Parametric (dimensional constraints)

GstarCAD 2027 · Whats New

Parametric (Dimensional Constraints) is a powerful tool for controlling the size and position relationships of graphics objects, ensuring that the size and shape of graphics remain consistent during editing.

Including: 1) 7 kinds of dimensional constraints, respectively: linear, horizontal, vertical, aligned, angular, radius, diameter; 2) 2 clock auxiliary functions: form, convert.

This feature is only available in Premium version.

Add the following parametric constraint-related commands:

1、DIMCONSTRAINT

Controls the size and position relationships of graphics objects, ensuring that the size and shape of graphics remain consistent during editing.

2、DCLINEAR

Constrains the horizontal or vertical distance between two points.

3、DCHORIZONTAL

Constrains the X distance between points on an object, or between two points on different objects.

4、DCVERTICAL

Constrains the Y distance between points on an object, or between two points on different objects.

5、DCALIGNED

Constrains the distance between two points on an object or between two points on different objects.

6、DCANGULAR

Constrains the angle between line or polyline segments, the angle swept out by an arc or a polyline arc segment, or the angle between three points on objects.

7、DCRADIUS

Constrains the radius of a circle or an arc.

8、DCDIAMETER

Constrains the diameter of a circle or an arc.

9、DCFORM

Specifies whether the dimensional constraint being created is dynamic or annotational.

10、DCCONVERT

Converts associative dimensions to dimensional constraints.

11、DCDISPLAY

Displays or hides the dynamic constraints associated with a selection set of objects.

12、CONSTRAINTSETTINGS

Controls the display of geometric constraints within the CAD software.

13、PARAMETERS

Controls the associative parameters used in the drawing.

Added parametric constraint related system variables:

1、 CCONSTRAINTFORM

Controls which to be applied to objects, the annotative constraint or dynamic constraint.

2、CONSTRAINTNAMEFORMAT

Controls the text format of labeled constraints in the CAD software.

3、DIMCONSTRAINTICON

Controls the display of the lock icon for dimensional constraints.

4、DYNCONSTRAINTMODE

Displays hide dimension constraint when selected constrained objects.

5、PARAMETERCOPYMODE

Controls how to deal with constrains and users parameters of reference when copying constrained objects between drawing, model space, and layouts, and block definitions.

6、PARAMETERSSTATUS

Specifies whether the parameter manager is displayed or hidden.
