Quick Answer: What is the Colour of over constrained elements in Catia Sketcher?

What is the color of over-constrained sketches?

Over-constrained sketch is one in which duplicate dimensions or conflicting geometric constraints or both are present. Over-constrained sketch becomes MAGENTA in color.

How do you constrain sketches 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.

What is ISO constrained in Catia?

If all of the degrees of freedom of a geometry have been taken up by a consistent combination of dimensions and fixed geometry, that geometry is said to be iso-constrained (also known as well-defined). Geometry that still has some degrees of freedom is said to be under-constrained (also known as under-defined).

What is under constraints in Catia?

To create a precise 2D sketch in CATIA, we use constraints. What does “constraint” actually means? It means that we are restricting the degree of freedom of the sketch. Consider, you want to constraint a line. If you provide its length, then it ensures that the length of the line is under control.

What does over constrain the sketch mean?

Causes: The degrees of freedom affected by the current action are fully defined in the sketch with constraints and/or dimensions. By adding another dimension or constraint, violates or contradicts existing constraints or dimensions. This produces the overconstrained condition in the sketch.

What is meant by over constrained?

Also in engineering and mathematics, overconstrained is used when there are too many simultaneous equations to result in an exact solution. For example, fitting a line to many points is overconstrained because technically a line cannot be drawn simultaneously through all of the points.

How do you constrain parts in Catia Assembly?

Select the Constraints of Given Components: Select the components, right-click and select xxx object -> Component Constraints contextual command. Editing Constraints: you can cut and paste , copy and paste and even delete constraints. Update an Assembly: constraints displayed in black indicate they need an update.

How do you constrain a rectangle in Catia?

This one is pretty easy: Dig into the Rectangle flyout, and the Centered Rectangle will be hiding one spot from the right. Click the command, choose a center point, then click one more time to get the size the rectangle. The rectangle is automatically constrained around the center point.

How do you constrain 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 .

What is under constrained?

If you do something under constraint, you do it only because you have been forced to: They confessed, but only under severe constraint.

Who invented CATIA?

CATIA started as an in-house development in 1977 by French aircraft manufacturer Avions Marcel Dassault to provide 3D surface modeling and NC functions for the CADAM software they used at that time to develop the Mirage fighter jet.

How many workbenches are there in CATIA?

CATIA contains 92 different workbenches. This is a list of brief descriptions explaining what each workbench is designed to do.
