Re: [Issue] Freecad Py2.5/Qt4 to Py3.6/Qt5 version update: performance issue

Hello gents,

Some news:

I tried with the following build: FreeCAD_0.19.17137_x64_LP_12.1.2_PY3QT5-WinVS2015

Everything is fast but (because?) my viewport is black...that's interesting...

Re: [Solved] Phantom paths obscure work [FIXED]

The last few messages on this topic and its relatives are amazing. Thanks guys for documenting and working the problem (which I haven't encountered) and keeping the debate cheerfully constructive. Great read, kudos!

Re: Moving beyond straight end-mills

Lookup 3d surface in the freecad wiki.

Lookup Experimental Features.

The thread i pointed to has russ's latest python scripts in the original post.

These three points of action will get you sorted!

Re: [Issue] Freecad Py2.5/Qt4 to Py3.6/Qt5 version update: performance issue

Hi triplus, thanks for joining the fray, indeed it still seems Qt5 related. Indeed it seems hardware specific. There are still Qt4 based portable bins for windows ( I used them for comparison), but I have not yet come accross the Py3.6/Qt4 combination and don't even know if that's possible. Then aga...

Re: Moving beyond straight end-mills

Hi freman, Without a picture, diagram or model it's quite hard to identify exactly what you want to do. In this blind context I'll assume I understand what you want and suggest the following answer: What you want to do is a surfacing OP. which means 3D machining (not 2.5D). A search in these here fo...

Re: CfdOF simulation for hulls

Hello, this has been partially discussed in the CfD forums specifically. It seems that DesignSPhysics is the more appropriate approach for open surface behavior (waves). https://forum.freecadweb.org/viewtopic.php?f=37&t=20595&start=40 More than this i cannot give you. But this should open the conver...

Re: 3D Surface: 4th-axis Integration and more...

Awesome answer. You make cool stuff. To be honest the journey is just as exciting as the perspectives. All i can do is bitch and moan in the most polite and constructive way possible. As another one of my running posts may end up revealing, there seems to be an interesting endeavor for optimizing ot...

Re: GCODE Export not with FreeCad19?

This matter of "exporting" vs "post processing" seems to occur often. Just to open a discussion here, is it a matter of terminology and users should "simply" learn to use the right term and therefore the right tool? Or would we benefit from some form of actual export that would export, as text, all ...

Re: In Path WB, cannot change Flat Radius and Corner Radius param

Agree with chris here on the request for a little more information. But disagree on tool handling in PathWB, when using OCL specifically and 3D Surface, it seems that Russ has already implemented the use of rounded tools. So there is one corner of PathWB that i know of where this is useful.

Re: [Issue] Freecad Py2.5/Qt4 to Py3.6/Qt5 version update: performance issue

Hello people, I am no coder, but it seems according to a very detailed answer in the following SO thread, that Qt4 to Qt5 switch should not, on its own, generate more calculation overhead for OpenGL. https://stackoverflow.com/questions/21722852/difference-in-opengl-speed-between-qt-4-5-and-opengl-ap...
