Hello all, I have been reading about how to import a segment file or a .dat file in Pointwise, and I have always encountered the following answer:

c.....nmax is the number of segments
c.....ni(n) is the number of points on segment n
c.....imax is the number of points
integer nmax
integer ni(nmax)
real x(imax), y(imax), z(imax)
do n = 1, nmax
write(1,*) ni(n)
do i = 1, ni(n)
write(1,*) x(i,n), y(i,n), z(i,n)
end do
end do

Or variations of it. The point is, can anyone actually give me a simple .dat file or segment file with one segment and 3 points so i can load it on Pointwise?

I have tried to implement the pseudo-code but I believe I must be doing something very wrong. I use a spreadsheet to implement the pseudo-code but Pointwise never imports my .dat files.

Best regards

Here is a segment file that imports a triangle:

4
0 0 0
0 1 0
1 0 0
0 0 0

And with multiple segs in one file. This defines a triangle and a square.

4
1 1 0
1 2 0
2 1 0
1 1 0
5
2 1 0
2 3 0
4 3 0
4 1 0
2 1 0

Hello,

I have run on several answers to my question below.
How to import data from a .dat or .txt file? File contains x,y,z coordinate of a point.

The answer was always:
c.....nmax is the number of segments
c.....ni(n) is the number of points on segment n
c.....imax is the number of points
integer nmax
integer ni(nmax)...

Can someone explain how to use it on .dat or .txt file?

Regards, Petar

There is an example of a multiple segment file in post #3 above.

Another way of defining it is:

N1
x1 y1 z1
x2 y2 z2
 ...
xN1 yN1 zN1
N2
x1 y1 z1
x2 y2 z2
 ...
xN2 yN2 zN2
<repeat>

Where,
N1 is number of points in segment 1.
N2 is number of points in segment 2.
xn yn zn is the coordinates of segment point n.
