Irregular shape fills (is this supposed to happen?)

grizzler

I've been having bother filling irregular shapes so I'm trying to come up with ways of drawing that solve the problem for me. The straight forward example I've been attempting this morning is an arrow curved in 3d space which originates from a single point. The body and head are to be different colours so there is a line seperating them (see first pic). The way I thought of was to draw the arrow on the surface of a sphere using the 'arc' tool, but when I completed the arrow it failed to infil the body of the arrow, yet when I deleted the infil on the sphere and arrowhead the body became infilled automatically.

I hope I've explained myself clearly.

I'm more than happy to abandon this technique if you wise bunch can suggest a better method. I've not even got to the point where I show the arrow increasing in thickness from the origin to the point of the arrowhead

How big is the sphere? Could you post your model?

For fill curvated surfaces you have some plugs
Curviloft by Fredo6, Extrude edges Tools by Tig, Soap Skin Bubble, Ferrari

Or the Normal tool of the Sandbox

Assuming everything is a reasonable size [i.e. not tiny or gigantic] then make the FollowMe sphere separate from the 'overlay-edges' - or use ToolsOnSurface or draw it manually ater...
Also work with View > Hidden Geometry ON so you can see the segmentation edges etc.
Once you have the Arrowhead as a set of planes to give it thickness group and scale a copy of the Arrowhead and explode the bits and hand=stitch the nodes together to make it 3d...
Color as desired.

Looks like you have been shown a nice way or two to model your 3d arrow but I'm not sure about the stated problem of 'filling irregular shapes' and 'is this supposed to happen?' As was suggested if you post a model (or, less helpful, a pic with hidden edges displayed), someone can better see what may be going on. Better if possible to know what is going on than to work around the problem without a fuller understanding.
