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 🙂 Does anyone know how I can achive this? Thanks Jorgensen ![Capture](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/7/57980c9aeb91961411b90c65cb6e6480ab87d18c.jpeg) ---

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

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](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/d/1d6d5a1011c36627a4bb2aab4396b64873289091.png) ---

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: > [@Get rotation or vector from placed families](https://forum.dynamobim.com/t/get-rotation-or-vector-from-placed-families/1004): > > 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](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/c/bc97a7d7c2839537c94e0e3cdff82ebc20d4b3eb.png) ---

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. ---

Yes, you could see Clockwork as downloadable content with a lot of extra nodes to use in your Dynamo Environment! ---

You could consider using the OOTB node _Math.RemapRange_ ![remap](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/1/a17677d594ce2e998af3113974389677bd9fc8e6.png)
