EXTERNAL

The EXTERNAL style is a variant on the Dimline style. For Diameter dimensions, two short radial lines are drawn outwards from the circumference with terminators on the circumference. If the text radial position lies outside the circumference, then one line is extended to the text offset position (with optional text underlining).

For Radius dimensions with EXTERNAL style the appearance depends on the text radial position. If it lies inside the circumference, then a single short radial line is drawn outwards from the circumference with a terminator on the circumference.

If the text radial position lies outside the circumference, then the dimension is drawn exactly the same as in the DIMLINE style except that the terminator direction is flipped to be outside the dimension line. The example illustrates the EXTERNAL style (with DTUL ON).
