Once you enable Inferred Constraints, AutoCAD will automatically add geometric constraints as you create or modify objects in your drawing. Use the Rectangle tool in the ribbon to create a new rectangle. With Infer Constraints toggled on, AutoCAD automatically adds the appropriate constraints to the rectangle.

What are inferred constraints?
Infer Constraints scans the layout to determine the most effective set of constraints for all views. It makes a best effort to constrain the views to their current positions while allowing flexibility.
What is the use of constraints in AutoCAD?
Constraints are rules that are applied to 2D geometry. By applying constraints, you can control the location, size, distance, angle, and other parameters of objects in a drawing. As a result, you can identify and maintain specifications in a project.
What is the purpose of geometrical constraints?
A geometric constraint imposes relationships between geometric entities such as tangency, collinearity, parallelism, perpendicularity, coincidence of points, symmetry, etc. Dimensional constraints may be used to indicate the size of specific entities or the relative location between different entities.
What are drawing constraints?
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.
What is inferred in NX?
In NX, if the inferred constraint is on, if you draw a circle, it gives you the alignment indicator in the middle of the circle as you draw a second one. It automatically adds that new alignment constraint, so if you move one circle, the other moves with it, keeping them aligned.
How do I turn off constraints in AutoCAD?
- On the command line in AutoCAD, enter CONSTRAINTINFER and set the value to 0 (zero)
- Enter CONSTRAINTSETTINGS command and on the Geometric tab, uncheck the box for “Infer geometric constraints.”
What is the difference between dimensional constraints and geometric constraints?
There are two types of constraints: geometric and dimensional. Geometric constraints are used to control the relationships of objects in respect to each other. Dimensional constraints are used to control the distance, angle, radius, and length values of objects.
What is the difference between numeric and geometric constraint?
Simply put, a geometric constraint relates to other parts of a geometric figure, whereas a numeric constraint is a set number not relative to other parts of a design. Both geometric and numeric constraints define the dimensions of objects in computer-aided design, or CAD, modeling systems.
What does a coincident constraint do?
The Coincident constraint causes two points to be constrained together, or causes one point to lie on a curve. In a 3D sketch, a coincident constraint can also cause points and lines to be constrained to surfaces.
What is a tangent constraint?
Tangent constraints constrain an object’s orientation so that as an object moves along a curve, the object always points in the direction a curve. The curve provides the path of the object’s motion, and the object orients itself to point along the curve.
What is parametric drawing?
Parametric drawing is a technology that is used for designing with constraints, which are associations and restrictions applied to 2D geometry. There are two general types of constraints: Geometric constraints control the relationships of objects with respect to each other.
How do we distinguish between derived dimensions and driven dimensions on the screen?
How do we distinguish between derived dimensions and regular dimensions on the screen? Derived has parenthesis, regular doesn’t.
What role do constraints play in sketches?
Sketch constraints are a fantastic way to ensure accuracy in your sketching. Through constraints you can ensure something is on the midpoint, is perfectly concentric, won’t move from a line and more. Constraints are perfect for designing functional pieces for 3D printing.
Why is it important to fully constrain a sketch?
However, when it is approaching complete, you will want to fully constrain the sketch. It is because you don’t know if the sketch has been changed inadvertently or mistakenly violating the design intent. The point to create a sketch is to define a rigid shape (solid or surface).
What three types of constraints can be applied to CAD sketches or models?
The three types of constraints that can be applied to CAD sketches or models are geometric constraints, numerical constraints, symmetrical constraints.
