## Re: Orientation of polygons

But there
is one polygon with shape of letter L, which gives me a lot of problems:
the shape of polygon is something like this:
1--2
| \
| \
| 3-------4
| |
| |
6-------------5
Sorry about the late reply. I've been out of town for a week and a half.

The problem is that the above polygon is 'concave' which gives FSDS
trouble. If you split it into two polygons, one using points 1,2,3,6
and the other using points 6,3,4,5 you should have no trouble.

Hi Louis,
I have guessed that You have been on a vacation. Hope You had great time ))
About my problem. I have solved the problem exactly as You said but will it be
possible to make polygon someday in one piece? It is interesting that the
problem with the polygon I am describing was solved by splitting the polygon in
two pieces, whereas I have made a tube with 3 sections with this shape. In FSDS
polgon of the last section shows points 2 and 4 connected but in FS2000 the
polygon is correctly displayed.
And still it is strange, how FSDS solid display works. I made the terminal
building, which shows in FS perfectly, but solid display in FSDS... It is
difficult to say that the object resembles to a terminal building (OK, It is
really difficult building).

Goran
