hi

I would like to know if anyone knows how to make sums and reducions with auto fields for example if you have one square inside other and you want to remove the inner area how can we make it automatic?

Thanks

Miguel

I am not sure what you are looking for. Do you require help in 2D Autocad or 3D Autocad? Can you please attach drawing or some sample so that your problem can be easily undestood.
