Actually, I had hoped to be able to reach my goal more quickly by getting started with Assembly 4. With the exercises I have done so far, I am able to construct parts that can be used, for example, as transition pieces in exhaust systems. I started the application classically with a body and then a sketch. In other exercises I have created some other parts, all according to the procedure described before.
Now I want to use these parts in my exercises in Assembly 4 and stumble over the Part Container. In the videos I have watched on this topic again and again, this Part Container is used in different ways, which is already confusing. At first, I was happy to try my own exercises with the Part Container, without knowing what purpose the Part Container is supposed to fulfil.
Fortunately, there is still this FreeCAD Wiki. But this remark, found in the description of the Part Design Workbench,
does not really improve my understanding of the tools. The next sentenceStructure tools
These tools are in fact not part of the PartDesign Workbench. They belong to the Std Base system. They were developed in v0.17 with the intention that they would be useful to organize a model, and create assemblies; as such, they are very useful when working with bodies created with this workbench.
is a short nice explanation that can be accepted, but it lacks a deeper explanation. Two lines continue(Std Part.svg) Part: adds a new Part container in the active document and makes it active.
Ok, the use of body is familiar to me by now.(PartDesign Body.svg) Create body: creates a Body object in the active document and makes it active.
The hope for further explanations by a wiki for the Assembly 4 Workbench is unfortunately not fulfilled. So I have the impression that some tools are competing with each other:
Std_Part <--> Asm4_newPart
as well as
PartDesign_Body <--> Asm4_newBody
With the Asm4_newBody-tool, I have not been able to get a result so far. When using Std_Part-tool or Asm4_newPart-tool, I have not been able to find any differences either. But worse, so far my previous exercises have managed without using Std_Part-tool or Asm4_newPart-tool. What is the point of these tools?
