| You can post here your scripts and utilities that you made and used to work with SpaceEngine.
Some links to other tools which I consider useful and interesting.

I'm starting ...
AsterRingMaker
This is a .bat script I use a to make asteroid rings. Rings with 2,000 objects take on my computer about 6 minutes.
It's a bit complicated, because for each ring a number of parameters have to be manually changed.
Furthermore, an external program to generate floating-point numbers is needed because an MS-Dos batch file can not.
I use a Lua script for it.
If you have Lua on your computer, you can use the attached script.
Otherwise you need any other calculating program that prints its results to the console.
You must then replace 'Lua lcalc.lua' in 'AsterRingMaker.bat' with path and name of your Calculator.
It would be best, of course, if someone would create a real program with an input mask.
I also attach a sample script that I created with this.

| Quote abrasax (  ) I'll try to make it. It will be in flash and ugly, but it will have a UI.
Good 
Quote abrasax ( ) Is there something other than the stuff in your batch file I should add for parameters?
For me the whole thing, as it is sufficient.
Quote abrasax ( ) Is there a need to create multiple rings at the same time?
If you can do it, nothing speaks against it.
Quote abrasax ( ) Somehow randomize the limits?
The values are randomized within the limits.
Quote abrasax ( ) Could you go into it in a bit more detail?
Not really.

Test it. I don't even know where to put the file it outputs :D
Edit:
No need to test it it doesn't work :D. Give me a minute...
question: (1+%random%)/32768 is this just random from 0 to 1? and why 32760 for argofpericen?

| Assuming 32760 was a typo it should work now the same as your script.
I hope you don't mind I put all your sample values as default values.
Please test it and give me suggestions to make it better.

%RANDOM% is an environment variable in MS-Dos batch files that provides a random value between 0 and 32767.
In order to provide a value between 0 and 1; 1 must be added, and the result must be divided by 32768.
But this is only possible with an additional program that can process floating point numbers.
32760 is a typo.

| So can you test it and let me know if something needs to be fixed or changed or added?

Very good. It works. And it is much faster than the .bat program. 
Is there any source code?

Do you mean AsterRingMaker.bat? Not Lua uses this program, but this program uses the script lcalc.lua when it is in the same directory. And of course, Lua must be installed in the system.

How do I install Lua to work with your script?

Here you can download Lua.
But you no longer need my script, you can use the program of abrasax. For this you do not need Lua.

| Quote LookAtDatDakka ( ) what about generating object other than asteroids
In principle, it is possible to create comets with this program.
Here I have created a few comets for Toliman A (Alf Cen A).
Maybe a few too many.
I used these settings for it.
When the script is created, you have to open it in a text editor; and with Replace all 'Asteroid "C' replace by 'Comet "C'.
It should look something like this:
Code Comet "C 1"
{
ParentBody "Toliman A"
Class "Asteroid"
Radius 7.2117724805139005
Orbit
{
Epoch 2457395.5
SemiMajorAxis 2.180736281396821
Eccentricity 0.31757065607234836
Inclination 102.95168509706855
AscendingNode 172.88731696084142
ArgOfPericen 133.31986024975777
MeanAnomaly 0
RefPlane "Ecliptic"
}
}
Comet "C 2"
{
...

| To jump in on the asteroid fest, I whipped up my own version of Jack's script in Python with a few more bells and whistles. You can find my version of the script here:
AsterRingMaker.py
I added a few more parameters, including the ability to set some or all of your asteroids rotating - in real life asteroids are not tide-locked with the Sun. I also used a Gaussian probability distribution for most of the value ranges instead of a uniform one, though I left a bit of code in there for people who want to use uniform distribution.
Hope you don't mind, Jack. I'd actually been thinking of making something like this for some time now, you gave me the kick in the pants I needed.
