Hello

I've made a few export test to clearly undestand export options.

Maybe my tests may help beginer to understand (or maybe I misunderstood how Moi work, so, do not hesitate to correct me.)

=======

1) Angle

=======

First I created a circle and convert it to a surface (using planar tool) in order to test what happends when I change "angle" value (in the "meshing options" windows).

For those who don't like mathematic : Complete circle = 360°

When I choose 55° I get 7 polygons

360°/7=51,43°

55° is rounded to 51,43°.

It seems logic

When I choose 54° I get 8 polygons.

360°/8=45°

54° is rounded to 45°

In this case, I expected 54° to be rounded to 51,3° (which is closer than 45°)

I made a few other test :

76° is rounded to 72° (360°/5)

75° is rounded to 60° (360°/6) but is closer to 72° (360°/5)

26° is rounded to 24° (360°/15)

25° is rounded to 22,5° (360°/16) but is closer to 24° (360°/15)

So, my conclusion is :

mesh exported angle = ("angle" minus approximatively 5%) rounded to the inferior value.

Where "angle" represent value in the "meshing options" windows.

When trying to get precise polygon number this may help.

But of course 99,99% users probably don't care (I know, I'm pernickety man)

2) divide larger than

=======

2.1)-plane-

I created 4 rectangular plane :

10x1cm

10x0.6cm

10x0.2cm

10x0,03cm

Then I export using "Divide larger than" set to "1".

As you can see :

in the first three rectangle, rectangles are divided in polygon having width inferior to 1

in the fourth rectangle, rectangle are divided in polygons having width equal to 1

I didn't undestand why all the polygon have not the same width. But once more, I'm probably the only one intersted in such pernickety details.

2.2)-curved-

I created a cylinder

And I make test to understand "curved"

first I only choose a value for angle

then I add a value "Divide larger than"/"curve"

then I add a value "Divide larger than"/"plane" (polygons don't seem regularly created)

then I add a value "Divide larger than"/"all"

When using 54°, polygons don't seem regularly created for both plan and curve :

I don't know if this will interrest anyone, but my objective is reached, I now understand mesh export option.
