Autodesk inventor 2018 constraints free. To Apply Geometric Constraints



  Fortunately, Inventor will automatically tell you the number of constraints required to set all the necessary dimensions in your design. Using. Autodesk Inventor uses constraints in two primary ways: 2D and 3D sketch constraints control geometry within sketches Assembly constraints. Use the Constrain command or Assemble command to place an Insert constraint. An Insert constraint places a planar and axial mate as a single.    

 

5 Common Problems for New Inventor Users - Applied Software



   

As you sketch, apply geometric or dimensional constraints to reduce this number to zero and fully constrain, or stabilize, your sketch geometry. Geometric constraints are created automatically between lines, arcs, and other geometry as you sketch. Constraints can also be manually applied after the sketch geometry exists to stabilize sketch shape or position.

These geometric constraints allow the sketch to be edited with predictable results. Constraints are inferred when sketching new or modifying existing geometry.

This process of inference decides which constraints are available to the geometry as the shape and orientation are varied. As a constraint is inferred, the constraint symbol is shown, as well as dotted alignment lines, if applicable.

Constraint persistence determines if inferred constraints are maintained after the geometry is created. If constraint persistence is turned off, constraints are not created automatically. Varying inference and persistence settings can affect the results of sketch operations.

Parametric dimensions , a type of sketch constraint, control the size and position of geometry. Dimensions are created automatically when you enter values in the input boxes as you create geometry or manually using the General Dimension command. Dimension values can be expressed as numeric constants, as variables in an equation, or in parameter files. Edit a dimension to change the size of the associated geometry. You can edit sketch dimensions before or after a sketch becomes part of a feature.

If a sketch has not been consumed by a feature, its dimensions are visible and can be edited. After a sketch is consumed by a feature, select the feature in the browser and activate the sketch for editing.

If applying a dimension would over-constrain the sketch, you can accept or cancel the dimension. If you accept the dimension, the dimension is saved as a reference parameter, its value is enclosed in parentheses, and it updates in response to changes in normal dimensions. You can also choose how dimensions are displayed using options in the status bar at the bottom graphics window. Pin Apply to cylindrical faces.

Prevents the faces from moving or deforming in combinations of radial, axial, or tangential directions Frictionless Apply to a flat or cylindrical surface. Prevents the surface from moving or deforming in the normal direction relative to the surface. In the dialog box, with Location active, select the constraint location.. The available constraint types are: Access Constraint Type Used to Note: You can also right-click the Constraints node in the browser and select the appropriate constraint type from the context menu.

To apply a custom constraint Custom constraint enables you to customize all parameters of the constraint position, orientation, degrees of freedom for rotation and displacement on beam or node.

Parent topic: Prepare for analysis. Apply pinned constraint when no displacement and free rotation is allowed on beam or node. Apply floating pinned constraint when free rotation and free displacement in one plane is allowed on beam or node. Apply custom constraint to specify your own degrees of freedom of displacement and rotation on beam or node.

On the ribbon, click Frame Analysis tab Constraints panel Custom. Select beam or node to position the constraint.
