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

What does it mean when a sketch is 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 don’t always need to fully constrain sketches, but it is often good practice to do so.

How do you constrain sketches?

Tips for Working with Sketch Constraints

  1. Stabilize shape before size. Apply geometric constraints before dimensions so that the sketch shape is less likely to distort.
  2. Use both geometric constraints and dimensions. …
  3. When possible, use auto-dimension. …
  4. Place dimensions on large elements before small ones.

How do I auto constrain in CATIA?

The Auto Constraint dialog box is displayed. The Elements to be constrained field indicates all the elements detected by the application after selecting the profile. Click the Symmetry lines field and select the vertical line in the geometry area.

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

Select part selection (How to select parts, edges, faces and sketches in an Inventor assembly). Select part and drag/move the part. If parts will do not move this means that is fully constrained.

How do you constrain a sketch to the origin?

On the ribbon, click Sketch tab Draw panel Project Geometry. 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 is the color of fully constrained sketches?

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

How can you remove a constraint?

To delete a check constraint

  1. In Object Explorer, expand the table with the check constraint.
  2. Expand Constraints.
  3. Right-click the constraint and click Delete.
  4. In the Delete Object dialog box, click OK.

How do you constrain a 2D sketch in Inventor?

On the ribbon, click Sketch tab Constrain panel Fix (2D) or click 3D Sketch tab Constrain panel Fix (3D sketch). In the graphics window, click a curve, center point, midpoint, or point. Click curves or points to fix, as desired. Right-click and choose Done, press Esc, or select another tool or command.
