The default font heights etc. in the program are set to 1/1 ratio. We send it with a scale like /50. If you take the drawing as 1/50 scale, you should send it to the plotter as 1/1. However, since the default values in the program are 1/1, it would be better to import the drawing as 1/1 in ideCAD so that it does not interfere with creating new objects.
