1. type dimension tool DIMENSION.
2. id primitive ID, unique within the document.
3. ticket logical clock.
4. partitionId partition ID it belongs to, null means no partition. Ignored for footprints.
5. groupId group ID: 0 no group, non-zero is the group flag, same flag means same group.
6. locked whether locked.
7. zIndex Z-axis height.
8. type dimension type: RADIUS radius, LENGTH length, ANGLE angle.
9. layerId layer.
10. unit unit: mm, cm, inch, mil.
11. strokeWidth line width.
12. precision precision.
13. textFollow whether text follows: 1 tool automatically decides text position, 0 always use the position of ATTR.
14. coords coordinate set X1 Y1 X2 Y2 X3 Y3 ... different dimension types define coordinates differently.

["ATTR", "e102", 0, "e101", 1, 200, 150, "VALUE", "1234mm", 0, 1, "SimSun", 50, 10, 0, 0, 0, 2, 15, 1, 1]

DIMENSION needs to be accompanied by an attribute with Key VALUE to express the text part of the dimension tool. EDA should ignore unnecessary properties such as whether to display Key and whether to display Value.

RADIUS Radius Tool

The first coordinate of the coordinate set is the endpoint touching the ARC, and the last coordinate is the default endpoint for displaying text, as shown below.

LENGTH Length Tool

The coordinate set only needs four points, as shown below.

ANGLE Angle Tool

The coordinate set needs 3 points, as shown below.
