Re: Fedora 15 - missing libraries

I tried to compile the svn branch Version-0-11. I didn't find any soqt.i there. I'm actually really confused with the fact that the pivy sources are included in the FreeCAD sources. And even more confused that two versions are included (even a version 0.5.0, when Pivy is offically at v0.3.0). I trie...

Re: Fedora 15 - missing libraries

Hi elixis, thank you for the info! After having written my last post, I tried to compile, ignoring COIN_VERSION3-NOTFOUND. I had a problem related to SoQtSpaceball.h. I notice that you did something about this missing file. I'll also try. It's a pity because I do have a spaceball and wanted to try i...

Re: Insert a human in FreeCAD ?

Hi Emmanuel, if you want to move the body part, the best is to use the Robot Workbench. However, some programming is needed since, as for now, the Robot Workbench supports only 6-revolute-axis robots. A little C++ programming is needed to generalize this to n-axis robots. Then, you would need a vrml...

Re: TODO for sketcher

Hi, about colinearity and tangency for line segments. There is indeed a difference. For colinearity, the four points of the two line segments must be aligned, for tangency the two line segments need to have a common point. I don't think colinearity is useful because it can be achieved with paralleli...

Re: Mise en Plan

Bonjour, le problème vient peut-être de "App.ActiveDocument.ActiveObject". Es-tu sûr que l'"ActiveObject" est bien l'objet souhaité et de type souhaité. Concernant la perfectibilité de ta macro, effecitvement, il y a des choses à faire (ou plutôt ne pas faire). Tu utilises par ex...

Re: Trajectory in joint space with the Robot Workbench

Actually, in the general case, the inverse kinematics of robots with 6 axes have a maximum of 16 solutions, in non-singular positions. Robots of type 6R (6 revolution axes) with 3 intersecting revolute axes have a maximum of 8 solutions (this is the case of common industrial robots with a wrist). Fo...

Re: screw threads

A shell can be formed from the 4 faces (two sides of the screw + top + bottom)
Did you guys try to add a faces between the two helices with the smaller radius?

To close the shell you need 5 faces (3 sides of the screw + top + bottom), I would say.

Trajectory in joint space with the Robot Workbench

Is there a possibility to simulate a trajectory in joint space as opposed to Cartesian space with the Robot Workbench?

I can "move" the robot by giving its joints' values and then create a waypoint but this waypoint is saved as Cartesian co-ordinates of the TCP.

Re: robot Vrml file

I wrote a tutorial on how to create the appropriate vrml file from FreeCAD: https://sourceforge.net/apps/mediawiki/ ... Simulation. It should work on all models created or imported into FreeCAD.

Re: Unicode in macros

I don't think this is a problem with the editor. When I run the exactly same macro with python from a terminal I obtain what I expected. I also find it strange since, on linux, the system-wide python is used.
