What is the definition of a fully constrained geometry in Solidworks?

What does fully constrained mean?

A sketch is fully constrained when the size and position of all sketch geometry is completely defined.

What is a constrained geometry?

Geometric Constraints. Geometric Constraints – relationships between sketch entities. This can be achieved through Dimensional or Geometric constraints. Dimensional constraints show a linear or angular distance between entities.

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.

What does it mean for a sketch to be fully constrained how does SolidWorks indicate it is fully constrained?

In order to be truly fully constrained, you have to ground at least one point on the sketch. For instance, if I have this: The sketch, though fully dimensioned, is not fully constrained – you can still drag it around on the sketch plane.

What is the color of fully constrained sketches?

The color of sketch entities indicate its constrained status: Blue means under-constrained. Black means fully constrained.

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.

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 does fully defined mean in Solidworks?

Fully defines the sketch by applying combinations of relations and dimensions. Selected entities. Applies relations and dimensions only to specific sketch entities that you select for Entities to Fully Define. Calculate. Analyzes the sketch and generates the appropriate relations and dimensions.

What is fully defined sketch?

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 do you check if a part is fully defined in Solidworks?

Method 1 – SolidWorks Design Checker:



One of the checks that this tool allows you to add is the Fully Defined Sketch Check. Simply add this to your standards file and then run this check on the active document. The Design Checker provides a list in the task pane that highlights all sketches that are under defined.

How do you fully define a Solidworks drawing?

To fully define a sketch:

1. Edit a sketch.
2. Click Fully Define Sketch. (Dimensions/Relations toolbar) or Tools > Dimensions > Fully Define Sketch.
3. Set the options for relations and dimensions in the Fully Define Sketch PropertyManager.
4. Click .

What does it mean when constraints are unsolvable in Solidworks?

Potential Reasons for These Error Messages



The sketch geometry cannot determine the position of one or more sketch entities. Unsolvable items. The sketch geometry would be geometrically invalid if the sketch were solved.

How do you constrain a sketch in Solidworks?

Search ‘Constrain All’ in the SOLIDWORKS Knowledge Base.

To fully define sketches in imported drawings:

1. Import a sketch from a . DXF or . DWG file drawing.
2. Click Tools, Dimensions, Fully Define Sketch.
3. Set options in the Fully Define Sketch PropertyManager, then click .
