The Footprint Draw Menu

The footprint editor Draw menu presents options for drawing graphical primitives and text, and manipulating selected objects. The Draw menu options include:

Primitive > Arc

This option, also available from the Footprint Draw toolbar , initiates creation of an arc. To draw an arc, click the footprint editor grid at the two points that will determine the arc’s ends, and then drag the arc to the desired radius.

Once you have created an arc, you can adjust its radius or move its endpoints by clicking the arc to select it, and dragging the appropriate handle.

Primitive > Circle

This option, also available from the Footprint Draw toolbar , initiates creation of a circle. To draw a circle, click the footprint editor grid to select a center point, and then drag the circle to the desired diameter.

Once you have created a circle, you can adjust its diameter in either of two ways:

• Click the circle to select it, and then drag one of its handles.

• Double-click the circle to open its Properties dialog, type a new value for the Radius parameter, and then click OK.

Primitive > Line

This option, also available from the Footprint Draw toolbar , initiates creation of a polyline with one or more segments. To draw a line:

1. Click the footprint editor grid where you want the line to start, and then click at one or more points to continue the line.

2. To complete the line, do one of the following after defining its final segment:

• Press SPACE.

• Right-click, and then click Finish.

After you have completed a line, you can change the endpoints of its segments as follows:

• Select the line and drag the appropriate handle(s).

• Double-click the line to open its Properties dialog, type new values for the parameters you want to change, and click OK.

Primitive > Rectangle

This option, also available from the Footprint Draw toolbar , initiates creation of a rectangle. To create a rectangle, click the editor grid to specify the position of one corner, and then drag the rectangle to the desired size.

Once you have drawn a rectangle, you can edit its height and width, the position of its center, and its angle (its rotation, in degrees, relative the handles of its bounding box) as follows:

• Click the rectangle, and then edit its properties in the Properties window.

• Double-click the rectangle, and then edit its properties in the Properties dialog box.

Primitive > Polygon

This option, also available from the Footprint Draw toolbar , initiates creation of a polygon. To create a polygon:

1. Click the footprint editor grid to specify the position of one vertex, and then click wherever you want to place additional vertices.

2. To complete a polygon, specify the position of its final vertex, and then do either of the following:

• Press SPACE.

• Right-click, and then click Finish.

Once you have drawn a rectangle, you can edit its vertex positions and other properties, including its fill style, as follows:

• Click the rectangle, and then edit its properties in the Properties window.

• Double-click the rectangle, and then edit its properties in the Properties dialog box.

Primitive > Text

This option, also available from the Footprint Draw toolbar , adds to the footprint an editable “Default text” label in 12-point Arial. To edit the default text string immediately after placement, type the text you want, and then press ENTER or click elsewhere in the editor grid.

To change just the text of an existing label:

1. Click the label.

2. Click the label again to open its text for editing.

3. Type the desired text.

4. Press ENTER or click elsewhere in the editor grid.

To change other properties of a label, including its font and size:

1. Click the label and view its properties in the Properties window, or double-click the label and view its properties in the Properties dialog.

2. Click in the Value cell for the property you want to modify.

3. Modify the value.

4. Click OK, or click in another Value cell to commit the change and keep editing values.

Void > Circle

Create a void, or remove material from an object, in the shape of a circle, rectangle, polygon, or line using the Void > Circle command. One object can have multiple voids, but each void can only be associated with one “parent” object.

Void > Line

Create a void, or remove material from an object, in the shape of a circle, rectangle, polygon, or line using the Void > Line command. One object can have multiple voids, but each void can only be associated with one “parent” object.

Void > Rectangle

Create a void, or remove material from an object, in the shape of a circle, rectangle, polygon, or line using the Void > Rectangle command. One object can have multiple voids, but each void can only be associated with one “parent” object.

Void > Polygon

Create a void, or remove material from an object, in the shape of a circle, rectangle, polygon, or line using the Void > Polygon command. One object can have multiple voids, but each void can only be associated with one “parent” object.

Port > Create

Use the Port > Create command to create a port.

Port > Remove

Use the Port > Remove command to remove a port.

Pin

This option, also available from the Footprint Draw toolbar , initiates placement of a footprint pin with a default stem length of 10. You can rotate a pin once you’ve started to place it by iteratively pressing R until the pin is oriented to your liking. Click in the editor grid to finish placing the pin.

Via

This option, also available from the Footprint Draw toolbar , initiates placement of a through hole (via) of the default size (1mm).

Handle

This option, also available from the Footprint Draw toolbar, , allows you to create an explicit footprint handle that can later be used to resize or reshape the footprint based on the handle’s reshaping rules.

3D Structure

Opens a submenu that allows you to create and perform operations on a 3D structure in the Drawing Region.

Coordinate System

Opens a submenu that allows you to create and perform operations on a coordinate system in the Drawing Region manage. For more information see Coordinate Systems.

Rotate

This option, also available from the Footprint Draw menu or by pressing CTRL+R on the keyboard, rotates a selected object or group of objects 90° to the left.

Flip Vertical

This option, also available from the Footprint Draw menu , flips a selected object about the X axis.

Flip Horizontal

This option, also available from the Footprint Draw menu , flips a selected object about the Y axis.

Align

Align selected objects in the Drawing Region.

Position Relative

When a relative coordinate system (CS) and an object independent of that CS are selected, the “Draw > Position Relative” command will position the CS relative to that object.

Clear Relative Position

When a relative coordinate system (CS) and an object are selected, the “Draw > Clear Position Relative” command will position the CS unrelative to that object.

Duplicate

Duplicate a selected object in the Drawing Region.

Defeature

Defeature and repair selected objects in the Drawing Region.

Stitch Lines

Stitch together connected/crossing lines into polygons and lines.
