FreeCAD 0.16 / 0.17 AppImage builds

probono, an AppImage developer, has been helping the FreeCAD people to create AppImage bundles of FreeCAD. AppImages should be able to run on most recent Linux distributions.

AppImages are super easy to use: once downloaded, right-click on it to get its properties, and set it to be run as an executable. Then simply double-click it to launch!

For now the AppImage builds are hosted by probono, but they may eventually be hosted on FreeCAD's Github.

https://bintray.com/probono/AppImages/FreeCAD

Click on the wanted version, then on "Files".

If you have problems, please report them over the FreeCAD forum: http://forum.freecadweb.org/viewtopic.php?f=10&t=15525

+Marcus Wolschon AppImages don't contain _all_ libraries, only those that cannot reasonably be expected to be part of each target system. For system libraries like glibc, it uses what comes with the system. In this regard, it is exactly like what you do if you distribute a Qt application to Windows or macOS.

Just a cautionary tale with major upgrades and backwards compatibility...
 
Hi! I just posted a new post on Pepper&Carrot blog: "New Inkscape 0.92 breaks your previous works done with Inkscape" (Link: http://www.peppercarrot.com/en/article396/new-inkscape-0-92-breaks-your-previous-works-done-with-inkscape ). #inkscape #floss

Apologies, +Normand Chamberland​ as it was a g+ post, I just hit share within the same network. First post in freecad community so still figuring out who is where.

Sorry it took 3 days to approve your post, apparently I'm the only one who moderates this community. I deleted the second post you made (no doubt because the first one was not visible).

It would be great if you filmed the Modeling with FreeCAD presentation and published it, even if I can't understand Italian. :-D

Hello. Say I want to design a carriage system. Is it possible to simulate such system and see if it works in Freecad? If not can you suggest me a program for that?
Thanks in advance.

3D printable board, with a button for using with the FPGA Icezum Board. It has been designed in Freecad 0.16. All the electronic components have been uploaded into the Freecad Parts Library

For a medium sizes mesh FreeCAD has been calculating for 7+ hours now.
Any idea what my mistake could be?
To implement an algorithm I need a map of each mesh Point to the list of mesh Points with larger x coordinates that it's connected to via a Facet (there are no Edges).

import Mesh
mesh = Mesh.Mesh("test.stl")

nextPoints = {}
leftmost = mesh.Points[0]

for face in mesh.Facets :
for currentPointIndex in face.PointIndices :
currentPoint = mesh.Points[currentPointIndex]
if (currentPoint.x < leftmost.x) :
leftmost = currentPoint

for face in mesh.Facets :
for currentPointIndex in face.PointIndices :
currentPoint = mesh.Points[currentPointIndex]
for otherPointIndex in face.PointIndices :
otherPoint = mesh.Points[otherPointIndex]
if otherPoint.x > currentPoint.x :
next = nextPoints.get(currentPointIndex, [])
next.append(otherPoint)
nextPoints[currentPointIndex] = next

No, I use FreeCAD and it's python scripting.
After all, this is the FreeCAD Google+ Community. These meshes are HUGE. They should never, ever be copied. Having to create that giant nextPoints hashtable because FreeCAD doesn't allow me to get the edges/faces/loops for a given vertex is already an ugly workaround.

If anyone tries any python on Meshes in FreeCAD:
Beware! mesh.Points are of type MeshPoint.
face.Points are NOT. They are tuples.
And these tuples are even missing their index.
So iterating through the points of a face (in the absende of any concept of an EDGE) is pointless because you'll never get the identifying index for your point anymore.

I fixed the online documentation of the Mesh API to reflect this (and other pitfalls).

I had a look at the Robot Workbench documentation.
There is no way to import g-code as a trajectory, is there?
I'd really like to simulate g-code for 4, 5 and 6 axis milling I create to debug my tool path generator.

With Version 3.3.2 V-Rep (http://www.coppeliarobotics.com/downloads.html) got support for G-Code.
Pro Edu Version is free for personal/academic use.
Maybe that would be an option ?
