The goodies for working with 2D constraints in the Inventor Sketch Environment are located on the Sketch tab > Constrain panel. For example, an horizontal line, a circle centered at the endpoint of a line geometry, a line that is perpendicular to another line, or a circle that is tangent to another circle. Geometric constraints defines the geometric relationship between geometry in the sketch. You can also apply a dimension that makes the angle between two lines to be 60 degrees. Nothing can make that line become 200.0001 mm unless the parametric dimension is edited. For example dimensional constraints (or simply dimensions) can set a line to be 200mm. The dimensions drive or determine the sizes and orientations of geometry in the sketch. There are two types of 2D constraints in Autodesk Inventor, namely:ĭimensional constraints are simply parametric dimension. By the time you begin sketching with 2D constraints in Autodesk Inventor, you will be amazed by their sheer power! So let's continue. USING 2D CONSTRAINTS IN THE SKETCH ENVIRONMENTīefore we continue, Let me say, for the records, that 2D constraints can perform what Object Snaps, Object Snap Tracking, and Polar Tracking does in AutoCAD and even more. Differentiate between drawing in AutoCAD and sketching in Inventor.Explain the concept of constraints in Autodesk Inventor.OBJECTIVESĪt the end of this lesson, the reader should be able to: They are used to define the relationship between parts, or components in an assembly. They are used to define the sizes of geometry and the relationship between them in the Sketch Environment - which is Autodesk Inventor 2D environment.ģD constraints are only available in the Assembly Environment.

In Autodesk Inventor, we have two types of constraints, namely:ĢD constraints are only available in the Sketch Environment. But I can tell you, you may use them easily unless you have worked with a parametric design application like Inventor. So, you can redefine constraints in AutoCAD just like you can do in Inventor.

It is worth noting that parametric design was introduced into AutoCAD from AutoCAD 2010. These constraints that help define these sizes and relationships are known as parameters. The only to rearrange or edit the sketch, model, or assembly is to edit or redefine the constraints that were applied to the sketch geometry or part (or components). This way, the sketch, model, or assembly is stable, and cannot be easily rearrange or scattered deliberately or inadvertently. In the assembly environment, you use Inventor 3D constraints to define strict relationships between parts, or components in the assembly. That is why it is called "a sketch." You simply sketch approximate sizes and orientations of your geometry and then use Inventor 2D Constraints to define strict sizes and relationship between the sketch geometry. In Inventor sketch environment, you do not need to bother yourself by creating precise geometry from the start. However, in Autodesk Inventor, the story changes. AutoCAD does not associate or define any strict relationship between those parts as they are being assembled. In AutoCAD 3D, you use 3D modifying tools like 3D Move, 3D Rotate, and 3D Align to assembly various parts to form an assembly. You cannot use the dimension to control the length of the line. So you must always create precise geometry from the word "go." When dimensions (AutoCAD) are placed in the drawing, the dimensions merely report the size of the line. So if you want a horizontal line of say 200mm, you have to use polar tracking to set the direction of the line to either 0 or 180 degrees, and then type the precise length of 200. In AutoCAD, the familiar and common workflow is to create precise geometry by using the commands on the Draw panel or toolbar.

It is called a parametric modelling software because the sizes of the geometry and the relationship of between the geometry in your sketches, the height or extent of your extrude feature, the relationship between parts in an assembly, etc, are all controlled and driven by parameters. The first thing you have know about Inventor is that it is a 3D parametric design software. Well, in the lesson, I'll try to answer these questions.
