What is constraints in 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.

What are dimensional constraints?

Dimensional Constraints control the distance, length, diameter, radius, and angle values of entities. Changing the value of Dimensional Constraints changes the dimension of the related entities.

What is the difference between geometric and dimensional constraints?

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 are parametric constraints in AutoCAD?

This is a new feature in AutoCAD 2010.



Parametric constraints allow you to force an object to behave the way you want it to. If you need a line to remain vertical at all times, you can set a constraint on it to do just that.

What are the different types of geometric constraints?

For example, the Fix, Horizontal, and Vertical Geometric Constraints act on a single entity, whereas Perpendicular, Parallel, Tangent, and others control two entities. You can apply Geometric Constraints to 2D entities only.
