I have one question: when I make block and want to insert it in a drawing with the same characteristics as the original one where the block is made (measurement units millimeters, scale 1:50), AutoCAD automatically scales it so it is much smaller than the original - it is scaled with factor 0.0394...and a field in a dialog box where this factor is shown isn't available for overwriting. It is so annoying that each time when inserting the block, I have to scale it manually (1/0.0394=25) in order to get the real measures. How can I solve this problem? tnx ;-)
