After specifying the fixing point, it is necessary to specify location of the leader of the dimension. Dimension<br />

parameters are specified manually in the dialog of the command's properties or with the help of the option<br />

.<br />

In addition, the following options are available in the automenu before the leader of the dimension has been<br />

tied:<br />

Dimension Parameters<br />

Set Dimension parameters<br />

Dimension parameters are defined in the command's properties window before finishing dimension creation<br />

(or editing).<br />

Dimension parameters are arranged by several sections in the properties window according to the parameter<br />

type. Depending on the type of the created dimension (angular, linear, radius, ordinate, arc length), the sets<br />

of parameters in the sections may vary.<br />

«Value» section<br />

Value. This group parameters determine, how the nominal dimension value<br />

will be defined. You can select the following choices from the drop-down list:<br />

Auto. The dimension value is calculated automatically based on drawing<br />

elements on which it is created. This allows a dimension to automatically<br />

change its value upon any modification to the drawing. The field on the<br />

right-hand side for the manual dimension value input is inaccessible.<br />

Manual. The dimension value is defined by the user manually in the input<br />

field at the right of the drop-down list. Regardless of drawing modifications,<br />

such dimension value will stay unchanged. This option is used when you<br />

need to introduce a dimension value in the drawing, that does not match the<br />

calculated dimension value.<br />

Manual with Corrections. The dimension value is specified manually by a user similar to the previous<br />

case. However, on the drawing the dimension value for the given dimension will be shown taking into<br />

consideration the specified scale and corrections (see below).<br />

By Source Lines. This option is available for <strong>2D</strong> dimensions, drawn on the elements of any associative<br />

copy. Upon selection of this option, the dimension value is determined by the original elements of the<br />

copy (if for such dimension the case “Auto” is selected, then the value of the dimension is evaluated on<br />

the basis of those elements of the copy to which the dimension is tied to).
