However, when I googled for different solutions, I came across a very interesting Rhino tutorial that achieves EXACTLY what I would like to do, but without using any nodes at all:
Here's an image from the tutorial:
That wiregrid to the left is what I'm trying to achieve.
So, first he extracts the wirefram from the original shape. This would be doable in Moi, using the ISO tool.
Then he rebuilds the curves. This is also doable in Moi, using the Rebuild tool.
Then he turn the curves into pipes. Also doable in Moi.
However, then he uses something called "Sub-d Multipipe" (around 5:40 in the video). This is not something I'm familiar with in Moi, and I found nothing on Google.
Is there something similar to Sub-D Multipipe in Moi?
If not, is there a workaround to achieve the same result, with or without the Node Editor?
If you export out from MoI into .obj format then bring that into TopMod I think it has some different kinds of framing methods for generating structures around polygon edges.
If it is able to build an all quad structure you could then export that back out to an .obj file and use the MOI sub-d converter (SubD > Create > "From file") to convert it into NURBS geometry in MoI.
