rotation in freecad

2017-04-17's week

Continue task of previous week to create video of y axis assembly based on script part 1

Tasks:

recreate video as Marcin suggests [1]
pay attention to details of video editing guidelines [2]

Results: Deliveries in a zip

Notes:

FreeCAD Python basics
- Change camera view with python console [3]:
  - get current position: Gui.activeDocument().activeView().getCamera()
  - set a position: Gui.activeDocument().activeView().setCamera('long text returned by previous get command')
- separate multiple commands in one line with ;
  - example: make carriage transparent: FreeCADGui.getDocument("D3D_Mini_Sub_Assembly_Axis_Y").getObject("Universal_axis_carriage_side_01").Transparency = 80;FreeCADGui.getDocument("D3D_Mini_Sub_Assembly_Axis_Y").getObject("Universal_axis_carriage_side_02").Transparency = 80
- Create a Macro script to change view during the playback then associate a hotkey with it associate an icon with a macro
Timing of FreeCAD's Exploded Assembly : I used only "Animation steps" parameter to adjust playback time. The duration of playback became longer when vokoscreen added some cpu load.

Time log : (I will sum up at end of week) 17 Apr: 1.5 h meeting
18 Apr: 1 hour reading (wiki contents), 2.5 hours struggling with the assembly video.
20 Apr: 2h20mins wiki readings + getting basics of freecad macro to set camera viewpoints and doing freecad exploded part animations with the freecad mini y axis created by Emmanouil.
21 Apr: 5:30 continue exploding in freecad + learn basic of video editing of kdenlive + put together the assembly video + upload files

Meeting notes: [4]
Manolis belt [5] How he assembled the CAD file [6]

2017-04-10's week

Task description:	Create assembly animation of Y Axis of D3D_Printer (script part 1)
Completion percentage:	69
Link to results:	incomplete files were removed

Hints

Install exploded parts module of FreeCAD and start exploring the exploded parts animations. If it freezes then install latest version of FreeCAD and the module itself.
The instructional videos of FreeCAD_101 are the good examples how it should look like: no major pauses, continuous voice
30 sec video should show 15 minutes of assembly which can be created in 1 hour. On the workshop each module will be built at the same time if someone completes his/her own then helps others. The instructional video will be played in a loop.
The bolts in the axis should all be M6x18, not M6x25
Link to meeting minutes within D3D_Log [7]
Jose has a 12" printer Jose_Log, CAD file can be downloaded from there. 10 April 2017 18.page suggests extruder realignment
If a part does not appear in part library Part_Library or in Emmanouil_Log then send e-mail to Marcin. To make things simpler the total amount of parts should not increase.
Exploded part helps with assembly [8] but the one on the link was not complete : missing some of the magnets. One carriage has 6 magnets : one on each corners and one on middle of long edges. Picture does not show everything but the description text of assembly details that. Magnets can be assembled with superglue and pushing for 15 minutes until glue hardens.
The modules ( Axis Motor Side - Chas, Carriage Side - Jean Baptiste, Idler Side - Roberto) can be used in the Y Axis video.
Every FreeCAD file should remain modifiable.

Open tasks / planned actions

create a short video how to use transclusion
Dimensioning Drawing Workbench tutorial: how to install, how to use to create language agonistic tutorials
how to use google docs to create language agonistic tutorials
edit wiki based on Development_Team_Checklist
debug exploded part animations bug, video details EPA grouping bug
assist with OSE linux improvements
spend time with experimenting building electic motors / generators, heating with Eddy-current effect
spend time with challenges of moulding plastic vs 3d printing it

to delegate / get training:

For the future we need to do another tutorial on Part Design Guidelines to make sure every part is created using proper procedures and an easy-to-modify strategy.

Time idependent structured blog

Organization
- Join OSE workshop Facebook group
- Signup to network.opensourceecology.org's 3dprinter developer group and ask questions there
- Join Monday meetings with chromium browser and Google Hangout, you can watch its recording on Marcin's youtube channel
- Use next week's Meeting agenda edit that, add a slide with your name in 'Scrum standup' section and log there what you did, which challanges you had and how you would like to continue
- Create a wiki page: log for yourself and link all the files you created (static content)
- Log your activity and time spent on it. Once a week before Monday's meeting upload it with Timesheet
- I removed the obsolete version of y axis assembly video from my youtube channel then realized that it broke the Workshopworkshop's page. I edited the workshop's page and updated the link to the new version of the video. The lifecycle is the following : several incomplete versions are shared then a final version is shared by contributor then the same video is shared by OSE youtube or vimeo. Mediawiki's transclusion can help to reference a permanent link which contains embedded code and version history. Link_to_d3d_y_axis_assebly_video {{:Link_to_d3d_y_axis_assebly_video}}

