Best answer: How do you fully constrain a sketch in Catia?

How do you constrain a sketch in Catia?

Use the Sketch Tools Toolbar. Use the Constraints Toolbar.

Dimensional Constraints

  1. Keep only Dimensional Constraint activated.
  2. Click Circle in the Profiles toolbar.
  3. Select the corner center to define the one of the circle. Note that this symbol is displayed by the SmartPick as a coincidence between two points is detected.

How do you constrain lines in Catia?

Like in most of the parametric CAD software, CATIA provides two types of constraints.

Vertical/Horizontal

  1. Select the line.
  2. Click on Constraints Defined in Dialog Box. A dialog box will appear.
  3. Select Vertical or Horizontal, whichever is required.

What does it mean for a sketch to be fully constrained?

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 are not required to fully constrain sketches but it is a good practice to do so.

What is the full form of Catia?

CATIA stands for Computer Aided Three-Dimensional Interactive Application. It’s much more than a CAD (Computer Aided Design) software package. It’s a full software suite which incorporates CAD, CAE (Computer-Aided Engineering) and CAM (Computer-Aided Manufacture).

How do you draw parallel lines in Catia?

option is active (Tools toolbar).

  1. Select the geometrical elements to be constrained to each others, for example two lines to be set as parallel lines.
  2. Click the Constraint with Dialog Box icon from the Geometry Modification toolbar. …
  3. Modify the Constraint Definition dialog box. …
  4. Click OK .

Why are my lines Blue in Onshape?

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

What are the 12 geometric constraints?

We have the following geometric constraints in Inventor: Coincident constraint, Collinear constraint, Concentric constraint, Fixed Constraint, Parallel constraint, Perpendicular constraint, Horizontal constraint, Vertical constraint, Tangent constraint, Smooth constraint, Symmetric constraint, and Equal constraint.

How can you make sure a sketch is fully constrained?

When a sketch is fully constrained, the sketched features will all be the same color and will not move if they are clicked and dragged.

How do you show constraints in Catia?

Select Analyze -> Constraints . The Constraint Analysis dialog box is displayed. The Constraints tab displays the status of the constraints of the selected component: Active Component displays the name of the active component.

What is the meaning of geometrical constraint?

A geometric constraint is a non-numerical relationship between the parts of a geometric figure. Geometric constraints: Associate geometric entities together two by two (coincident, concentric, collinear, parallel, perpendicular, tangent, smooth, symmetric, equal).

What is fully constraint?

When an object is fully constrained, all relevant geometric and dimensional constraints are applied to the geometry. You should always fully constrain geometry in a dynamic block definition that contains constraints to prevent unpredictable behavior during block insertion.

Why do you need to fully dimension and constrain geometry?

Apply geometric constraints before dimensions so that the sketch shape is less likely to distort. Use both geometric constraints and dimensions. Some constraint combinations can distort under-constrained portions of the sketch.

How do you identify sketches that are not fully constrained?

If you look closely at the sketch, you will notice that it is not fully constrained. It is missing three dimensions. You can easily rectify this by constraining the center of the circles to the origin node and then adding a dimension for the larger circle.
