By all reports, this is going to be an amazing feature just dripping with awesome sauce. In the meantime, if you want to design anything with multiple parts, your options are pretty limited. You can certainly design multiple parts in the same file but this causes problems if you need two instance of a part for the assembly. You can select a pad object and duplicate it, but the duplicated part will not be linked to the sketch so any downstream changes will not be incorporated into the duplicates.

FreeCAD is no exception. Both import and export have worked flawlessly for me. Repeat for the other parts too.

Note: I use the same name as the file and the extension. Now in my project directory I have bulkhead. If I make changes to the part, I have to export again. Switch to the empty assembly file and import the. This is just the reverse of the previous step. The import dialog will let you select multiple files at once and import them all.

This is nice. Once the parts are imported, you can adjust these properties. Once imported, the step files will behave like other objects.

You can run boolean operations on them, adjust colors, make them invisible, etc. In my example, I need two ductingbracemounts. The duplicate will be in the same position as the original so it will be invisible until moved. Hi there. I have not even peeked at the assemble function and really appreciate your documentation on that! If you open Project A and Project B. Oh, I dont know if this works in 0. I used to use the same kind of trick in HeeksCNC for cutting and pasting machining operations. I ended up with exactly the same workflow as yours.

Since the original parts are modified every few days, I wrote a script to rebuild my assembly from the step files to try to save me some work. Although you can merge projects in FreeCAD. BTW there is another placement tool available in v0. You can also use the Draft Move command, provided you have a planar face to set your working plane to beforehand. Hi Sliptonic, do you happen to have a 2D vector file for the 3 main outside frame parts which you modified from the original design to avoid bending the plastic such as a.

Quite a hard work, but successful. There are a number of good tutorials on using the functionality but you still have to build it from an alternate branch in the git repository.

This assembly workbench allows to integrate into a single container under a single coordinate system other FreeCAD objects and place them relative to the assembly and to each-other. The parts that are linked can invariably be in the same document as the assembly or an external document. In particular, it can be inserted into another Assembly4 Model to create nested assemblies.

It can also contain solids and datum objects. An Assembly4 Model can be a stand-alone part, an assembly, a sub-assembly, and any combinations of these.

No geometry is used to place and constrain parts relative to each other, thus avoiding a lot of the topological naming problems. Please Note: objects in the same document as the linked part but outside the App::Part container will not be inserted.

Please Note: only Part and Body containers at the root of a document can be inserted. Objects inside containers cannot be used directly by Assembly 4. It is called Assembly4 in the Addon Repository.

Latest commit.Privacy Terms. Quick links. Another approach to assembly solver A2plus Discussion about the development of the Assembly workbench. I developed a small prototype of yet another solver. But it can easily be extended. It consist only of one file, which is attached.

The base concept is inspired by physics. Forces Distances from point to targetpoints will cause moves and rotations around a spin-center. Also axis-alignments will cause "torque" and cause spinning around. The solver is working iteratively. It is just a prototype and many things are still missing. But the idea seems to work. Have a look a the following to tests which i did. You do not have the required permissions to view the files attached to this post.

Last edited by kbwbe on Tue Jul 10, pm, edited 2 times in total. I see your work is somehow inspired by Assembly 2 workbench? Do you plan to create a new workbench? What you attached is i guess only a prototype of a potential solver? I would say create a workbench or extend the Assembly 2 workbench and see how that goes. If it will be able to assemble FreeCAD geometry in some straightforward way i am sure end users will use it. Your are right. I am working with a refurbished assembly2-workbench.

I like the base concepts of it very much and did some bigger projects with it. I use it everyday.

Unfortunately I have some problems with fc0. Therefore i started this work with new solver and integrated it into my workbench.

Hamishs algorithm to recover the indexes is slow and fails very often.In FreeCAD the word " Assembly " is normally used to refer to a 3D model that is composed of several distinguishable parts, that are put together in some way to create a functional object, just like real life products are made. For example, a bolt, a washer and a nut are three separate bodies that when put together comprise an assembly.

Left: three individual contiguous solids, each of them modelled by a PartDesign Body.

Right: the individual Bodies put together inside a Std Part to create an assembly. In general terms, you don't need special tools to create assemblies, you just need to have many different bodies arranged in some way. You may use one of the pseudo-assembly external workbencheslike Lattice2, Manipulator, Part-o-magic, or WorkFeature, to help you find intersections, measure distances, and distribute your objects in the desired way. In general, the Std Part object was designed to serve as the basic building block to create assemblies.

This object is used to group several bodies and move them together as a unit, that is, as a sub-assembly. Then this sub-assembly can be placed next to, or used inside of other sub-assemblies in order to create the final assembly.

You can also use a dedicated assembly workbench, like A2plusAssembly3or Assembly4. Please note that Assembly2 is unmaintained, so it is not recommended for new models. The assembly workbenches use constraints and expressions to create relationships between the objects in your model, in order to mathematically tie the objects in place, for example, "this face should stick to this other face", "this cylinder should be concentric to that circle", "this point should follow this edge", etc.

