command to work. I have attached a jpeg.

I have highlighted the points I want to move 300 in green.

Any help would be wonderful.

Shift will not physically move the points, shift is a list command and is just shifting your list values. If you want to move those points. First either use components such as cull components, list item, or dispatch and call them out. Then use move and set the vector to the direction you want to move.

The cull connected to the move are the points you want to move. The other cull is the inverse of the cull connected to the move. The moved list of points is then re merged with the inverse cull to "re create the list. then its connected to the line component. Note in the move I have the direction vector as x. That is the direction of the move. hope this helps. Theres many ways to go about this task.

I suggest reading the lists and tree sections in the primer as manipulation and understanding of these concepts are the core of grasshopper. Grasshopper = list management
