The recommended way to install A2plus is via FreeCAD's Addon Manager under the Tools → 'Addon Manager' dropdown menu. Some work is being done to address this in future releases of FreeCAD which will improve this behaviour. This phenomena is seen in many proprietary CAD solutions. This behaviour is due to FreeCAD's lack of Topological Naming and is difficult to correct at the moment. You should delete constraints of parts before reimporting them.Īfter that please constrain these parts again. Known IssuesĪ weak point is, and is similar to Assembly 2, updating / reimporting parts from external files.Ĭonstraints will break. There are prereleases available, please browse the releases section of this repository. You have to assemble existing projects again. A2plus would have to handle everything in same way as Assembly 2, including bugs, exact orientations, etc. Some new small features as visibility helpers (isolate and show only selected parts, transparency of whole assembly).No collision check of parts at moment.No animation for degrees of freedom, as difficult for new solver type.Different and in future more constraints, internally with different names. A new designed solving algorithm, able to solve some more complicated relations.Same as Assembly 2 it mainly aims at importing external files to the assembly.The workflow and the UI, so users of Assembly 2 can use it in an intuitive way.A2plus can be used with FreeCAD from v0.16 including support for importing parts from external files. This project started as a fork of Hamish's Assembly 2 workbench (development on A2 went dormant and was unmaintained for a long period). It is still under development and experimental at this moment but is showing some potential. Using the KISS principle: KEEP IT SIMPLE, STUPIDĪ2plus workbench tries to implement a new constraint solving algorithm to avoid some problems that occurred with the original solver. The main goal of A2plus is to create a very simple, easy to use, and not over-featured workbench for FreeCAD assemblies. Another assembly workbench for FreeCAD, following and extending Hamish's Assembly 2 workbench hence Assembly2 plus.
