@lemon thank you very much

but did you test it?

@lemon this is the results I get pasteall.org/pic/index.php?id=115181

lemon

@Tak hello, apply scale (as said many times in answers ; ) but there is a bug (corrected in the edited answer)

Tak

@lemon okay, will try it now :)

@lemon now works :)

lemon

good!

Tak

but how I can construct the faces?

and assign these faces to a vertex group

lemon

for now I don't know... I think converting to curve will fail...

Tak

like I think each vertex group can have one face as it's 2D

lemon

05:17

Well in fact, vertex group needs no face

But the answer as it is, would respond to your question but only before you edited it

But you have the freestyle approach too...

Tak

mmm, okay

lemon

You know: building faces here is the same problem as for fonts => hard

But some other approach may work (if someone find it)

do you need the faces ?

Tak

So this is what I did:

I selected a group of faces and pressed F to make face but it didn't work properly

will send a screenshot:

I need faces to set their color

lemon

Have you tried alt+F ?

Tak

any other idea? like for example, sometimes I want the head to be colored by a certain color sometimes the legs,.....

what I was doing before is that I have vertex groups and I have a material for each vertex group, then I select the vertexgroups vertices and assign their material color.

will try it now, 1 sec

lemon

05:26

you can select all and alt+F

brb

does it work? It does here

Tak

this is the results:

when selecting all vertices and hitting F

when selecting all vertices and hitting Alt+F

the first one is better as it has less than 100 faces but there is one face created which is not good as you can see

the problem with the alt+f one is that it has more than 4000 faces

lemon

well it is the third of the original... but you can decimate a bit I guess

or limited dissolve... but limited dissolve will lead to one big face

that was why I commented your question about the "hint": ok you want to remove faces but how to now which ones?

we need a hint for that

or... limited dissolve, then delete faces then alt+F again

that leads to 1800 faces here

but again, ok less faces, but probably not the faces you wish to keep, am I right?

Tak

05:42

I will show you my ultimate goal

so each space of these to be a separate face

I think one of the problems that there are many vertices especially in the feet, hands and face

lemon

So you can try the following:

Tak

and I don't mind doing this manually as I will only do it once, but I don't know how

lemon

Make some kind of grid from the red lines

and use it as knife project on the mesh

you see the idea ?

Tak

okay, I'll switch the computer, be right back in 5 -10 mins

lemon

ok

Tak

06:09

back

@lemon okay, will try now

lemon

ok

Tak

but to do this I need faces, right?

or I can do it using vertices without faces?

lemon

I don't remember... give it a try (I will do to)

Tak

okay

will try now

lemon

without faces for the grid

I have a result for 1900 faces

Tak

06:26

How?

also I tried that, I selected all vertices then selected the big face then hit P and choose by selected and how I have a big face

but there is a triangle kind of thing, not sure why it exisisted

lemon

Here is the way I did:

run the script

now edit mode, and alt+F

then x, limited dissolve

then x, faces only

alt+F again

then the knife project cut

Tak

okay

so after this step "then x, limited dissolve" there are only 304 faces

lemon

yes maybe but not the cuts corresponding to the grid (red lines in your image)

but yes... you can try the cut at this step, you are right

and that is giving 323 faces here... good !

but... why don't you use this grid directly, in fact ?

:S

Tak

06:42

what do you mean?

lemon

I mean, is the grid from the red line accurate enough ? (without doing all the previous parts and calculation)

Tak

no not really

I just created it so you understand what I wanted to happen

but I can do this accurately

lemon

ok so, to summarize:

the script

then edit mode and alt+F

then x, limited dissolve

and the knife project cut

is that ok for you ?

Tak

this is what I did:

1- run the script

2- edit mode then alt-F

3- x limited dissolve and set it to 1 degree

4- select all in edit mode and hit P separate by loose parts

5- delete all objects except for the contour one

so there are many faces in the feet and hands, there is no way I can combine them into one face?

lemon

06:57

I don't know how: again there is no hint to guess a calculation for these parts and not for the other ones

Tak

I thought there would be a way if faces are on the same plane they can be merged to fill the contour?

lemon

I don't know...

I need to work on my job now

I'll be back later if you need

Have a nice day

Tak

okay no worries, I followed the freestyle solution and it produced a good result :)

may be the steps can be converted into a python script :D
