Applied Parameters: DimensionKind = ANGULAR

Summary

This command is used to place an Angular Dimension object onto the active document. An angular dimension is a group design object. It allows for the dimensioning of angular distances.

For detailed information about this object type, see Angular Dimension.

Access

This command can be accessed from the PCB Editor by:

Choosing the Place » Dimension » Angular command from the main menus.
Clicking the button on the Place Dimension drop-down () of the Utilities toolbar.

Use

After launching the command, the cursor will change to a cross-hair and you will enter dimension placement mode. Placement is made by performing the following sequence of actions:

Position the cursor over the first reference object and click or press Enter to anchor the first dimension reference (the inside reference).
Move the cursor to the next required position associated with the first object being dimensioned and click or press Enter to anchor the second dimension reference (the outside reference).
Position the cursor over the second reference object and click or press Enter to anchor the third dimension reference (the inside reference).
Move the cursor to the next required position associated with the second object being dimensioned and click or press Enter to anchor the fourth dimension reference (the outside reference).
Place the dimension text for the angle as desired and then click or press Enter to complete placement.
Continue placing further angular dimensions, or right-click or press Esc to exit placement mode.

When dimensioning an object, anchor points become available to you, highlighting where the dimension can be attached. The point nearest the cursor will be the one used, and where the dimension will attach if you proceed to click, or press Enter.

Additional actions that can be performed during placement are:

Press the + and - keys (on the numeric keypad) to cycle forward and backward through all visible layers in the design respectively – to change placement layer quickly.
Press the Tab key to access the Angular Dimension dialog, from where properties for the dimension can be changed on-the-fly.

Tips

While attributes can be modified during placement (Tab to bring up associated properties dialog), bear in mind that these will become the default settings for further placement unless the Permanent option on the PCB Editor – Defaults page of the Preferences dialog is enabled. When this option is enabled, changes made will affect only the object being placed and subsequent objects placed during the same placement session.
Angular dimensions are group objects consisting of text and track segments. They can be converted to their set of primitive objects by choosing Tools » Convert » Explode Dimension to Free Primitives from the main menus. Once exploded, a dimension object can no longer be manipulated as a group object.

Place Baseline Dimension

Applied Parameters: DimensionKind = BASELINE

Summary

This command is used to place a Baseline Dimension object onto the active document. A baseline dimension is a group design object. It allows for the dimensioning of a linear distance of a collection of references, relative to a single base reference. The first point chosen is the 'base'. All subsequent points are relative to this first point. The dimension value in each case is therefore the distance between each reference point and the 'base', measured in the default units. The references may be objects (tracks, arcs, pads, vias, text, fills, polygons or components) or points in free space.

For detailed information about this object type, see Baseline Dimension.

Access

This command can be accessed from the PCB Editor by:

Choosing the Place » Dimension » Baseline command from the main menus.
Clicking the button on the Place Dimension drop-down () of the Utilities toolbar.

Use

Position the cursor and click or press Enter to anchor the dimension start point (this is the first reference point or 'base').
Move the cursor to the required end point and click or press Enter to anchor the dimension end point (this is the second reference point).
The text can now be initially positioned. Click or press Enter when the text is in the desired position to effect placement.
Move the cursor to subsequent reference points and click or press Enter twice to effect placement (first click to anchor to a reference and second click after positioning the text).
When all required references in the baseline dimension have been covered, right-click or press Esc to exit placement mode.

Additional actions that can be performed during placement are:

Press the + and - keys (on the numeric keypad) to cycle forward and backward through all visible layers in the design respectively – to change placement layer quickly.
Press Spacebar to rotate the dimension anti-clockwise or Shift+Spacebar for clockwise rotation. Rotation is in accordance with the value for the Rotation Step, defined on the PCB Editor – General page of the Preferences dialog.
Press the Tab key to access the Baseline Dimension dialog, from where properties for the dimension can be changed on-the-fly.

Tips

While attributes can be modified during placement (Tab to bring up associated properties dialog), bear in mind that these will become the default settings for further placement unless the Permanent option on the PCB Editor – Defaults page of the Preferences dialog is enabled. When this option is enabled, changes made will affect only the object being placed and subsequent objects placed during the same placement session.
