Setting dimension value |
Scroll |
The dialog allows you to set the values of the following dimensions:
•associative sketch sizes and operation dimensions (see the section for more details. Dimensions of sketches and operations),
•derivative dimensions — dimensions of the sketch or operation, represented as detailing elements,
•associative linear, angular, diametrical and radial dimensions of a drawing or sketch, placed in parametric mode.
The set of dialog controls depends on the size for which the dialog is called. An example of a dialog called for a derived size is shown in the figure. A description of the dialog controls is given in the table.
