Changes doesn't affect clone

[brusk]

Hello forum!

I can't find out how to clone properly.

As a test I have created a sketch in Part Design and made a pocket feature.

I then cloned my pocket feature and moved it a bit so both are visible.

So far so good. Now I created a sketch with a circle and padded that on my original object. That change does not happen on the clone as I thought.

If I make changes to the original sketch from which I pocket'ed in the first place the change is reflected on the clone though.

How is it supposed to work? On the wiki page it just says " If the original object changes, the clone changes too, but keeps its position, rotation and scale"

Hello,

That change does not happen on the clone as I thought.

It won't, because the clone is based on the Pocket feature. If you add other features you need to create a new clone based on the last Part Design feature in the tree.

Thanks. I'll just have to delete and re-clone if I add to the original I guess.

If there's something else depending on the clone, you may want to update the link in the existing clone. It can be done with OpenSCAD ReplaceObject tool from OpenSCAD workbench. The wiki page is empty, just read the tooltip in FreeCAD.

Note that it is also possible to simply change the "Objects" property of the clone, to make it point to the new object, but at the moment this cannot be done from the GUI, only via python (change the code below to use the actual names of your objects):

Code: Select all

FreeCAD.ActiveDocument.Name_of_your_clone.Objects=[FreeCAD.ActiveDocument.Name_of_your_new_object]

Thanks yorik and DeepSOIC!

That's some power tips. I'm really glad it's possible to use clones in a more parametric and non-destructive way .

I thought I'd be caught by this, but it seems that issue has been resolved. I was caught by something else - the clones only show down to the current tip setting in the original.

Just for completeness, I am prettey sure I read on the documentation somewhere that Linking objects is more efficient than cloning.

I just created a body and made a link to the body.

then I can add features to the body and the link get's updated instantly, no need to redefine it's source.

I think this is what you wanted
