Hello :) Thanks for using CADian. I""m sorry to tell you this but we do not support insert function for a wmf file. However, you can always insert a bmp, jpg, jpeg, tif, tiff, png, and emf file to CADian. maybe you can find a way to convert wmf file to those files above.. if that""s possible. Sorry for the inconvenience again. Please let us know if you have any other question about CADian. Thank you and have a good day.
