What is the spacing from object line to first dimension line?

The spacing from the object line to the first dimension line is typically set to ensure clarity and readability in technical drawings. Standard practice often recommends a gap of about 3-5 mm (1/8 to 1/4 inch), but this can vary depending on the specific drafting standards being followed, such as ANSI or ISO guidelines. It's important to maintain consistent spacing throughout the drawing for uniformity. Always refer to the relevant drafting standards for precise requirements.
