Applies geometric and dimensional constraints for 3D entities.
Description
Applies geometric and dimensional constraints between faces, surfaces or edges of 3D entities.
The geometric constraints create a specific relationship between two subentities/entities, like parallelism, perpendicularity, tangency, coincidence, concentricity, fixed or rigid.
The dimensional constraints restrain the value of a dimension of an entity or between entities, like radius, angle or distance. It is also possible to specify the lower or/and upper bounds for the constraint value, and remove them if desired.
Select the subentities between which you will apply a dimensional or geometric constraint.

Options within the command
- New
- Allows to create a new parameter.
-
- Fix
- Applies a fixed constraint to a solid or to an edge or a face of a solid. The option is equivalent to the DMFIX3D command.
-
- Multiple
- Selects multiple entities.
- BLock
- Selects a block reference.
- Coincident
- Applies a coincident constraint between two edges, two faces, or an edge and a face of two different solids. The option is equivalent to the DMCOINCIDENT3D command.
-
- Autoconstrain
- Creates automatic constraints.
- WOrld
- Select a reference coordinate system subentity.
- PAth
- Allows a point to move along a curve by specifying the curve's parameters with an expression. The option is equivalent to the DMPATH3D command.
- CONcentric
- Applies a concentric constraint between two cylindrical, spherical or conical surfaces. The option is equivalent to the DMCONCENTRIC3D command.
- Parallel
- Applies a parallel constraint between two faces of a solid or of different solids. The option is equivalent to the DMPARALLEL3D command.
- PErpendicular
- Applies a perpendicular constraint between two faces of a solid or of different solids. The option is equivalent to the DMPERPENDICULAR3D command.
- Tangent
- Applies a tangent constraint between a face and a curved surface of different solids. The option is equivalent to the DMTANGENT3D command.
- RIgidset
- Allows to define a set of entities or subentities as a rigid body. The option is equivalent to the DMRIGIDSET3D command.
- Distance
- Applies a distance constraint between two subentities of a solid or of different solids. The option is equivalent to the DMDISTANCE3D command.
- Radius
- Applies a radius constraint to cylindrical surfaces or circular edges. The option is equivalent to the DMRADIUS3D command.
- Angle
- Applies an angle constraint between two faces of a solid or of different solids. The option is equivalent to the DMANGLE3D command.
- Edit
- Allows to edit the named constraint
-
- NodeId
- Specify the constraint by its ordered number.
- Enable
- Enables/disables the selected constraint.
- change Arguments
- Allows to change the 3D constraint arguments.
- Replace argument
- Specify the index of the argument to be replaced and its replacement.
- Exclude argument
- Specify the index of the argument to be excluded.
Note: This option is available only for RigidSet constraints.
- Add arguments
- Specify the position where the new arguments to be added.
Note: This option is available only for RigidSet constraints.
- Append arguments
- The new argument is added at the end of the list.
- Edit Arguments
- Allows to edit the list of 3D constraint arguments by selecting entities or by choosing one of the options.
Note: This option is available only for RigidSet constraints.
Edit options specific for dimensional constraints:
- Value
- Specifies a new value for the parameter
- Lower Bound
- Specifies a lower bound for the parameter.
- Upper Bound
- Specifies an upper bound for the parameter.
- eXpose
- Specifies whether the dimensional constraint is exposed when the drawing is inserted in another drawing.
-
- Geometry-driven
- Specifies whether the parameter is geometry driven.
- Properties
- Allows you to edit the arguments of the parameter.
-
- Placements
- Specifies the placement of the arguments.
-
- Direction
- Specifies the new direction of the constraint.
-
- Use as
- Specifies how to use the arguments.
- Rename
- Allows you to rename a constraint.
- Delete
- Allows you to delete a constraint.
- ?
- Lists the constraints and their status.
