## How do you use Symmetry constraints?

Video quote: *Let's go ahead and select that point there right so notice that you can either have the symmetry clip. Or a pose which is what we want. Once we hit okay. If. I move the right plane.*

## What is use of coincident constraint?

The Coincident constraint **causes two points to be constrained together, or causes one point to lie on a curve**. In a 3D sketch, a coincident constraint can also cause points and lines to be constrained to surfaces.

## What are the four types of constraints in Inventor?

There are 4 tabs: **Assembly, Motion, Transitional, and Constraint Set**. The one we will use first is the Assembly. There are 5 different types of constrains in the Assembly tab: Mate, Angle, Tangent, Insert, and Symmetry.

## How do constraints work in Inventor?

Autodesk Inventor uses constraints in two primary ways: **2D and 3D sketch constraints control geometry within sketches**. **Assembly constraints and joints establish relationships between components in an assembly that control position and behavior**.

## How do you use symmetry in Fusion 360?

**Add a symmetrical constraint to a sketch**

- Click Sketch > Constraints > Symmetry . The Symmetry constraint icon displays next to the cursor in the canvas.
- In the canvas, select the sketch geometry you want to constrain.
- Select the line of symmetry.

## What is a concentric constraint?

The concentric constraint **causes two arcs, circles, or ellipses to have the same center point**.

## How do you use a concentric constraint?

Video quote: *Here's an example of a common real-world use for the concentric constraint a section of tubing has inner and outer diameters. For consistent wall thickness. Both diameters must share the same center.*

## How do you create a concentric constraint in Inventor?

Video quote: *So by selecting first one circular object and then another circular object.*

## How do you constrain an arc in Inventor?

Video quote: *Line going up to the constraint menu of the ribbon choose the concentric option in order left click on the top circle followed by the inner top circle. And then the bottom two circles.*

## How do you constrain parts in Inventor?

**To use Constrain to place Mate or Flush constraints**

- On the ribbon, click Assemble tab Relationships panel Constrain .
- On the Assembly tab, the Type is set to Mate by default. …
- Select the Predict Offset and Orientation check box if the components are close to the desired position.

## How do you constrain a point to the origin in Inventor?

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 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.

## What are geometric constraints in Inventor?

**A constraint that causes lines or axis of curves to meet at right angles**. This constraint is often inferred while sketching. Parallel. Causes 2 or more lines or ellipse axes to be equal distance from each other.

## Where are geometric constraints in Inventor?

**In the graphics window**, click to set the point to constrain. Click the geometry to which the point is constrained. Right-click and choose Done, press Esc, or select another tool or command.

## What are the different types of geometric constraints that are applied to sketches and what are their functions?

Some examples of geometric constraints include **parallelism, perpendicularity, concentricity and symmetry**. Parallelism occurs when two or more lines or axes of curves are equidistant from each other. Perpendicularity is a constraint in which lines or axes of curves intersect at right angles.

## What are geometric constraints and why do we need them?

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. With constraints you can: include formulas and equations within dimensional constraints.

## What is a geometric constraint of Fusion 360?

Video quote: *And then click on the lines. And now they're parallel and they'll remain so until I delete their constraints which I can do by just selecting and hitting delete if I have two circles.*

## How do we distinguish between derived dimensions and regular dimensions on the screen?

How do we distinguish between derived dimensions and regular dimensions on the screen? **Derived has parenthesis, regular doesn’t**.

## How do we display and examine the existing constraints that are applied to the sketched entities?

How do we display and examine the existing constraints that are applied to the sketched entities? **Right click -> show all constraints**.

## When extruding What is the difference between distance and through all?

When extruding, what is the difference between Distance and Through All? **The through all will go through the object completely, and the distance command will allow you to enter a distance**. You just studied 6 terms!

## What is the basic concept of the born technique?

The BORN technique or (Base Orphan Reference Node) is the basic concept of **creating your features around your Origin References**; Namely your XY, YZ, XZ planes, XYZ axes, and Center Point (0, 0, 0) of your model.

## What is the first thing we should set up in Autodesk Inventor when creating a new model?

What is the first thing we should set up in Autodesk inventor when creating a new model? **Create a sketch that is proportional to the desired shape**. Exaggerate the geometric features of the desired shape.

## How can we confirm that a sketch is fully constrained?

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.

## Which type of dimension is displayed with parentheses?

**Driven dimension**. Enclosed in parentheses as displayed in the graphics window, and allows route geometry to respond dynamically to associated changes.

## Which line is thin dark and has arrowheads on each end?

The dimension line

**The dimension line** is a fine, dark, solid line with arrowheads on each end. It indicates direction and extent of a dimension. In machine sketches and drawings, in which fractions and decimals are used for dimensions, the dimension line is usually broken near the middle to provide open space for the dimension numerals.

## What does ref on a drawing mean?

REFERENCE

REF on drawings is generally defined as **REFERENCE**. These dimensions are to be used as reference only.
