How to bake vectors from GH to Rhino

Hi everyone,

I am new to Grasshopper and have a question about baking. I can display vectors in GH, using command "vector display". But I also want to bake it to Rhino. That is, I can still see the vectors after I turn off preview in GH. But now after I clicked "bake" I still don't see anything in Rhino. Does anyone know how to resolve this? Thanks!

Rhino doesn't have vector geometry, so I think the easiest is just to make Lines and bake those. You'll have to assign arrowheads yourself, which can be a lot of repetitive work. You can also try to create dimension objects in GH and bake those.

Hi Lydia

Like david said,Rhino doesn't have vector geometry, so I think the easiest is just to make Lines and bake those.

Then use rhinopythonscript (EditPythonScript)

import rhinoscriptsyntax as rs
lines = rs.GetObjects("Pick some lines", rs.filter.curve)
if lines:
for i in lines:
rs.CurveArrows(i,2)

Also the 'decorations' option on that bake window should have arrow options. I forgot about that.

Thanks for your reply! I've tried that, but it seems I can't change the arrowhead size as what we can do in vector display. Some of my lines are really short, so the arrowheads looks too big.

Thanks! I tried your script and it works. But I was wondering if there is any way to change the arrow size? Since some of my lines are really short, the arrowheads seem to cover them entirely...
