I made drawings on big area and not mentioned real size of movements of the gondola until I needed to draw on A4 paper. And then I set page size to 210x297 mm, set frame to this size and clicked "draw outline selected" machine goes almost right 210 mm width. BUT height of outline is ~250 mm instead of 297. Why I have result like that and could it be resolved not with setting different sizes that can be picked up experimental way instead of being real measurements that exactly match A4 or anything else size?
P.S sorry for just complaining here and thanks for help!
