Manipulator WorkBench

Hi @hammax
the Caliper is working in the same philosophy of the DSM Caliper: you get fast measurement for 3D parts

Please have a look at this diskussion:
https://forum.freecadweb.org/viewtopic. ... 0&start=20

no problem at all ... you cannot patent a user friendly way to work with a sw ... I just simplified the way to use the gui: click on an edge and get the measure...
In the past someone tried to patent double click to block other developers, but this was a useless effort

Hello. Thanks to Chris_G, I succeeded to create an "handle" in the graphic window.
Attached an example macro with the parent class that can be customized.
Run it in FreeCAD with few objects in an open viewport. Follow the hints in the Report panel to move the objects.

handle1.py

example for moving objects in viewport

It' a little "barbarian" yet but, as said some time ago, I hope it can be usefull for Manipulator WB.

Hi,
I tried the macro in FC0.17 and it doesn't work...
In FC0.16 I get a big arrow compared to the main object(s) ...
this arrow can be clicked to get user mouse input...
but if I press 'Esc' as suggested both in FC0.17 and 0.16 I get:

Unhandled unknown exception caught in GUIApplication::notify.
Unhandled unknown exception caught in GUIApplication::notify.

I'm on Win10 64b

Thx
Maurice

Alas!
It worked fine for me (gnu-linux32), but as explained in this thread i also got some trouble to make it work at first.
https://forum.freecadweb.org/viewtopic.php?f=22&t=25100
Actually I also used the trick of referencing an object inside a function before creating it: maybe it doesn't always work.

I'll search a different way.
Let me have the logs of your error (for example running FC from the prompt C:\freecad -l, or something like that): maybe there's an hint of the cause of the trouble.

This should work.

macro updated

In fact I tried to run the previous version of the macro in Windows (Vista-32bit) and got your same error. Now it works on both systems for me.
I think that the "ESC" problem deals with how the different OS implement the functions of pivy related to callbacks, so I bypassed the problem creating a dialog to exit the command.

I refined a little the code: now the arrow size is scaled automatically to the average length of edges of the objects selected: so no more "huge" arrows on the screen.
Also the direction and displacement depends upon the faces or edges selected. By the way: remember to select the objects to move before running the macro.

On the code side, I had to import some stuff from the flamingo WB code (so check that the add-on is available in your FC).
Chiefly, a new version of the "arrow" class: I included this latter in the same code of the macro because I did not update the repository in github yet.

So, it's still "barbarian" but usable: it's handy to move quickly objects in the viewport.
I hope it could be of help to create something similar and more easy-to-use in Manipulator WB.

Hi maurice,

Is it possible to use your manipulator-wb to move an object from anywhere in 3D to e.g. 0,0,0?
Please see the attached file and the picture to see what I want to achieve.

THX, I succeeded with draft-move. This did not work because the compound was somehow corrupt. I simply rebuilt it and now it works.

Hi @HoWill,
good to know you made it

Just because I am curious: Would it be possible with use manipulator wb for such task or is draft-move the only chance? This would help because one would have to switch wbs once less.
