3D Shell - Side Datum Line
When you need to draw a side groove, you need this side reference line for positioning.
Entrance: Entrance: Top Menu - Place - 3D Shell - Side Datum Line
Side reference lines are only allowed to be set on the 3D shell border layer.
How to use:
On the side of the shell that needs to be grooved, when determining the top view of the board, the frame line segment corresponding to the side
Place the side reference line, parallel to the corresponding border line segment, do not overlap with the border line segment, and need to be placed outside
Then place the side grooving area on the outside. The distance of the side pocket area from the baseline is the height of the pocket from the bottom. As shown below: The height of B is equal to the distance of A.
The side reference line can also be in any direction, and the side groove area will be cut perpendicular to the side reference line.
