I need to trace a drawing to convert it to AS. I know the dimensions of come lines to be traced. How can I set the scale so the lines I trace are accurate to the scale I need?
Your question is unclear, which may reflect your quandary at the moment. First you have to decide what you mean by "scale that you need". Probably the most common choice there is the size whee your material fills the drawing space without being crowded. Is that your choice?
I don't watch this that closely, so other feel free to respond to any more infor provided.