Eploded part animation videos
- install freecad 0.17 (0.16 is not stable and also addons installer is not part of freecad)
- install exploded assembly addon how to install FreeCAD modules
- you can reuse work of others for the video creation: most probably there are FreeCAD files already available on Emmanouil_Log or in part library Part_Library or you can ask on D3D network but you can create drawings from scratch
- See tutorial 1 tutorial videos 2
- Use Perspective view in FreeCAD (View / Perspective menu or just press P) for the videos
- pay attention to details of video editing guidelines
- save your freecad file frequently: once it freezes, you can return to the last save
- The instructional videos of FreeCAD_101 are the good examples how an assembly video should look like: no major pauses, continuous voice, exact timing, loud voice without background noise
- The assembly videos, created with FreeCAD Exploded animation module will be used on the bulid workshops: parts of the device will be assembled one by one meanwhile the assembly videos will be played in a loop.
- Upload the FreeCAD file which contians your work with exploded part animations to your log which should remain modifiable - to let others reuse your work
- Timing of FreeCAD's Exploded Assembly : I used only "Animation steps" parameter to adjust playback time. The duration of playback became longer when vokoscreen added some cpu load.

FreeCAD
- Bolts tool presented by Emmanouil
- You can add new parts to Part_Library
- log bugs here: http://opensourceecology.org/wiki/OSE_Workflow_FreeCAD_Bugs

Python
- Video Learn Python
- separate multiple commands in one line with ;
- Python book online

FreeCAD & Python
- Change camera view with python console source:
  - get current position: Gui.activeDocument().activeView().getCamera()
  - set a position: Gui.activeDocument().activeView().setCamera('long text returned by previous get command')
- Create a button with your macro script associate an icon with a macro
  - example python macro to make carriage transparent: FreeCADGui.getDocument("D3D_Mini_Sub_Assembly_Axis_Y").getObject("Universal_axis_carriage_side_01").Transparency = 80;FreeCADGui.getDocument("D3D_Mini_Sub_Assembly_Axis_Y").getObject("Universal_axis_carriage_side_02").Transparency = 80
- FreeCAD Scripting tutorial
- FreeCAD App Module full documentation, structure of application
- Language agnostic instructional creation needs a way to save a black and white picture
  - "If you want to change colors in 3D View you must change Line/Shape Colors of your models and background color too ." source
  - python command to save a picture with white background : FreeCADGui.activeDocument().activeView().saveImage('/tmp/a.png', 1024, 768, 'White')
  - macro which backups visibility of objects then hides all then shows specified and saves picture then restores visibility source
  - image workbench could be extended Image workbench FreeCAD wiki
  - official freecad wiki documentation does not reference saveimage link
  - FreeCAD has a built in Tools/Save picture... menu [11]
  - searching in freecad's source for saveimage Gui/View3DPy.cpp defines saveImage which calls writeToImageFile;
  - list methods of ActiveView object: dir(Gui.ActiveDocument.ActiveView) source
  - macro's print goes to report view (View/Panels/Report view) source
  - wireframe view with hidden lines would be the best - export to belnder then do the picture? blender hidden lines wireframe forum
  - wireframe with hidden lines in freecad: set all to black, lines to white then invert forum link

activeDoc = App.ActiveDocument
for obj in activeDoc.Objects:
     if hasattr(obj,'ViewObject') and obj.ViewObject.isVisible() and hasattr(obj,'Shape') and hasattr(obj.ViewObject,'ShapeColor') :
          activeDoc.getObject(obj.Name).ViewObject.ShapeColor = (1.00,1.00,1.00)
          activeDoc.getObject(obj.Name).ViewObject.LineColor = (0.00,0.00,0.00)
          activeDoc.getObject(obj.Name).ViewObject.LineWidth = 2.00


width, height = Gui.activeDocument().activeView().getSize()
Gui.activeDocument().activeView().saveImage('/tmp/test.png',width, height, 'Black'  )

- - how to workaround unhandled pycxx exception by wmayer source

Open the parameter editor (Tools / Edit parameters) and go to the group: Preferences > Document:

1. There create a boolean key DisablePBuffers and set it to true. Try again.
2. If it doesn't work set the value to false. Try again.
3. If it doesn't work create the boolean key CoinOffscreenRenderer and set it to true. Try again.
4. If it doesn't work then close FreeCAD and set the environment variables:
COIN_GLXGLUE_NO_PBUFFERS=1
COIN_GLXGLUE_NO_GLX13_PBUFFERS=1
Now restart FreeCAD and try again.
