The standard unit used by SolidWorks is the meter. Fair enouh.

What if the user needs to design a microchip measured in nanometers?

Or a very large space ship or planetary system measured in tens of kilometers?

This should be doable, correct?

Notice that all I need is to move the decimal point around, I am not referring to using inches/yards, etc.

Can we work in user space coordinates?

TIA
