I have no idea if this can even be done; I have an SVG file in Illustrator, and it is fairly large. I need it to be about 5% of what it is now. I have tried holding Shift and dragging to the correct size and it's always distorted.
I have tried setting the percentages through image size, every time it is distorted. What are my options?
Firstly How complicated, the vector image is? What is the canvas size? The file size?
Check the vector point positions before and after scaling, by Alt + ctrl + Y (Pixel View) in view menu.(on/off). (I think this will clear your problem).
Check if your system is able to handle the amount of data that it is processing?
