Angle between 0 magnitude vector and other error

[charliebrookerBH]

Hi @chriswmackey and team,

Big fan of your tools and massively appreciate the work you've put into them. I'm a python beginner and I'm trying to start going beyond using the provided components and start building some of my own using the available codebase.

A problem I've come up against is combining the fin_pattern method with the sky dome vectors. As the sky dome has a 0,0,1 vector for the top most patch when I try and input the sky dome vectors as view_vectors in fin_pattern it then throws a DivideByZeroException for the 2D angle method.

Is there a solution to this?

In my use case, having angle return 0 when the DivideByZeroException error occurs would be an ideal solution, but understand this might not be appropriate for all operations.

Thanks! Charlie

PS I haven't assigned, labelled, or any of that stuff, not sure what your protocol is for this.

Hi @charliebrookerBH - Thank you for sharing the code and thank you for the kind words. The better place to ask this question is the forum under the scripting category: https://discourse.ladybug.tools/c/scripting/28

Thanks Mostapha! Still getting my head around this.
