Hello,
my script currently looks like that:
I would like to have curves from the surfaces that I can then export. How can this be done?
In addition, it would be very helpful if someone could show me how to get letters from specific fonts into OpenNest and get the results as curves. I tried it like this:
I would be very thankful for help.
You didnât post code for your first image. In general though, Brep Edges and Join Curves does the trick.
As to the second image, Text needs an âLâ (Location) plane.
I donât think OpenNest wants circular âSheetsâ.
- System.NullReferenceException: Object reference not set to an instance of an object.
at OpenNestLib.OpenNestUtil.ToPolyline(Curve curve, Boolean collapseShortSegments)
at OpenNestLib.OpenNestUtil.ToPolylines(IEnumerable`1 nurbsCurves, Boolean collapseShortSegments)
at OpenNest.OpenNestFullComponentCleanUp.SolveInstance(IGH_DataAccess DA)
This works perfectly, thank you!
What if we use a rectangle? How can it be done then?
Yes. It solves that problem but there is more. Holes are a problem for OpenNest. Iâve tried to remember how to deal with that (purple group) but it seems cumbersome. OpenNest works with curves, not surfaces, so what you see is the Boundary component. But there is still moreâŚ
As you can see, OpenNest doesnât associate the two parts of the dotted âiâ, they are nested separately. Iâm not sure what to do about that. 
Later: having given it some consideration, I can just barely imagine a solution but itâs elaborate, complicated and likely fragile so Iâll leave it for someone else. @Petras1 ? How does one nest âiâ and âjâ text?
When all else fails, stop! Step away from the keyboard and do something else.
Though all this gets from OpenNest is the bounding boxâŚ
Very cool, thank you!
You need to convert curves to polylines then pass it as a boundary surface.
Very peculiar that OpenNest is happy with holed boundary surfaces only if they are created with polylines? It doesnât address the issue of keeping the dotted âiâ parts together.
Here is a step in that direction. The cyan group is only for reference.
This thread title should include the word âOpenNestâ, eh?
Looks great, thank you!
I was also wondering if itâs possible to give the letters a random size within a certain range and came up with this:
Unfortunately, it doesnât work well yet. The R always stays the same size, and changing the number of steps changes the word. Actually, a random command is also missing. Do you have an idea how to improve this?
It works, thank you!
