Optimizing NX display settings for use with Fibersim

As Fibersim relies on linking to CAD curves, then displaying boundaries overlayed upon them, the quality of the display is critical to a clear understanding of what is being highlighted.  In NX, this “display geometry” uses the user-defined part and session settings for curve display.  Changes in NX 10 drafting resulted in some default line settings that have a negative impact on the visibility of Fibersim’s display geometry.  Following are a few simple tips for ensuring that your NX settings are optimized for displaying Fibersim geometry:

  1. Show Widths
    • Make sure you have the “Show Widths” option turned on. This can be found under File > Preferences > Visualization > Line.
  2. Reset Pixel Widths
    • Once the Show Widths option is turned on, the “Pixel Widths” will be used to assign a set number of pixels to each of the 9 widths. Fibersim is set up to display geometry using the 1st, 3rd, and 4th widths, and assumes that they are each set to 1, 3 and 4 respectively as that was the default when the 9-width format was introduced in NX 9.
    • With NX 10, the default value of the first 4 widths was assigned as 1 pixel, meaning that all Fibersim geometry will display as “thin” lines. To optimize this, assign each width an ascending thickness from 1-9 as follows:NXDisplaySettingsPixelWidths.jpg
    • As these settings are stored with the part, each part must be reconfigured separately.
    • Tip: If you configure your Customer Defaults (File > Utilities > Customer Defaults > Gateway > Visualization > Line) with these width values, you can simply press “Reset to Defaults” and NX will copy in your default values into the work part.
  3. Make CAD curves thin
    • Depending on your default object settings, step 2 may make all your existing curves and edges very thick (the default NX 10 setting is .70mm, which will go from 2 to 6 pixels!)
    • To change existing curves and edges, simply select all (CTRL+A) without any selection filter, Edit Display settings (CTRL+J) and set the object Width to the thinnest setting:

    • To make the change for all future curves and edges, change the Object Preferences (File > Preferences > Object ) setting for Width to the thinnest setting
    • Tip: to ensure future parts respect the same thin width settings, you can make the same change to your Customer Defaults (File > Utilities > Customer Defaults > Gateway > Object > Default > Width)
  4. Disable Wireframe Contrast
      • The final optimization affects the color of the Fibersim display geometry. Most Fibersim display geometry is colored green, blue, red or yellow, depending on the orientation of plies.  NX has a visualization setting designed to improve the contrast of wireframe geometry when viewed against a light background that alters these colors and makes them all a bit darker and drabber.
      • To disable this setting and restore the true colors, go back to the line visualization settings (File > Utilities > Customer Defaults > Gateway > Visualization > Line) and uncheck “Wireframe Contrast”
      • Since this is a session setting, it only needs to be changed once, after which all parts will be displayed in the same manner.
