Wrangling the WCS

Having a working coordinate system (WCS) that can easily be moved around makes life easier for the designer. Choosing a convenient coordinate system and entering values directly is much simpler than transforming all the desired coordinates into the absolute coordinate system (ACS). The benefits of having a WCS are not only for the designers using interactive NX, programmers can also use the WCS to make their lives easier too.

Break dimension extension lines

It is good practice to place drawing dimensions so that the extension lines do not intersect other dimension lines. However, occasionally such placement is unavoidable. While I do not believe it is required by any major drafting standard, some people prefer the aesthetic of adding a break, or gap, to one of the lines at the point of intersection. NX provides a custom symbol, the gap symbol, to provide for the appearance of a gap in the desired extension line.

Change Expression Units

The expression system in NX is "'unit aware" and can correctly handle a wide variety of unit types. This can make life easier since the designer no longer has to worry about unit conversions when creating expressions. Create a new length expression using units of centimeters, add an existing expression defined in inches to another defined in millimeters and you get the correct length expressed in centimeters.

Change ID Symbol Type

When creating an ID symbol in NX, the dialog box provides a drop down menu with a variety of choices for the shape of the symbol. You pick one that should work and go about finishing the drawing. Unfortunately, the checker returns your drawing with a note explaining that you picked the wrong symbol shape for that particular usage. "No problem", you think. "I'll simply edit the symbol and change the type." You double click the symbol, the edit dialog box appears but the symbol type option is missing.

Blend Reference Cleaner

remove missing parents from edge blend features

I don't think this will come as news to anyone, but edge blend features depend on edges in the model. This sounds really obvious (which it is), but given how even minor edits can create or remove dozens of edges, it is surprising how stable the edge blend features really are. When a parent edge is modeled away, the edge blend feature will 'remember' where it used to be and display a warning icon in the feature tree. Occasionally, these warnings are very useful to track down unintentional changes; but more often than not, you are well aware of the changes and simply want to remove the old blend parents and get rid of the warning.
