Hi Here, I have just down loaded the 2020 version. I have used the 2018 for many years (which is now uninstalled). I simply want to draw a straight line of 50mm. I type 50 press enter, It draws the line correctly. Then I want to draw another line of 50mm at 90 degrees. I type 50 press enter. It draws a line 5050 long and so on. The "50" does not reset in the command window. It keeps on adding 5050505050 etc. Why is this?
