Thanks for replying.Toan

I would like to take slightly different approach and create a family

I started creating family for this using family template Metric generic detail item line based. Stuck with the controlling array. How can I write formulae ? to control the spacing between dashed lines ?

Post your progress family here.

By the way, for what you show, a repeating detail component has more benefits.  One being you don't need any array and formula, just a symbol and spacing.  Another being you can select the entire string with TAB.  Lastly, you can draw it using pick line and set offset distance, very useful when you draw it following an existing path.

ROUNDUP behaves like ROUND, except that it always rounds a number up.

• If number digits is greater than 0 (zero), then number is rounded up to the specified number of decimal places.

• If number digits is 0, then number is rounded up to the nearest integer.

• If number digits is less than 0, then number is rounded up to the left of the decimal point.

Example:

rounds 3.2 up to zero decimal places is equal to 4

rounds 76.9 up to zero decimal places is equal to 77

ROUNDDOWN behaves like ROUND, except that it always rounds a number down.

• If number digits is greater than 0 (zero), then number is rounded down to the specified number of decimal places.

• If number digits is 0, then number is rounded down to the nearest integer.

• If number digits is less than 0, then number is rounded down to the left of the decimal point.

Example:

rounds 3.2 down to zero decimal places is equal to 3

rounds 76.9 up to zero decimal places is equal to 76
