I have tried to do this using both menu commands and icons but with the same result: I click on the first circle and then the command line indicates to click on the 2nd circle or arc. Nothing appears to happen when I do this and the command line continues to show that I should click on the 2nd arc or circle.
I am running QCAD v22.214.171.124 in Windows XP. I have not done much with QCAD before now and shall be grateful for any advice.
Many thanks in advance.
