Description

Adds constraint parameters to entities in a dynamic block definition based on the selected constraint points or converts dimensional constraints to constraint parameters.

Method

Open the Block Editor in the Dynamic edit mode. Launch the command and select a constraint parameter type.

Select the constraint points manually or click Entity to automatically use the start and end points of the selected entity as constraint points, then place the dimension line.

The added constraint parameters are displayed in the:

  • Parameters Manager panel under Dimensional Constraint Parameters and in the Mechanical Browser, with the Block Editor open in the Dynamic edit mode.
  • Properties panel under Custom, while the dynamic block is selected.

For a selected constraint parameter, you can set the values of the Value set and the Number of grips properties in the Properties panel as follows:

  • Value set
    Limits the parameter's available values in the block reference to only those specified in the set.
    None
    Does not specify a value set.
    List
    Specifies a list of values available for the parameter.
    Increment
    Specifies a value increment and minimum and maximum values for the parameter.
  • Number of grips
    0
    No grips are displayed for the block reference. Instead, the selected geometry can be edited in the Properties panel.
    1
    A grip is displayed at just the endpoint of the parameter.
    2
    A grip is displayed at both the start point and endpoint of the parameter.

Options within the command

Entity
Uses the start and end points of the selected entity or segment as constraint points.
Linear
Creates a horizontal or vertical constraint parameter, based on dimension line and extension line origin locations.
Horizontal
Creates a horizontal (X distance) constraint parameter between two points on different entities.
Vertical
Creates a vertical (Y distance) constraint parameter between two points on different entities.
Aligned
Creates an aligned constraint parameter for the length of a line, the distance between lines, a point and a line, or between points on entities.
Entity
Constrains the length of the selected line or polyline segment.
Point & line
Constrains the distance between the selected point and the closest point on the selected line.
2Lines
Makes the selected lines parallel and constrains the distance between the two.
ANgular
Creates angular constraint parameter between two lines or polyline segments, similar to an angular dimension.
3Point
Allows you to select three valid constraint points on the entity.
Radius
Creates a radius constraint parameter on a circle, arc, or polyline arc segment.
Diameter
Creates a diameter constraint parameter on a circle, arc, or polyline arc segment.
Convert
Converts the selected dimensional constraints to constraint parameters.
