Hi Neil, sure give this one a try:

script: if ( moi.drawingAids.straightSnapAngle == 0.0 ) { moi.drawingAids.straightSnapAngle = 90.0; moi.drawingAids.straightSnapEnableVertical = true; moi.drawingAids.straightSnapEnableTangent = true; moi.drawingAids.straightSnapEnablePerpendicular = true; moi.drawingAids.straightSnapActivateDistance = 6; moi.drawingAids.straightSnapKeepActiveDistance = 12; } else { moi.drawingAids.straightSnapAngle = 0.0; moi.drawingAids.straightSnapEnableVertical = false; moi.drawingAids.straightSnapEnableTangent = false; moi.drawingAids.straightSnapEnablePerpendicular = false; moi.drawingAids.straightSnapActivateDistance = 1000; moi.drawingAids.straightSnapKeepActiveDistance = 1000; }
