Objects moving when exporting from Artboard to SVG
Hi, I am very new to Illustrator and am using it to make scientific figures for my thesis. When I exported my artboard to SVG and placed it in Word, objects on the artboard started moving. I haven't had this problem until now and I did change the artboard size for this figure. I saw a post that said to make sure the x and y values for the artboard were whole numbers, which I did and it's still happening! Any ideas, please?
