На этой странице документации упоминается Altium NEXUS/NEXUS Client (часть развернутого решения NEXUS), поддержка которого прекращена. Все ваши потребности в проектировании печатных плат, управлении данными и совместной работе теперь могут быть реализованы с помощью Altium Designer (с подпиской Altium Designer Enterprise) и подключенного рабочего пространства Altium 365 Workspace.

PCB Editor object properties are definable options that specify the visual style, content and behavior of the placed object. The property settings for each type of object are defined in two different ways:
Pre-placement settings – most Linear Dimension object properties, or those that can logically be pre-defined, are available as editable default settings on the PCB Editor - Defaults page
of the Preferences dialog (accessed from the button at the top-right
of the design space). Select the object in the Primitive List to reveal its options on the right.
Post-placement settings – all Linear Dimension object properties are available for editing in the Linear Dimension dialog and the Properties panel when a placed Linear
Dimension is selected in the design space.
If the Double Click Runs Interactive Properties option is disabled (default) on the PCB Editor - Defaults page of the Preferences dialog, when the primitive is double-clicked or you right-click
on a selected primitive then choose Properties, the dialog will open. When the Double Click Runs Interactive Properties option is enabled, the Properties panel will open.
While the options are the same in the dialog and the panel, the order and placement of the options may differ slightly.
Width - the current dimension line width.
Width - the current width for the dimension extension lines.
Gap - the distance between a dimension extension line and the object being dimensioned.
Offset - the current line offset with respect to the dimension extension line.
Text Gap - the current gap to the left and right of the dimension value text.
Arrow Size - the current arrowhead size. The size is measured as the distance between the arrow tip and the end of the arrow 'legs'.
Arrow Length - the current arrow length. Note that the value entered into this field is applied only when the Arrow Position (in the Properties region) is set to Outside.
Layer - the layer to which the dimension is currently assigned. Dimensions can be assigned to any available layer. Use the drop-down to select a different layer.
Text Position - the current position of the dimension text. Use the associated drop-down list to choose one of the following options:
Automatic - the dimension text will be placed in the most appropriate location with respect to the dimension so that the text itself is always readable.
Aligned - Center - the dimension text will be aligned to the center of the dimension line.
Aligned - Top - the dimension text will be aligned above the dimension line and centered.
Aligned - Bottom - the dimension text will be aligned below the dimension line and centered.
Aligned - Right - the dimension text will be aligned to the right of the dimension line (outside of the extension line).
Aligned - Left - the dimension text will be aligned to the left of the dimension line (outside of the extension line).
Aligned - Inside Right - the dimension text will be aligned to the right of the dimension line (inside the extension line).
Aligned - Inside Left - the dimension text will be aligned to the left of the dimension line (inside the extension line).
Unidirectional - the dimension text will be aligned to the center of the dimension line but will remain horizontal regardless of the dimension alignment angle.
Manual - the dimension text will be available for manual placement directly in the design space.
Arrow Position - the current position of the dimension arrows. The available options are:
Inside - arrows will be positioned inside the dimension's extension lines (pointing outwards).
Outside - arrows will be positioned outside the dimension's extension lines (pointing inwards).
Text Height - the current height of the dimension text characters. The character width used to display or print the text is automatically proportioned to this height. A minimum height of 36mil (0.9mm) will
allow the text to be legibly photo-plotted.
Rotation - enter the number of degrees you'd like the dimension to rotate if desired.
TrueType - use this field to choose the required TrueType font. The drop-down list is populated with TrueType and OpenType (a superset of TrueType) fonts found in the \Windows\Fonts folder. Note, the
list will only include entries for detected (and uniquely named) root fonts. Use the B (bold)and I (Italic) options to add emphasis to the text.
Font - use this field to choose the required Stroke font. Available options are:
Default - a simple vector font that supports pen plotting and vector photo-plotting.
Serif - a more complex font that will slow down vector output generation, such as Gerber.
Sans Serif- a more complex font that will slow down vector output generation, such as Gerber.
Stroke-based fonts are built into the software and cannot be changed. All three fonts have the full IBM extended ASCII character set that supports English and other European languages.
Stroke Width - displays the current stroke width.
Primary Units - the current unit that is selected for the calculation and display of the dimension value. Choose either Mils, Millimeters, Inches, Centimeters, or Automatic.
The Automatic setting follows the actual measurement unit employed for the board as determined by the Units setting in the Other region of the Properties panel in Board mode.
Value Precision - the current setting for the number of decimal places to the right of the decimal point for which the dimension will be displayed.
Format - the current setting for the format of the dimension text. Use the associated drop-down to change the format as required. The options listed will depend on the chosen Unit and present based
on the actual value for the current dimension. In generic terms, the available options are:
None - no dimension text is displayed.
Value Only - no units are displayed, only the dimension value (e.g., 600.00).
Value and Unit - units are displayed after the dimension value (e.g., 600.00mil).
Value and Bracketed Unit - units are displayed in brackets after the dimension value (e.g., 600.00 (mil)).
Prefix - the current prefix to the dimension value.
Suffix - the current suffix to the dimension value.
Sample - this field presents a sample of how the dimension text will appear in accordance with specified Format and any defined Prefix and/or Suffix.
