Ahh, the first signs of spring in the United States! Sunshine, blue skies, and the promise that summer is just around the corner. Everything seems new–except that old pile of junk sitting in the attic!
Spring cleaning is a tradition that has been around for ages. In the 1800s, lamps inside the home were lit with whale oil or kerosene. They needed to be heated with wood or coal, which in turn left a huge mess. Windows had to be opened to let the soot out, and this could only be done during warm weather.
It’s time to change with the seasons and do some spring cleaning! Don’t forget about NX during this busy time of year, though! While there may be many parts in your home to clean this spring, there are parts to clean up in your favorite CAD software as well.
Part cleanup does a number of things. These benefits help you work more efficiently and make parts better moving forward. Remember, if you don’t need it, get rid of it! Just like that pile of junk in the attic. Take a look at what you can do with Part Cleanup below.
Specifies the kind of objects to clean up. Select from the following options:
A partially loaded part may not contain the data that needs cleaning. In this case,NX does not modify the partially loaded part until it is fully loaded.
Simple Cleanup Actions
Remove Extraneous Highlighting
Removes the highlighting on objects that are no longer in a selected state. This is the only Part Cleanup option that works on the displayed part instead of the work part.
Moderate Cleanup Actions
Performs solids cleanup. NX analyzes all solid bodies in the work part and attempts repair.
Clean Mating Objects
Performs cleanup of mating conditions. Corrupt objects are removed from the part file. This option loads components when necessary.
Clean Assembly Constraint Objects
Performs cleanup of assembly constraints. Constraints that are corrupted are removed from the part file. This option loads components when necessary.
This cleanup is useful when you have problems with assembly constraints when loading an assembly.
See the Assemblies Help for more information.
Clean Manufacturing Objects
Deletes or fixes any corrupt internal objects. For example, if internal parameter sets are corrupt, they would be unusable, and you would need to use this option to delete them. Clean Manufacturing Objects may reduce the size of your part file considerably.
Clean Drafting Objects
Fix Off-plane Sketch Curves
Repairs certain curves that are off the sketch plane.
When you copy and paste a sketch across planes that are far apart (typically 1000mm or more), or when you import I-DEAS parts that contain sketches, NX may create lines and/or arcs that are off the sketch plane by extremely small distances. Off-plane sketch curves can cause certain types of update errors. For example, an Extrude operation might fail because of overlapping or disjointed curves.
Fix Off-plane Sketch Curves examines all sketches in the current part. If a line or arc is less than 1e-04mm from the sketch plane, NX moves the curve back onto the plane. Curves that are more than 1e-04mm from the sketch plane remain unchanged.
Clean Interpart Links
Removes the associativity of smart objects that reference broken interpart links. Such links can break when the component is deleted, or if the object in the component part is deleted. This does not delete WAVE features as these can be deleted or reassociated interactively. This is mainly used for cleaning up links created by the Routing module.
Clean Routing Objects
Removes unnecessary routing data.
Repairs routing objects and routing specific constraints.
Moderate Delete Actions
Delete Unused Objects
Deletes all extraneous objects from the work part. Extraneous objects are objects no longer accessible, and are not needed by any user-accessible objects. (Normally, extraneous objects are automatically deleted by the system, but in some situations this does not happen.)
Delete Unused Fonts
Removes character fonts that are not used in any drafting text in the current part. These fonts are typically left over from a part converted from Unigraphics V13.0, or if you select a font in File tab→Preferences group→Preferences→Visualization→Visual and then do not use it.
Specifies whether empty groups should be deleted during the cleanup. Select from the following groups:
Serious Delete Actions (Use Caution)
Delete Unused Expressions
Removes expressions that are not used in the current part. All expressions with no references in the part are deleted, including any expressions that are referenced only by unreferenced expressions.
Delete Spreadsheet Data
Deletes all spreadsheets from the part file. To selectively delete the Gateway spreadsheet or the Modeling spreadsheet, use Tools tab→Spreadsheet.
Delete Visual Editor Data
Deletes Visual Editor data from the part file. For more information about the Visual Editor, see the Modeling Help.
Delete All Materials
Deletes all materials and textures applied to a work part.
Delete Duplicate Lights
Deletes duplicate visualization light objects from the part file.
Delete Invalid Part Attributes
Deletes part attributes that have invalid values.
Delete Unused Extract References
Reduces the size of pre-NX 11.0.1 part files with Extracted Body features by removing non-geometric references from the extracted geometry which are not used by any downstream features.
Reduces the part file size and memory usage of an assembly part file by removing assembly-specific changes to the color, translucency, and font of geometry in component parts. Select from the following options:
Take advantage of this feature during the spring, and every other season, to ensure your designs are clean and the best that they can be. Happy Spring cleaning!
