To cover assembly 4 topics, a new thread called Assembly 4 workbench has been started and is hosted by @Zolko at:
Please do not post here.
Thank you. Dan.
Assembly 4 is based on the idea of placing parts in an assembly by using the LCS, Local Coordinate Systems (called Csys in Catia V5) of the parts where as A2plus and Assembly 3 uses constraints to place the parts. The idea was Introduced by Zolko who felt the rebuild times would be less than using constraints because constraints require mathematical solver processing time whereas the LCS is built into the part.
Zolko: Statement from Feb. 24,2019
"Assembly 4, was assembly without solver, you can download it below, to be extracted into ~/.FreeCAD/Mod. It's not as sophisticated as A2+ or A3, but it allows to assemble hundreds of parts quite easily. It's more like a proof-of-concept actually.
Asm4 "https://github.com/Zolko-123/FreeCAD_aw ... 4_v0.3.zip
In order to use Assembly 4 you must use realthunder's Asm3 AppImage. App::Link is only available with that (or your self-compiled LinkStage3 branch)
Asm3 available here: https://github.com/realthunder/FreeCAD_ ... 3/releases
Step by step instructions:
- take a piece of paper, draw your boxes (yes, I'm not kidding)
- decide what are the functional elements of your boxes (corner, middle-point, hole ...)
- once that's done, fire-up FreeCAD (but really only after you have done the previous points !)
- new document → new part → new sketch → draw sketch such as where you would want the previously decided reference points to be. If necessary, make several sketches
- save your document as asm_2boxes
- new document → new part → new body → new sketch → draw a rectangle of approximate size → extrude that rectangle → save document as box 1
- create some LCS where you think you want your previously decided reference points to be
- repeat for box 2
- in asm_2boxes, insert box1, place according to the LCS
- repeat for box 2
- now that you know how your boxes are going to actually be assembly this way, modify them. Create new LCS if necessary. Don't design any details until you're satisfied with the way the boxes fit together.
- swap between assembly and part to check that you are going into the right direction
- Go into more detail of the boxes' design, and, if necessary, create a new (second) body, which is going to be your real part.

there are 3 new WBs for assembly

I know of Assembly3 and A2Plus. Which is the third one?

Another Assembly work bench seems available. I downloaded the files and started the workbench. I have attached a picture of the Icons and a dialog box that showed when I clicked on the "Insert a external part" icon. There is a read me file in the Assembly 4 directory but I haven't had a chance to read it yet. This all I know about Assembly 4.
I found this information by reading posts in the "Assembly3 preview" thread. The posts are dated Feb 24 through March 1 2019.
