Hello,

Thank you very much for the angle measurer. @lassoan, is there a way to define the module for several rulers with a chosing panel to select the rulers ? I have multiple rulers for a project and I would require to be able to choose the rulers when needed instead of deleting every rulers after measuring the angle.

Thanks in advance,  
Theophile
