Hi
I am modeling a fire protection system for a hospital, how I can place sprinklers automatically so that distance between 2 sprinklers cannot exceed 15 feet
Hello @engali1986ac and welcome to the forum 
yes its possible, could you show what you have tried so far in dynamo ?
and take a look here as well…How to get help on the Dynamo forums
@sovitek Thanks for reply, I didnot do it yet, I have a little knowledge in using dynamo, can you tell me where to find a tutorial about this topic
then i first wanna go trough primer, so you know the basic stuff, and search the forum here for similar topics, and if you go stuck, then just show us where and we will be happy to help…if we can ;)..
…Note that is will be slightly advanced, so you might want to start with some simpler tasks until you get the basics mastered.
Quite a few rules to define in your application. (And I believe there are numerous commercial applications that may be worth considering )
