DMCONSTRAINT3D command

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.

Select the subentities between which you will apply a dimensional or geometric constraint.

Press the TAB key to select obscured geometry.

Options

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.
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.
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
Enable
Toggles the selected constraint Enable/Disable.
Value
Type a value in the Command line.
type a value in the Command line.
Choose whether the parameter is visible and can be modified when the component is inserted in an assembly:
Auto
The parameter is exposed only if it does not depend on other parameters.
ON
The parameter is always exposed.
OFF
The parameter is never exposed.
Geometry-driven
For parametric constraints, choose whether the constraint is ordinary or geometry-driven.
Rename
Allows to rename a constraint.
Delete
Allows to delete a constraint.
