This command is used to place a Bending Line across an existing board region within the current design. A bending line is a drawn PCB object that defines how a flexible board should be bent. Bending lines can be placed across a Board Region that has been assigned a Layer Stack with the Flex option enabled – that is, the particular board region has been configured as flexible.
A bending line defines where on the surface of the flex region the bend is to take place. It also defines the angle and radius of the bend and the width of the strip of board surface that is being bent. When the PCB editor is in 3D Layout mode, the bends can be displayed in their progressively folded state, providing a real-world look at the rigid-flex design.
For detailed information about this object type, see Bending Line.
This command can be accessed from the PCB Editor when configured in Board Planning Mode by choosing the Place » Define Bending Line command from the main menus, right-clicking in the design space then selecting Place » Define Bending Line, or select from the Active Bar.
After launching the command, the cursor will change to a cross-hair and you will enter bending line placement mode. Placement is made by performing the following sequence of actions:
- Click, or press Enter, inside the board region where the bending line is to be placed. One end of the line will attach to the edge of the region closest to the click location, the other end will attach to the directly opposite edge.
- Move the cursor to position the other end of the bending line, then click or press Enter to place it. The bending line will remain yellow if the location is valid.
- Continue placing further bending lines, or right-click, or press Esc, to exit placement mode.
When a board region is set to use a Flex layer stack, a bending line is automatically added, vertically down its geometric center. Remove, or reposition and configure this bending line as required.
