Grasshopper - David Ruttens ’s Shift Tutorial
Software : Rhino 3d and Grasshopper (Explicit History)
Level : Beginner
Description : In this Rhino / Grasshopper video tutorial we rebuild the shift tutorial provided by David Rutten on the Grasshopper blog. I hope to do one of these per file David has posted up. As simple as the interface is to understand when one comes at the software for the first time this can be a bit overwhelming. I just want to help make the dissection process as simple as possible . Please have a look in the forum for more Grasshopper files and images.
Topics Covered
-Divide curve by Number
-XForms
-Using the Shift component

I got a question while I was following your instruction.
When I set the point for the circle, it set not as a reference but as a vector position.
So when I move the point, the circle doesn’t move as well as the point.
How can I fix it???????????????
post you definition file in the forum. I’ll take a look

Thanks for your reply, Dave.
I’m sorry but I don’t know how to post my file in the forum.
I will send you an Email w/ my rhino file and also the wrm file.

Dave,
Once you figure out the issue, could you post the solution in this forum since I am having the same issue as kim.
Thanks.

Hey,
I have that problem too, and i also can’t see points.
For example if I divide the circle I cant see the crosses where it’s divided.
If I go on and put the lines between the points the lines show up like they should.

when you guys make the circle in the grasshopper are you using a point at the origin for the circle. Make sure you are using the correct circle component.
Hey Dave,
Yeah, I first place a point and use that as origin just like you do in the tutorial, and also use the correct circle, have no idea whats wrong.
I’ll show a screenshot and the definition file in the forum.
Thanks!
I think that’s kinda error at the new version of grasshopper.
I prefer to make a point by the grasshopper now,
and link some slidebars to move the point.
Thanks for you great tutorials. I am not that familiar with Rhino, and I can’t seen to make the green (or red) X’s appear when I divide a curve. The curve is divided, however, there is no graphic to visualize the number of divisions.
question:
after you divide the two circles with the divide curve tool and use the line tool, why does grasshopper make a vertical line to connect the points that are directly below it?
why doesn’t it just make an array of lines that connects one point from the top circle to every point on the bottom circle?
is this just how the program is set up, or am i just really really confused?
