Assembly3 preview

[realthunder]

"/home/walter/Software/FreeCad/FreeCAD/build" was created by me as the build directory of FC.

In this case, you should move the asm3 directory into /home/walter/Software/FreeCad/FreeCAD/build/Ext/freecad/

moved (actually copied with cp -a)
$ ls /home/walter/Software/FreeCad/FreeCAD/build/Ext/freecad
asm3 __init__.py

$ ls /home/walter/Software/FreeCad/FreeCAD/build/Ext/freecad/asm3
assembly.py Gui LICENSE py_slvs_mac sys_slvs.py
constraint.py gui.py mover.py Readme.md sys_sympy.py
deps init_gui.py proxy.py slvs system.py
FCADLogger.py __init__.py py_slvs solver.py utils.py


But it does not get installed. Where is supposed to go after make install ?

How do you start FreeCAD? You can direct launch FC by running build/bin/FreeCAD, and in this case you'll see the asm3 workbench. I guess you install FC by "make install"? In this case, you need to find your user python site-package by running

Code: Select all

python -m site --user-site

It is usually located at .local/lib/python2.7/site-packages. Make sure there is a "freecad" directory inside, which I think should be created by "make install". If you don't see this directory, create it, and also create an empty __init__.py file. Then, copy asm3 directory inside this "freecad" directory, and then start FC.

Ok thanks realthunder,
now I have created the missing folder freecad in ~/.local/lib/python2.7/site-packages:

$ ls ~/.local/lib/python2.7/site-packages/freecad
asm3 __init__.py

And finally I have the workbench Assembly3.

Probably there is the need to add something into the cmake files so that these action are handled inside of the make install.

[fosselius]

I can confirm that you do not get a .local/lib folder after make install. I only have a .local/share. I am running Ubuntu 18.04

Code: Select all

maiden@horse:~$ python -m site --user-site
/home/maiden/.local/lib/python2.7/site-packages
maiden@horse:~$ ls /home/maiden/.local/lib/python2.7/
ls: cannot access '/home/maiden/.local/lib/python2.7/': No such file or directory

Here is the step-by-step how i got asm3 running:

Code: Select all

git clone https://github.com/realthunder/FreeCAD_assembly3.git asm3
cd asm3/
git submodule update --init slvs
cd slvs/
git checkout python
git submodule update --init extlib/libdxfrw
mkdir build
cd build/
cmake -DBUILD_PYTHON=1 ..
make _slvs
cd ..
mkdir py_slvs
echo "" > py_slvs/__init__.py
cp slvs/build/src/swig/python/slvs.py py_slvs/
cp slvs/build/src/swig/python/_slvs.so py_slvs/
cd ..
ln -s [ABSOLUTE PATH]/asm3 [FreeCAD LinkStage3]/build/Ext/freecad/
cd  [FreeCAD LinkStage3]/build/bin/
./FreeCAD

But why you do not simply add a "CMakeLists.txt" inside of Ext/freecad/asm3 directory which install all stuff into INSTALL_DIR/Ext/freecad
(or in INSTALL_DIR/Mod).

and, of course, the following line somewhere in Ext/freecad:
add_subdirectory(asm3)

This is the way all other module are installed. Why Assembly3 has to be installed apart in side of /.local/lib/python2.7/site-packages/freecad ?

Assembly3 is meant to be an external module, because of license issue. And FC new style python module is meant to be installable through pip, which I haven't add support yet, because not many people want to build the entire FC on their own, and there is pre-built image available. Those intermediate site-packages directory are supposed to be taken care of by pip.

[wsteffe]

Oh, I see realtunder, it seems a good idea to let it installable trough pip.

perhaps you could have put only the solvespace part in the src/Ext folder keeping GUI assembly.py constraint.py ... inside of src/Mod.
But may be you have done in this way because you consider Assembly3 as a simply wrapper of solvespace constraint solver.

Hello I am getting the folowing error message (repeated several times) inside of the Report view:
Show.TempoVis.isIn3DView error: No module named pivy

But all seems working well. Am I missing something ?

[kwahoo]

Hi,
Another report for the module:

AxialAlightment constraint fail to solve in some cases when two cylindrical faces are used to define the constraint.
