Batch Purge of ipts?

[estringer]

We are having issues with large assemblies crashing when opening. Autodesk has told us that the large file size of our parts and sub-assemblies is contributing to this issue. Is there a way to batch purge parts and assemblies within Inventor or does anyone know of iLogic that might accomplish this? I am under the impression from my research that the Task Scheduler only purges styles.

Task Scheduler

From what I have read, I am lead to believe that this only purges styles. Is that not correct?

[Frederick_Law]

I believe so.

What else you want to "purge"?

Purge unused?

[estringer]

Yes.

[Frederick_Law]

I don't think you can skip the dialog box.

It doesn't have API calls.

Also it didn't delete User Parameters.

Are any of the parts imported from step files? If they are then deriving the parts and reducing the detail is one good way to reduce file size. 

[estringer]

None of the parts are from STP files.

@estringer I'm sure Autodesk has advised you of this but have you tried using Express Mode for these assemblies? 

[estringer]

@tfrohe_LSI ,

I can typically get the larger assemblies to open in Express mode, it is opening in full when they crash.

[A.Acheson]

Have you been able to narrow down what is ballooning the filesize? Without knowing the scale of what your working with is can be difficult to help in this situation. If the assemblies are just too big then you might have no option but to derive and simplify them to a part and have them as complety seperate files and drawings.

@A.Acheson ,

Our templates have a lot of items built into them initially that could be cut out after they have been through checking. That is contributing heavily to the file size and what is driving my request for a method to purge unused items.

[A.Acheson]

Can you define the objects items, Parameters/iProperties?

[estringer]

Sketch blocks, parameters, pre-built sketches. We wait until after most of that has been defined before adding iProperties so that isn't contributing wastefully.

[A.Acheson]

To delete sketch blocks you can probably try the nuclear method and just delete them. If is associated to a sketch it will error out. Do Try this in a trial part to ensure it doesn't mess up your parts. 

Dim partDoc As PartDocument = ThisApplication.ActiveDocument
For Each sktBlock As SketchBlockDefinition In partDoc.ComponentDefinition.SketchBlockDefinitions
          Try	
           sktBlock.Delete
          Catch
          End Try
Next

	

And here is a post to delete the parameters
