PCB Layout CAD : Draw
Dimension
There are the following types of Dimensions.
In addition, for components, there is an auto dimension creation function for automatically creating Pad Dimensions, Assembly Dimensions, etc.
| Line Dimension | Rectangle Dimension | Circle Dimension | Pad Dimension |
| Draws a Line Dimension. Click a line. |
Draws a Rectangle Dimension. Click a side of a rectangle. |
Draws the Diameter and Radius Dimension for Circles and Arcs. Click a circle. |
Draws the Pad Diameter Dimension. Click a pad. |

| 2 Point Distance Dimension | Free Dimension | Leader Line | Angular Dimension |
| Draws a Dimension for measuring the distance between two objects. |
Draws a Dimension for two arbitrary coordinates. Click two points for the distance you want to measure. |
Draws a Leader Line. Click a start point and end point for the Leader Line that you want. |

In addition to the basic dimensions explained here, confirm the functions for "Create Component Dimension Automatically", which executes auto creation based on the Component Pad and Assembly, and for "Create Board Outline Dimension Automatically", which executes auto creation based on the Board Outline.
There are several other ways to perform this. Refer to About Executing Menus.
When [Update Component/Replace Component] is executed for a dimension that was created for a component on a PCB design, the creation target will be reset and it will be deleted.
The following will explain each operation for drawing Dimensions.
