sketches, parts, subassemblies and final ...

Postby crownfield » Thu Oct 04, 2018 12:16 am

ok

so every one can get perspective.
In windows 7, back to version freecad .16,
cause .17 just does not do what it says.

I want to sketch / build parts,
and then assemble them into sub-assemblies,
and then into a project.
I think it will have about 10 parts.

I have created a 2x4 cross section.
it is now a solid, 2x4x36. ( part one)

how do I define and use this as a part, and assemble parts?
subassembly is not defined.

in a sketch, no choice of adding a prior part as far as I can see.

where does assembly of parts happen?
should search be able to find this?

yes, I checked / searched help, and 'assemble parts' of course gets no hits, except python scripting.
sadly, help so far is batting the low single digits.

(most of the answers are like behringer manual.
if you copy step for step you can not get where they get.
they leave out critical assumptions. their support knows this.)

Roland had some good videos on youtube for 0.16. Sadly, he's no longer with us, but his videos live on. I think he had one or two on using Assembly2 workbench, too. Look for the "LearnFreeCAD" channel on youtube.

thank you.

does that mean there should be a chapter in the manual
about sketch - part - subassemblies , and it is missing?

big primary concept should be well documented.
so far, not a clue in freecad.

videos? when you read and can use indexes,
videos are very slow, and take a long time.
I prefer reading and searching indexes.

I suspect that "assembly 2 workbench" is going to be hard to find.

There is no chapter in the manual, because Assembly2 is an addon workbench. It is not part of the FreeCAD core. All I found is https://github.com/hamish2014/FreeCAD_assembly2/wiki , but if you search the forum for Assembly2 you should find more.

Besides that, 10 solids can be managed very well in 0.17/0.18. User ppemawm has shown and commented several of his models, e.g. https://forum.freecadweb.org/viewtopic. ... 50#p252269 .
You can have one body for each solid and arrange these bodies. Very straight forward concept.

I like watching videos, but each to his own. The one I made on extruding that sketch was only 2 minutes long. You should go back and watch it if you haven't already. Might help, might not, worth a shot. It seems like Roland made a table in one of his videos, but I could be mistaken about that.

Hi @crownfield

FreeCAD 0.17 didn't yet bring any assembly capabilities (for adding parametric relations between parts) by default. For now modules like Assembly 2, A2Plus and Assembly 3 are the ones providing assembly capabilities for FreeCAD.

that sounds like what I needed to know.
big missing part.
seems like it needed to be part of the original concept.

For my Sub-Assemblies, I use a 'Part' (the yellow stair-step Icons)
For Parts in the Sub-Assemblies, I use individual 'Bodies' (the blue stair-step Icons). These are also individual parts comprised of Features (Pad, Cuts, etc).
The Assembly and Sub-Assembly can also contain other items such as imported .STL, .Step... (the Green icons)

Example: The 3DPrinter I made for my Hacked printers.
It's a File with 'Parts' (renamed) that contains several Sub-Assemblies ( Bodies renamed) including imported Stl files
Also contains individual Techdraw drawings.

As a follow-up note:
This week I designed an adapter for a low-cost Metal Feed-Arm I found on Amazon.
Updating the Assembly to include the Adapter, Metal-FeederMount and a FeedPort was simple. It's all about Datum's.
And, knowing what Origin/Planes to use. That's the part that will take a bit of playing with until you can move stuff without loosing references used to design them...

The difference between this image and previous one is the addition of the new parts and the raised height and offset position of the motor

Good luck
