Another approach to assembly solver (A2plus)

[kbwbe]

- "Bottom Cylinder" plane with "Top Cube" plane (this one is easy and I got it right)
- "Cylinder" axe with "Cube" central axe (don't know how to create this one)

Hi @JieFK,
try to use "centerOfMass" constraint. This does exactly what you want. It aligns the faces and the central axes with one single constraint.

kbwbe Thanks, That did the trick.
Also on a more complex drawing, I used the same constrain, but not on the "thickness" plane, but rather on the two edges
Thanks again

Hi Guy's,

a small bugfix release of A2plus is out: V0.4.18

What changed ?
- on Ubuntu 18.04 LTS based systems (so also Linux Mint 19 series), the file dialog for importing parts was working case sensitive.
So *.fcstd files have not been proposed, only *.FCStd files. The new version now is working case insensitive for the file extension.

Hi guy's,

a new version of A2plus is out: V0.4.19

What's new ?:

- a new constraint has been added to A2plus with version V0.4.19

axisPlaneVertical: make an axis or a cylinder vertical to a plane.
This the button:

I made an engine and assembly with some parts and a script to run the animation. You can see the gif and the repository of the project.

Hi, I just wanted to show the gif

Dear kbwbe,

I'm trying to get involved in the A2p WB.
Since I didn't wanted to highjack this thread, I started a new thread on getting into the code of A2p WB: Assistance in fixing issue in A2p WB needed
But HarryGeier suggested to contact you through this thread. It would be great if you could give me some assistance. If it is in this thread or in the above mentioned I don't care.
Thanks a lot
toralf

Hi @toralf,

I'm trying to get involved in the A2p WB.

Thank you for your interest on A2plus.

Handling of transparency is still a work in progress and there are some issues.

When FC doc gets saved with transpareny off, all is ok,
but when FC doc gets saved with transparency on and FC
is closed and on the next call the A2P assembly is opened
the toggle of transparency doesn't work any more.

When switching to transparent mode of an assembly, the original colors/transparency values are saved to internal python data structures for recovery purposes, what you have probably already found when looking at a2plib.py.

Saving and closing the doc in transparent mode deletes the recovery structures and therefore the original transparency values get lost. Unfortunately ATM i do not know a working solution to prevent that. When there is some time, this part of code will be reworked again. Additionaly there seem still to be some issue of FC when loading transparent objects. Sometimes objects are shown non transparent after loading although obj.ViewObject.Transparency has a transparent value.

If you consider this workaround useful, I will make a PR for adding a Restore Transparency Button

Hi Maurice,
thank you for the PR, which i just merged to version V0.23. It is fore sure useful.

I also integrated a fix for this problem here: https://forum.freecadweb.org/viewtopic.php?f=3&t=36588

Thx a lot, Klaus
