@opPattern: INVALID_INPUT

nir_naron

Trying to duplicate a user-selected line. No idea why these two Featurescripts attached below aren't working. Out of ideas. @NeilCooke HELP!
Also, side questions:1) What's the best way to have the pattern be perpendicular to the line? Currently they're in the same direction. I was hoping to be able to go <evvLine.direction.normal> though it seems like that's not the way.2) How do I get <selctedLine>'s start-point and end-point? The start-point is <evvLine.origin> but I'm not sure about the end-point.Thanks!
