How to achieve the same proportion of appearance patent applications? I don't quite understand this piece of music. When revising, the proportion should be consistent. Does it mean that the length, width and height of the seven pieces are the same? Indicates that the proportion of products in the view should be consistent, such as a box, the height in the main view should be consistent with the height in the left and right views, the width in the main view should be consistent with the width in the pitch view, and the thickness in the pitch view should be consistent with the box thickness reflected in the left and right views. If it is a photo view, the scale must be adjusted appropriately after shooting. If it is a drawing view, the size can be guaranteed to be the same when drawing.
