Re: 4 cylinder steam engine

Nice one! What is the reason to have the 180° differential of the pistons, and not 90°? As it is now you have a dead point where no force can be created (the situation shown in the pictures), but with each piston rotated by 90° you could have continuous force, which allows a smaller flying wheel.

Re: App::Link: the big merge

Congratulations for the merge, a lot of work was put in with remarkable endurance, well done! There is not many code that is dedicated to LinkGroup, it's just that App::Link must be group aware (it has special handling when linked to plain group and geo group), and act like group in some situation (...

Re: App::Link: the big merge

While playing with the branch I did not really understand the purpose of the LinkGroup. Could you explain what the benefit of this object is compared to a simple combination of App::Part+App::Link and what use cases you support with that?

Re: Reversed Sweep doesn't work?

No, actually those two properties do not make any sense for the sweep and loft tools. They come from the implementation, as both are based on the "SketchBased" class which brings those properties. But they are not really used. That should be changed somehow.

Re: How to distribute CPU intensive operations?

It depends on the solver implementations, but some support it over MP, e.g. elmer and fenics. Especially elmer should work in freecad pretty well. So you should carefully choose the right solver and than try to use their capabilities.

Re: Set mouse cursor position

Mouse cursor is controlled by Qt, so you can use it to change the position: from PySide.QtGui import QCursor QCursor.setPos(10,10) This does use screen coordinates, not widget coordinates. But you can easily translate between the two by getting the widget screen positions and do some simple calculat...

Re: Alternative GUI for FreeCAD: Overlayed Layout (Devs needed)

A few thougth from my side: - Like ickby, I will want to replace MDI's center widget with my own Thats the way to go, to redefine the MDIView so it can handle the QML stuff. However, IMHO you don't want to replace FreeCADs MDIView implementation, but change it. The reason for this is the deep integr...

Re: FEM output does not seem to be correct (beginner question)

what you see is correct. The options show what data of the result is used to color the part. "Abs displacement" means it uses the displacement vector, the absolute value of it. Hence sqrt(dx^2+dy^2+dz^2) where dx and dy is the displacement in x and y direction. So you see no color at the bottom trus...

Re: Alternative GUI for FreeCAD: Overlayed Layout (Devs needed)

And, hopefully, the FreeCad API will help me talking to the non-qtquick sections of the application through a QObject-API. Like QWidget, QtQuick is based on QObject and does everything through signals and slots, so all should be well. It depends on how you want to interact with the system. My appro...

Re: Datum objects in App::Part

what do you say about making this move?
I'm not going to do that, sorry, but I don't have time for freecad programming anymore. Also it is not soo hard to do, someone else can easily pick this up :)
