All siemens NX

The options under All (Legacy) let you modify existing non-associative curves using the pre-NX7.5 dialog boxes.


All (Legacy) is only available by adding it to a toolbar or a menu using Customize→Commands.

You can edit a number of curve types using a Selection Steps dialog similar to the one that was used to create them. The creation and editing of these types of curves is covered in the same section of the documentation (for example, see Offset Curve and Wrap/Unwrap Curve).

The All (Legacy) option opens a dialog with all non-associative edit curve functions.

Edit Curve (All) Dialog Options For Non-Associative Curves


Point Method

Used to change the position of a line endpoint. The Point Method options let you specify points relative to existing geometry, or by specifying a cursor location or using the Point Constructor. In some cases, you will use the Snap Point tool instead of the Point Method options.

Edit Arc/Circle By

You can edit an arc or circle two ways: by editing its Parameters, or by Dragging it.

Complement Arc

Lets you create the complement of an existing arc.

Display Original Spline

If you are editing a spline, this option lets you display the original spline for comparison during the editing.

Edit Associative Curve

By Parameter lets you edit an associative curve while preserving its associativity.

As Original breaks the associativity between the curve and its original defining data (you receive a warning).

Arc Length Trim Method

Total – Use this method to extend or trim a curve by its total arc length. Total arc length is the distance from the start of a curve to the end of the curve, following the exact path of the curve.

Incremental – Use this method to extend or trim a curve by a given arc length increment. The arc length increment is the length used to extend or trim from the original curve.

This option is also found under Edit Curve Length.

Arc Length

Lets you enter a value for the length of the extended or trimmed arc.


Use this option to update your model after making edits to curves, without exiting the Edit Curve dialog.

Click on the following topics for additional information for editing non-associative curves:

Editing a Line

Editing an Arc or Circle

Editing an Ellipse

Editing a Spline

Use Edit→ Transform to change the location of an associative or non-associative curve. However, some functions, such as copy, remove the relationship between a dependent curve and its associated geometry. In many cases, you are warned if a transformation would have this effect. For cases like a copy operation or circular/rectangular instance arrays, no warnings are issued.

Editing Associative Curves

To edit associative (feature) curves, select the curve in one of the following places:

  • The graphics window, followed by MB3→ Edit Parameters

  • The Part Navigator, followed by MB3→ Edit Parameters

  • The Edit→ Feature dialog listing

For more information on associative curves, see Edit Curve Parameters.
