CAD drafting EDITING 63Command line: MCPR, PR.

The basic rules

This command is used to define the variations of the nanoCAD Mechanica design objects settings in the current drawing.nanoCAD Mechanica23 The redefinition is controlled by the parameters set in the setting of design elements.

CAD software EDITING 64

The objects are grouped by types in the dialog. The objects parameters are grouped by name.

To set the parameters or Redefinition removal filter lists are:

CAD drawing EDITING 65

If any type is selected in the parameters table , the parameters list concerning the given type is displayed.

The standard filter list allows specifying different settings for single objects created by a different design standard.

CAD drafting EDITING 66

If you select "All" standards - the changes will be applied to all objects if you select only one of the standards (eg GOST), the changes will only be used for objects belonging to the chosen standard.

Command Options

If an object type is selected, its properties will be displayed in the parameters table.

CAD software EDITING 67

Redefined parameters are shown in blue. To remove the overriding need to press the CAD drawing EDITING 68 opposite setting.

In addition, you can manually specify a new value for the selected parameter. If the new value is the same default, the blue light will not be displayed. If the selected object group only some entries have the override, the backlight will override the diagonal.

CAD drafting EDITING 69

To remove the override all objects need to click on the CAD software EDITING 70 bottom left of the dialog.

Action sequence

To change the settings of one or more design elements, you must:

      ·    Select objects

Next, in the dialog box to specify the new settings data display objects. Changes apply only to the selected objects.

Change the parameters of objects can also be by a separate command CAD drawing EDITING 71 Parameters redefinitions.

Checking the settings of design elements

To verify the design elements specify the settings, you must run the CAD drafting EDITING 72Parameters redefinition. It is proposed to select the objects that will be exposed to the command.

6. The search result will be displayed in the table.

Search result

The search result is displayed in the table. Data is sorted by mouse click in the column header. The "Next" button allows you to move the active row in the table.

CAD software EDITING 91

The table has additional commands:

      ·    CAD drawing EDITING 92Clear all - clears the search result list.

      ·    CAD drafting EDITING 93Group results by objects - displays results for objects.

      ·    CAD software EDITING 94Show object - shows the object corresponding to the selected row in the drawing. The object is shown even if it is on an inactive sheet.

      ·    CAD drawing EDITING 95Edit object - opens a dialog box for the object corresponding to the selected row.


1. Search for objects to replace.

2. In the "Replace with" input field, enter the text string to replace the found lines with.

3. Click the "Replace" or "Replace All" button:

      ·    The "Replace All" button replaces all found fragments with a new value.

      ·    The "Replace" button starts the process of successive replacement of the found fragments. To replace all found fragments, press the "Replace" button each time, while the active line will move through the table below. The "Next" button allows you to move the active row through the table, skipping the next found fragment in the list without replacing it with a new value.

Possible operators:

                  ·     = - equally;

                  ·     != - not equal;

                  ·     <, > - less - more;

                  ·     >=, <= - no less, no more;

                  ·     Like - substring search. According to this condition, all objects are selected for which the parameter value contains the substring indicated in the "Value" column.

                  ·     Unlike - substring search. According to this condition, all objects are selected for which the parameter value does NOT contain the substring indicated in the "Value" column.
