Assembly2 Workbench/pl

Introduction
Assembly2 is an assembly workbench for FreeCAD v0.15 with support for importing parts from external files.

As stated by its author on the forum, it is no longer maintained since 2016, therefore it may have issues with FreeCAD 0.17 and above. The newer and actively maintained A2plus Workbench is a good alternative.



Usage
Intended work-flow:
 * each part in the assembly is designed in its own FreeCAD file
 * a separate assembly FreeCAD file is created
 * parts are imported to this assembly file using the Assembly 2 workbench
 * spacial constraints are then added to assemble the imported parts

Features
 * circular edge constraint
 * axial constraint
 * plane constraint
 * part importing
 * updating of parts already imported

Limitations
 * Poor constraint solver which may fail or take excessively long for complicated assemblies
 * undo and other similar features not supported

Tools
Toolbar

Automatic installation
This workbench can be installed from the Addon Manager.

From GitHub
To use this workbench clone this git repository under your FreeCAD Mod directory, and install the pyside and numpy python libraries. On a Linux Debian based system such as Ubuntu, installation can be done through BASH as follows

In FreeCAD you will now have a new workbench-entry called "Assembly 2". Once installed, use git to upgrade to the latest version through BASH as follows

Alternatilvely, on an Ubuntu system the freecad-community PPA can be used:

In Windows
 * download the git repository as ZIP
 * assuming FreeCAD is installed in "C:\PortableApps\FreeCAD 0_15", go to "C:\PortableApps\FreeCAD 0_15\Mod" within Windows Explorer
 * create new directory named "assembly2"
 * unzip downloaded repository in "C:\PortableApps\FreeCAD 0_15\Mod\assembly2"

FreeCAD will now have a new workbench-entry called "Assembly 2".

Pyside and Numpy are integrated in the FreeCAD 0.15 dev-Snapshots, so these Python packages do not need to be installed individually

To update to the latest version, delete the assembly2 folder and redownload the git repository.
