1.1. Check your original drawing limits using the Check your original drawing limits using the LIMITS LIMITS command: they are from (0,0) to (a,b) command: they are from (0,0) to (a,b) (e.g. a = 12, b = 9) (e.g. a = 12, b = 9)

2.2. Check the dimensions (AxB) of your paper, in mm Check the dimensions (AxB) of your paper, in mm (e.g. 297x210 for A4 or 420x297 for A3 paper)(e.g. 297x210 for A4 or 420x297 for A3 paper)

3.3. What scale is to be used, 1:S What scale is to be used, 1:S (e.g. S = 50 for 1: 50 scale)(e.g. S = 50 for 1: 50 scale)

4.4. Approximately, the linetype scale should be (A/a)xSApproximately, the linetype scale should be (A/a)xS (e.g. 297/12x50). (e.g. 297/12x50). This is set in This is set in Format – Linetype ScaleFormat – Linetype Scale (for the (for the Global Global Scale FactorScale Factor))
