Hi there,
I am currently doing some experimenting with MOI 3.x and I wanted to make a nsided surface.
I the attached picture you see the shape of the hole I want to close with the nsided surface.
But no sucess yet. I tried to do it but never got any results at all.
Any ideas how that happens?
Besides, I was looking for some instructions to the NSided command, but failed there too ...
Regards
Heiner

Hi Heiner

Please post .3dm file.
N-Sided uses Edges, not the curves.

Hi Brian,
here is the part in question,

Yes, the part has a curve object in the selection area.

You'll also need to trim the edge of the default style piece to meet the orange style edge when selecting (It currently runs past it)

Use the types browser and hide "curves".

Hi Heiner, also in addition to what Burr wrote above it would probably be a good idea to construct the top flat side as one long piece rather than having it split up into many smaller sections. N-sided treats each each side with an equal weight basically and when they are out of proportion to each other like some much smaller than others it can make for bad results.

I've attached a version here with that back side reconstructed as one large piece using Network. Then the surrounding edges can be selected (as written by others above you need to select _edge_ objects for input to N-sided, if you have regular curves that won't work), and tone down the bulge a bit to get this kind of result.

Hello,

It looks like some of the edges are racked and you have a few little edges that can cause you problems. Using your model as reference model, I started with some rectangles at the corner points, filleted those rectangles, then used the blend tool to blend the construction lines together to form the edges of the and then swept the surfaces (you could use network in some areas as well if you find a better result). I joined the swept surfaces together to form a joined surface then used the NSided command to patch that hole. Having less points helps you sometimes because it makes modification easier down the road. Little tiny tweaks and many points do not usually help you like they might in a poly modeler.

This 2010 paper on blending showed up in my google searches.
Possibly it would be of interest, or has already been read?
