Re: Assembly3 preview
Not exactly sure which action you're referring to, but Element is not Link. It is more like a shape binder. It has its own shape. You can even deliberately detach an Element (right click tree view item and select action 'detach') from its source. It will retain its shape, and the assembly will still work.HoWil wrote: ↑Mon Nov 15, 2021 12:51 pm Dear realthunder,
Is there a way to redefine a broken Element? Currently in Combo-View under Link->Linked object the button 'change linked object' is 'grayed-out'/disabled.
It would help a lot if one could redefine the linked face/element after faces were messed up with topo-renaming-problems!
BR,

And that's why you cannot change element's linked object and the option is "greyed out"realthunder wrote: ↑Mon Nov 15, 2021 9:59 pm ... but Element is not Link. It is more like a shape binder...
but... perhaps what is confusing, is the fact that the option to "change the linked option" appears even though it is not possible to use it.
I personally get used to idiosyncrasies of FreeCAD and move on...
Re: Assembly3 preview
So, if one can change or repair an element by drag-and-dropping a new element onto it, why can't I change it from within the combo-view (as shown in my last post).realthunder wrote: ↑Mon Nov 15, 2021 9:59 pm [ Not exactly sure which action you're referring to, but Element is not Link.

Re: Assembly3 preview
I see. You meant to directly edit the 'LinkedObject' property. It can still be done if you really want to. Right click this the 'LinkedObject' and select 'Show all' and then uncheck 'Read Only'.
But, I would advise against it. The Element is a very important concept in asm3. It has special requirements on its linked object, especially for the the element of a sub-assembly. It is not supposed to directly reference any models inside a sub-assembly. It will only indirectly reference it through the element in that sub-assembly. When you do drag and drop, it will automatically create one in the sub-assembly if there is no corresponding element, and recursively do so if necessary.
Re: Assembly3 preview
Hi.
I think you may want to consider using MBDyn as a solver for the Assemby3 workbench. MBDym is capable of solving complex assemblies. An approach to use it for an assembly workbench may be to use only static (massless) nodes and define any kind of joint required (in-line, in-plane, prismatic, etc...). Then launch MBDyn and position the CAD parts where MBDyn says they should be in order to satisfy the constrains.

Re: Assembly3 preview
what's the advantage over the current solver?
Re: Assembly3 preview
RealThunder, if I find genuine, reproducible issues with Assembly3, do you prefer if I report them directly to your github, or do you prefer if I raise them here instead (or both?)?

Re: Assembly3 preview
I get a weird bug and a crush on both Linux and macOS when I try to move whole object tree to a new body. Let me know if there is a way I can provide more information.

Re: Assembly3 preview
I prefer issue report on github. Thanks.
