People, If I produce a new drawing on an A4 page with Display and User units in mm with a scaling factor of 1.0, I can draw a rectangle of XxY and when I use the Visualise->Measure Path Extension with a Scale Factor of 100 and Length Unit in m - I get exactly the right dimensions for the rectangle for its perimeter length and area - all good! However, I have imported a surveyor's map from a PDF file into SVG and I need to be able to draw rectangles on it as above in mm (like my test) that will correspond to m in the real world but the drawing is on an A1 page and the Display and User Units are in px and I have tried everything I can think of and Googled a lot but I can't do what I was able to do with my little test case. So: How can I convert the drawing to be on an A4 page with mm units so the mm correspond to m and the Measure Path Extension will give me the correct result in m and sqm? The original PDF says the scale was 1:300. Thanks, Phil. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil@...2067...
