Macro to delete tree features

[Dwight]

I'd like a macro I can use to select tree features and delete them. I do not want it to guess which ones I really want to delete, I would like it to go ahead and delete them without making a fuss. And it would be extra special if it did not delete tree features I didn't select.

Thanks

Dwight

So there's this, but it seems to delete only one feature no matter how many I have selected. I need some sort of loop?

'--------------------------------------
' Preconditions:
' 1. Open a model document.
' 2. Select the feature to delete.
' 3. Open the Immediate window.
'
' Postconditions:
' 1. Deletes the selected feature.
' 2. Examine the Immediate window, graphics
' area, and FeatureManager design tree.
'--------------------------------------
Option Explicit
Dim swApp As SldWorks.SldWorks
Dim swModel As SldWorks.ModelDoc2
Dim swSelMgr As SldWorks.SelectionMgr
Dim swModelDocExt As SldWorks.ModelDocExtension
Dim DeleteOption As Long
Dim status As Boolean
Sub main()
Set swApp = Application.SldWorks
Set swModel = swApp.ActiveDoc
Set swSelMgr = swModel.SelectionManager
Set swModelDocExt = swModel.Extension
' To delete absorbed features, use enum swDeleteSelectionOptions_e.swDelete_Absorbed
' To delete children features, use enum swDeleteSelectionOptions_e.swDelete_Children
' To keep absorbed features and children features, set DeleteOption = 0
DeleteOption = swDeleteSelectionOptions_e.swDelete_Absorbed

'Comment out the previous statement and uncomment one of the
'following statements to change how to delete the selected feature
'DeleteOption = swDeleteSelectionOptions_e.swDelete_Children
'DeleteOption = 0
'DeleteOption =swDeleteSelectionOptions_e.swDelete_Absorbed + swDeleteSelectionOptions_e.swDelete_Children
status = swModelDocExt.DeleteSelection2(DeleteOption)
Debug.Print "Feature deleted? " & status
End Sub

[Dwight]

This thing only does a folder full of features. Why a folder? Anyway, maybe I can edit that part out (maybe get rid of all the blank lines, too).

It's been too long since I've tried to do a macro. If this takes only a couple minutes for someone who knows what they are doing, I'd really appreciate it.

I'm not sure I understand what you are trying to accomplish Dwight? You want something that deletes what you selected, why not delete it "manually" by pressing "delete"..? Is it that it deletes other features in the tree? If so, you want to uncheck "Delete child features" in the delete confirmation box

I find that the manual delete function for tree features will do only a small subset of the features I select, and often it will delete features I don't select. If I uncheck "Delete child features" then it will delete even fewer features and still delete features I have not selected and do that unpredictably. If I select "Yes to All" it will do more but far fewer than all.

I do injection molded parts and often have a long feature tree. Also I do concept development for new parts, often new products, so I often want to hack away huge chunks of features while I try to preserve a set of features late in the model. This morning I was doing just this and could only get there in about 20 steps. And that doesn't count the times I had step backwards and try again in order to prevent the features I wanted from disappearing. It is really quite frustrating.

I can't imagine more people don't complain about this. If what I describe here doesn't seem realistic, I could make a video of it.

That's intriguing, I'd love a video of the issue or a sample part that I could test to see if I get the same result on my end, I don't think I've ever had things selected to delete not be deleted

[AlexB]

I don't necessarily see an issue with your macro, other than it operates the same as the delete dialog from within SW when you manually try to delete multiple things.

The main issue is when you try to delete a feature and another feature that is dependent on the one being deleted. This, for whatever reason, causes the delete dialog to de-select the conflicting items.

The best I could recommend is to go through one by one and try and delete it as a single selection. See below for modified macro code:
Disclaimer: I didn't test this much so it could still break in some scenarios

Code: Select all

' 1. Open a model document.
' 2. Select the feature to delete.

Thanks very much. It is kind of slow, but that's fine because it doesn't stop for prompts, which means I can go do something else while it's working. Very useful.

Dwight

[AlexB]

It is kind of slow...

I suppose it probably rebuilds between each delete, which is not really fun. The attached version listens for events to halt rebuild during deletion and only rebuilds once at the end.

[Dwight]

AlexB

The second version didn't seem to run. In the editor, it didn't compile. I've no idea why, since the "swApp As SldWorks.SldWorks" looks the same as in your first version. But I don't know what I am looking for.

I made a video of my experience with deleting.

You would need to change the macro reference libraries to suit your SW version. Check this video

Thanks, Deepak. That worked fine.

And thanks very much AlexB. This will save me a lot of frustration.
