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.