This is an advanced usage of the software that is normally used in complex mechanical systems. If your model is not very complex, then using an assembly workbench may not be necessary.

As of FreeCAD 0. Assembly workbenches are difficult to program because many problems need to be solved regarding the efficient use of bodies and parts in your model. Nevertheless, the introduction of the App Link object has improved the situation. Please note that assembly workbenches are generally incompatible with each other. If you create an assembly with one of these workbenches, you should stick to it, and not use another assembly workbench to work with the same document.

The assembly workbenches continue development, and it is expected that at some point one assembly workbench will emerge as the "official" one.

This could happen by promoting one of the current assembly workbenches, or by combining them to produce a more complete solution. Other languages:. Navigation menu Personal tools English Log in. Namespaces Page Discussion. Views Read View source View history.

Discussion about the development of the Assembly workbench. It may be difficult to abandon well programmed functions and beloved concepts, but it will not get better if you do so in a year or so. For the FreeCAD community it would be phantastic to see you walk into one direction!

Re: Assembly3, A2plus, Assembly4? What are the problems we want to solve? I'd rather suggest to list some typical use-cases, and try to solve them with the available tools. Then we can talk about the relative merits of different proposals. There are other people doing funny quasi-assembly stuff that you didn't list.

I'm not even sure that 1 solution to rule them all is the best possible outcome. Would you — and everybody who feels concerned — try to list use-cases and typical scenarios for an assembly workbench? I actually incorporated some of Zolko's idea into asm3 with the 'Placement' constraint, and I supported his asm4 as well.

I actually plan to take a look at a2plus solver when I have time. It's just that there are other more important things to do first. Try Assembly3 latest version 0. And if you'd like to show your support, you can donate through patreonliberapayor paypal. I guess, nobody is keen to check a really large assembly for correctness by visual inspection Newbies will most likely prefer very small projects, with emphasis on small aspects of a design.

At least I would, as I am quickly overwhelmed by a large, complex example. I am currently working on a larger design, but concentrate on a small fraction of the technology, Realthunder's Link, and expressions to define the relationships between objects in the design. When done, I'll try to recreate the design with Assembly Constraints, just to see if and how the solver engine kills performance. Then again with Zolko's Assembly 4 approach, which I regard similar to what I'm currently doing.

If asked for my two cents, I'd suggest to - let the different assembly workbench projects stabilize, - then evaluate their strengths and weaknesses ease of operation, functionality, performance with large designs, stability with respect to design changes topo naming…- then discuss how to proceed. Then we can choose the technology that best fits the project. Which must be robust, suitable for a lot of different tasks but not unneccessary complex.

And we are stuck with them unless a complete redesign from the ground up happens as Blender 2. Everything else is on top of that.

It would be nice to have a working and polished assembly workbench but it should not exist just to have it.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Assembly3 workbench is yet another attempt to bring assembly capability to FreeCAD.

There is the original unfinished Assembly workbench in FreeCAD source tree, and Assembly2which is an inspiration of this workbench, and with some code borrowed as well. The emphasis of Assembly3 is on full support of nested and multi-document assemblies.

Assembly4 Workbench

Feel free to show your support, and thanks in advance! Although Assembly3 workbench is written in Python, it depends on a few external python extensions. In addition, it relies on quite a few FreeCAD core changes to work properly. At the moment of this writing, these changes have not been merged into upstream yet, and only exists as a forked branch.

If you want to build everything yourself, please check out the build instruction here. You can find more details at here. Before starting to use the Assembly3 workbench, it is necessary for the user to be familiar with a few new concepts introduced by the forked FreeCAD. You can find instructions on common operations along with some tutorials at here. This section is for those who have used Assembly2 before.

Here is a brief list of comparison between Assembly2 to Assembly3. Assembly2 supports only one assembly per document, so the document can be considered as the assembly container. Assembly3 has dedicated container for assembly and supports multiple nested assemblies per document. Assembly2 has dedicated object for imported child feature. The child feature's geometry is imported as a compound, and can be updated by user in case of external modification of the geometry model.

Assembly3 has no special object for imported feature, although the feature may be added through a link under some circumstances. Simply drag and drop feature into an Assembly container, even if the feature is in another document. Any modification of the feature is instantaneously visible to its parent assembly. The FreeCAD core provides various commands to help navigating among nested assemblies and the linked child features, import the external feature into the same document of the assembly, and export the child feature into external document.

In Assembly2, the imported child feature acts as a container to group related constraints. There is no visualization of the geometry element in the constraint. The Assembly3 constraints are grouped under the parent assembly, each constraint acts as a container of its referring geometry ElementLinkwith enhanced visualization support.Create your free GitHub account today to subscribe to this repository for new releases and build software alongside 40 million developers.
