You asked: What is the difference between dimensional constraints and geometric constraints in Solidworks?

What are dimensional and geometric constraints?

Dimensional constraints show a linear or angular distance between entities. Geometric constraints are more fundamental than this and describe the characteristics of the relative position of entities.

What are geometric constraints in Solidworks?

Geometric Constraints define relationships that force dependencies and limitations between entities. There are two types of Geometric Constraints: those that act on a single geometric entity and those that define a relationship between two geometric entities.

What are dimensional constraints in Solidworks?

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 geometric constraint?

Geometric constraints define specific points on geometric objects and determine their orientations to other objects. Some examples of geometric constraints include parallelism, perpendicularity, concentricity and symmetry. Parallelism occurs when two or more lines or axes of curves are equidistant from each other.

How do we distinguish between derived dimensions and regular dimensions on the screen?

How do we distinguish between derived dimensions and regular dimensions on the screen? Derived has parenthesis, regular doesn’t.

How do you use geometric constraints in Solidworks?

To apply Geometric Constraints:

  1. Type GeometricConstraint.
  2. Specify an option: …
  3. The options correspond to the choices provided by individual Geometric Constraints commands.
  4. Follow the command prompts.
  5. The subsequent sequences of the GeometricConstraint command are identical to those of the individual command variants.

How do you make a dimension dependent on another dimension?

Double click the dimension, then in the Modify dialog box, type = (equal sign) and several characters of the global variable name. A flyout menu appears with a name that matches the characters you have typed. Both dimensions become linked to the global variable. Repeat for as many dimensions as needed.

What is a geometric constraint in Inventor?

A constraint that causes lines or axis of curves to meet at right angles. This constraint is often inferred while sketching. Parallel. Causes 2 or more lines or ellipse axes to be equal distance from each other.

What are parametric constraints?

Parametric constraints ensure that a drawing maintains its original precision by maintaining the relationships between an object and world space, between two objects, or within the object itself. There are two types of parametric constraints: dimensional and geometric.
