Could anyone please help me with some troubleshooting!

I am new to grasshopper and I have been following a tutorial. When I followed the instruction; it wont work. Since I will lasercut a file tomorrow it would be great if someone could correct my mistake and tell me what I did wrong. I would be more then happy if someone could spend a couple of minutes finding my mistake.

The problem started when I was creating the end of the tabs. The mistake resulted in a mesh of lines which should not be there.

This is the tutorial and I think my mistake is about 3 minutes in! http://www.digitaltoolbox.info/grasshopper/offset_scale.html

I am very thankful for all ideas, solutions and explanations!

Hi Jonatan,

The problem that you are faced with is that GH is a continually evolving entity. When the tutorial was made GH handled the data output of particular components in a different way. Instead of producing 3 curves from the scale component all bunched together it now produces a tree of curves with each curve residing on its own branch. The only solution is to use the path mapper component to collapse the last branches into the one above.

Note: This is why you had 243 curves coming out of the first List Item component and none out of the other two as there weren't 3 items to chose from.

Thank you very much for your help, now it works! My last question is how you export these triangles as a dwg to autocad and how to change there layers?

Once you are satisfied with your geometry, select the last two components on your canvas (ie the curves that you produce) and click the Fired Egg icon on the tool bar this will Bake them into Rhino. Then you can save the Rhino file as a DWG in the usual way. When you bake the objects you will be prompted to select a Layer in Rhino to add them to.

I can't remember why I didn't use the pathmapper on this... Everyone puts their own twist on this tutorial. Anyway [Offset] is the evolutionary culprit...

You must be getting old Taz! You did use the path mapper ;)

Jessh... Maybe if I actually read through all of my pearls of wisdom I wouldn't have to remember what I was thinking.

Anyway, just collating discussions into an untangleable web so I can find things when I do lose my memory...
