Re: [Therion] Overlaying xvi file and map background as the same scale

Hi Martin, Thanks for your answer. I want overlay .xvi file and image file for two reasons. 1) I can see if the old survey what I have is correctly drawn, so if stations of .xvi and image are on the same position. 2) This cave is still in exploration. When I will add new stations, how I’ll draw them if the xvi and the first part of the cave are not on the same scale ?
