4.3.1 Creating points

In this exercise you'll learn about the feature Point, which is used to create points in 3D space.

---

Complete the following steps to create datum points:

Insert -> Datum/Point -> Point or .

The window Point pops up. (refer figure "Point")

Here you can create (parametric) points in space. NX offers options for positioning points when  is selected. You can limit these options by using Snap Points:

Button	Name	Description
	Endpoint	selects endpoints
	Midpoint	selects midpoints
	Control Point	selects mid- and endpoints of curves and nodes of splines
	Intersection	selects intersections
	Arc Center	selects the center of circles or arcs
	Quadrant Point	selects quadrant points (refer icon representation)
	Existing Point	selects existing points, like the point of origin or previously defined points
	Point On Curve	general selection of any point on a curve

By choosing or you can select two points and NX generates a point in the middle.

With Location between Points -> % Location you can enter a relative position for the point between two other points. The percentage descibes the location between both points, with 0% meaning Point 1 and 100% Point 2. (refer figure "% Location")

 

Hint:

If you enter definite coordinates for Coordinates, the point will not be created parametrically. In this case a later change to the dimensions of the body will not affect the position of the point.

To close this mode, click OK.

Showing and hiding datum points

To select points:	Select the specifc points by directly clicking or using the Part Navigator.
To hide points:	Edit -> Show and Hide -> Hide.

Hint:

Note possible differences between the absolute coordinate system and the WCS.
