I know Acad is super-accurate, but sometimes this can be as much a curse as a blessing.
I'd like a command, something like FLATTEN that would round any values up or down to a specific number of decimal places. I'm not talking about DDUNITS. I mean x,y,z and rotational values at least. Preferably any editable numerical field.
For example, 90.00000001 degrees would become 90 degrees.
or, 3.2467545493 could become 3.247 or 3.25 or 3.2 or 3
Things like fillets, intersections and many others rely on objects being perfectly aligned. I'm usually working with one to three decimal points of accuracy. Errors like this don't even show up until you change up the DDUNITS value.
I work in construction, everything is in millimetres. A tool such as this would save an enormous amount of my time. Minor errors in field values can occur very easily, especially when dealing with inexperienced users or non-native DWGs. I like to think I'm being careful to avoid such problems, but even I mess up from time to time. Then, it's a lot of work tracking down and correcting errors. They can very quickly compund.
