Hi I’m trying to create a script that random rotates a selection of families. It works ok now - but I can’t figure out how to use negative values. An example - I would like the families to be random rotated minimum -10 degrees and maximum +10 degrees (theese numbers should be input), but I can’t figure out how to get negative numbers from Math.random. I’m not a programmer so it’s a lot of trail and error :slight_smile: Does anyone know how I can achive this? Thanks Jorgensen [Capture]

Generate random numbers between the domain 0-20 and minus 10 :wink:

Hi Thomas Thanks for the fast reply. The user should be able to enter different numbers, so the -10 and +10 varies. So the numbers could be -3 and +10 - is there a way to handle that? Thanks Jorgensen

input the domain 0-13 and minus 3 from the result.

This would be my solution, fairly simple but it should do the trick! [random list]

If you are trying to rotate families maybe you could add + 360 somewhere

Thanks Daan I think I need some more time to look at it - I also need to figure out how to use the families current rotation as reference. Jorgensen

take a look at this for that: [image] Get rotation or vector from placed families Packages I can query the XYZ values from an element easily with Dynamo but is it also possible to query the rotation of a placed family? what I mean by that is if I rotate a family in Revit can i query in Dynamo how much it was rotated (from its original position, not the previous position)? Any help would be appreciated. Thanks Martin

Clockwork has a couple nodes for normalizing values including one that will scale based on a given range, which is essentially what everyone is suggesting. [image]

Hi Nick Sorry for this noob question - but what is Clockwork?

Clockwork is one of the more popular custom packages (containing many useful custom nodes). You can download it through the package manager in Dynamo.
