Coordinate systems

There are different coordinate systems in NX. A three-axis symbol is used to identify

the

coordinate system.

1. Absolute Coordinate System

The Absolute Coordinate System is the coordinate system from which allobjects are referenced. This is a fixed coordinate system and hence the

locations and orientations of every object in NX7 modeling space are related

back to this system.

2. Work Coordinate System

The Work Coordinate System (WCS) is what you will use for constructionwhen you want to determine orientations and angles of features. The axes of the

WCS are denoted XC, YC, and ZC. (The C stands for current).

3. Move the WCS

how to translate and rotate the WCS.

Using layers

Layers are used to store objects in a file, and work like containers to collect

the objects in a structured and consistent manner.

Unlike simple visual tools like Show and Hide, Layers provide a permanent

way to organize and manage the visibility and selectability of objects in your

file.

Layer Control: There are 256 usable layers in NX7, one of which is always

the Work Layer. Any of the 256 layers can be assigned to one of four

classifications of status

Work

Selectable

Visible Only

Invisible

Reference Features

Datum Plane

Datum Planes are reference features that can be used as a base feature in

building a model.

Datum Axis

A Datum Axis is a reference feature that can be used to create datum planes,

revolved features, extruded bodies, etc.



Sketching

The sketch represents the outer boundary of that part. The

curves are created on a plane in the sketcher. The solids created

can be united into single parts using constraints. There are two

kinds of constraints

1. Geometric constraints

2. Dimensional constraints



Sketching Window



Sketching Constraints

Dimensional Constraints:

The degrees of freedom can be eliminated by giving dimensions with fixed entities like

axes, planes, the coordinate system or any existing solid geometries created in the

model. These dimensions can be linear, radial, angular etc. You can edit the dimensional

values at anytime during sketching by double-clicking on the dimension.

Geometric Constraints:

Besides the dimensional constraints, some geometric constraints can be given to

eliminate the degrees of freedom. They include parallel, perpendicular, collinear,

concentric, horizontal, vertical, equal length, etc. The software has the capability to find

the set of possible constraints for the selected entities.



Sketching Constraints Options

Show all Constraints:

Clicking this icon will show all the options pertaining to the entities in that particular sketch in

Show/Remove Constraints:

This window lists all the constraints and types of constraints pertaining to any entity selected.

Orient View to Sketch:

If the model file is rotated during the process of sketching, click on this icon to view the sketch

on a plane parallel to the screen.

Reattach Sketch:

This function allows you to reattach the sketch to the desired plane without recreating all the

curves, dimensions, and constraints.

Update Model:

When you make changes in a sketch, click on this icon to see the effects of those changes

without exiting the Sketch mode.
