What does it mean to constrain a sketch?

A sketch is fully constrained when the size and position of all sketch geometry is completely defined. This is achieved using a combination of constraints and dimensions. You don’t always need to fully constrain sketches, but it is often good practice to do so.

How do you tell if a sketch is fully constrained solidworks?

The sketch is fully defined if the lines on the sketch are all black. This means that there can be no unexpected changes within the model due to all the geometry of the sketch being fully defined.

How do you fix a over defined sketch in Solidworks?

To manually repair over defined sketches:

In the PropertyManager, under Message, click Manual Repair. All relations and dimensions in the sketch appear under Conflicting Relations/Dimensions.
Select each relation or dimension to highlight it in the graphics area. For example: …
Click Delete. Valid solution found. …
Click .

What does fully constrained mean?

If geometry is controlled such that you cannot change it without redefining the relationships—changing constraints, dimensions, or parameters—the geometry is fully constrained.

How do you hide a sketch relationship in Solidworks?

Click Tools > Sketch Settings, and toggle Automatic Relations. How do I toggle the display of sketch relations? (View toolbar) or View > Hide/Show > Sketch Relations to toggle the display of sketch relations.

What is a fully defined sketch in Solidworks?

The Fully Define Sketch tool calculates which dimensions and relations are required to fully define under defined sketches or selected sketch entities. You can access Fully Define Sketch at any point and with any combination of dimensions and relations already added.

How can you correct an over defined sketch?

There are two common ways to fix over defining dimensions.

Delete the over defining dimension in the graphics area.
Right-click the over defining dimension in the graphics area and select Properties. …
When you add a dimension that over defines a sketch, the Make Dimension Driven dialog box appears.

What are some examples of sketch constraints?

You can also hide and show the constraints using the sketch palette.

Coincident Constraint. …
Collinear Constraint. …
Concentric Constraint. …

How do you constrain to Origin?

Select the browser node Center Point to include the origin point as a point in your sketch. Click Sketch tab Constrain panel Coincident Constraint. Select the lower endpoint of the left-most line, and then the projected origin point.

What evidence can you present to support your claim that the sketch is fully constrained?

An arc has four degrees of freedom: center, radius, and end points. If you eliminate all degrees of freedom by applying constraints or dimensions, the sketch is fully constrained. If any degrees of freedom remain unsolved, the sketch is under-constrained.

Why is my sketch under defined solidworks?

In this tech tip we’ll answer the common question: Why is my SOLIDWORKS Sketch Pattern Under Defined? The reason is because the sketch instances can rotate. You could previously Fully Define the instances by adding a Horizontal or Vertical relation on one of the construction lines tied to the instances.
