Change Assembly Part Attachment?

I can't seem to change the attachment point of a linked part after initial attachment. The attachment inter face that comes after clicking the link part button doesn't seem to be accessible from the created part. On the linked part in the 'Assembly' property group, I've also tried changed the 'Attached By' parameter. This doesn't seem to work. Is there some feature I'm missing or should I report this as a bug?

did you try the "Place Link" button ?

Interesting tool! In my case this works with sub-assemblies and even "binder of a binder". Thank you!

Hello, Zolko again!
Recently I've made a project of a garden furniture bench in ASM4. This bench has a metal frame made of welding tubes 25x25x2 and 40x25x2. The wooden cover consists of boards 90x27x1200, which are attached by bolts M8x40 through the sheet metal (2mm) stripes. To test the possibilities of new BOM tool from amazing FarmingSoul (https://github.com/Zolko-123/FreeCAD_As ... issues/118) - I've made a 8-bench assembly - and must say - it counts cool! Unfortunately the whole 8-bench assembly view is lagging, but the BOM is working good///

Thank you very much for ASM4!! 8-)

P/S/ In every arc tube there's some reserve for metal rolling machine (+300mm)

i have made a assy of a hot end on a carriage for a 3d printer
and am wanting to design a cooling duct around the
hot-end attaching on to
the carriage with
an attached fan
each peice is an instance in the assy

can i design the fan shroud on top of the assy
if so how do i go about doing it

I hope you realise that it's impossible to answer your question

ill be more specific
I've tried using shape binder to get a point from one of the assy parts to put into another new assy part
which doesn't work

right now i am zooming into a point in the assy and putting a reference point in by eye, at the point of interest. then using that point to draw over

i am looking for a way to get a point ,line ,plane, shape data or any other data , from one part of the assy and put it into another part so that i can design over the reference points.

i have 40+ years of cad experience and 4 weeks of FreeCAD experience
any help would be apreciated

the command importDatum() might be of interest for you: it allows to import a datum object (which can be a datum point) from a child part into the root assembly. But it only allows data transfer in 1 direction (child → assembly) because of circular dependencies.

You can also try the new SubShapeBinder function:

If you want to design 2 parts that are dependent on each other, you should design them in the same file, but still import them as separate parts into the assembly. This functionality (to be able to design several Parts/Bodies in the same file and still have independent links) is extremely powerful and doesn't exist in other CAD systems
