Good day! I have a problem with the make planar tool. when I select it, an unknown error is displayed. what could be the cause of this problem? SketchUp 2018

thanks for the wonderful plugin! very useful. I have a problem with the "extrude lines" tool. it does not work correctly. when I specify the height to which you want to squeeze a curved line, it does not squeeze it out, but simply moves it with copying. Do you know why this is so?
