Solid Trim Tool

Dave R

Jim's "Solids Trim and Keep" definitely makes it a lot easier although for creating mortises. I would really prefer it if the native Solid Tools didn't convert components to groups. It leads to much more work than cutting the mortises manually with the Rectangle tool and Push/Pull.

Plus it migrates the group to layer 0

Dave R

Trim and Keep does that, too.

TIG

To keep the layers unchanged edit Jim's script with Notepad or a similar plain-text editor, around line#81 you need to change this

def_to_keep.name = @model.definitions.unique_name(name)
grp = @first_picked.trim(@last_picked)

to this

layer=@last_picked.layer
def_to_keep.name = @model.definitions.unique_name(name)
grp = @first_picked.trim(@last_picked)
grp.layer=layer

The two extra lines saving/using the original's layer... so that it will retain the original layering of the now-trimmed-object.

Also, if you find yourself always purging the original unused untrimmed version, then you can further adjust the code, just before it says ' @model.commit_operation' insert these lines of code reading

if UI.messagebox("Delete Unused Definition?",MB_YESNO,"")==6
    def_to_keep.entities.erase_entities(def_to_keep.entities.to_a)
end
@model.commit_operation

On 'Yes' it will remove the earlier definition from the Component Browser's list after all instances of it have now been set to be ' new_def'... This will save you having to purge it later manually...

Dave R

Thank you TIG! Both of those work like a charm.

Without the plug in you can simply select the new group and explode it. After the explode, all the geometry is selected so you can right click and select "Make Component". Give it the exact same name it had to begin with and all is well.

That does work but it's extra steps.

TIG

Also you'd need to reassign the original layer manually [if you remembered it].

So Jim's tool - with my tweaks - means the trimmed component >> group is automatically made back into a component of the same name [including all instances updated], it's kept on its original layer, and you have the option of removing the now unused component from the browser or keeping it if you might like to reuse it somehow...

Dave R

And after exploding, you'd have to move the geometry back to Layer 0 where it should be.

I have a keyboard shortcut for Jim's plugin and now, with the modification it is absolutely painless for even the most simple trim operations.

Dave R

TIG, out of curiosity, assume that there would never be a need to keep the original version of the component. what would the code be to make the script automatically purge the unused version?

TIG

Remove the two lines ' if...' and ' end' at the start/end of the added code, so that the only thing you add is def_to_keep.entities.erase_entities(def_to_keep.entities.to_a) before the @model.commit_operation

Then there's no choice - the original object's shape is lost...

Dave R

Thanks, TIG.

If I were using other tools to do the same thing I would do with Trim and Keep I wouldn't have the original shape either. So far that's never been a problem.

TIG

OK...
If you ever need to delete a group/component in code you can use
* defn.entities.erase_entities(def_to_keep.entities.to_a)
or to be even shorter
* defn.entities.clear!
!!!

Calling it * def_to_keep is somewhat whimsical as it's the one to go !
Which is actually the same thing - but perhaps easier to grasp ?!
Always provided that it's inside a model.start_operation()...model.commit_operation block

thanks TIG, marked to come back and tinker with code later....

Seems like this thread is a more general topic than Woodworking. I was wondering if it should/could be moved to the SU Discussions subforum? Just a thought...

TIG

I've moved this thread into Plugins, which is probably a more logical home for it...
