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

I wonder if it would be interesting to draw up a possible BIM workbench. I have no programming knowledge to develop it, and most likely, you are already thinking about it, but in any case I would like to (re)introduce the subject. Mounting a BIM file is very similar a assemble a object and I noticed that the Assembly2 workbench (and others) already have much of what could be use in a BIM with some minor modifications. For example (figure): insertion of complete files (not only parts, linked and upgradeable), basic changes tools (move, rotate, scale), interference checking , preparation of compatibility reports, lists of linked files and their locations, dimensions checking (lengths, volumes, etc. ), quantities spreadsheets, etc...

Gracias por tu contestación. Esto me permite aclarar una mera sugestión o punto de vista. El Arch workbench es excelente, sin duda (¡vengo lo utilizando muchísimo!). Luego, no se trata de ignorar el gran trabajo que se viene haciendo. Sin embargo, como criterio meramente conceptual creo que sería provechoso diferenciar la fase de elaboración de la de montaje (assembly), al igual que para el mundo del objeto ya existen en FreeCAD los workbenchs para construcción de los elementos principales y simples (Part, Part Design y Draft) y para montaje final de los objetos, el Assembly workbench.
 
En este sentido, imaginemos el marco en que tenemos que importar (o mismo elaborar en Arch workbench) archivos 2D y 3D de los diferentes temas de la construcción (arquitectura, estructura, fundaciones, instalaciones, aire acondicionado, etc.) y necesitamos manejar estas informaciones en un único archivo con un workbench específico para construcciones (el BIM workbench).
 
El montaje de archivos BIM es un tema en que vengo me involucrando y trabajando. Veo que FreeCAD tiene una gran ventaja por ser libre, abierto, modular, adaptable y flexible, teniendo un gran potencial de volverse en una plataforma única en el futuro, utilizado en casi todas las asignaturas, y, distintamente de lo que existe, sin los altos costes impeditivos involucrados.

anyone know how to slice a model temporarily so I can work on some of the inside without the other parts coming in the way. I can use Clipping planes to just "view" part of an object, but I want it to be persistent.

Just curious does freecad have any facility to add detail to a surface from perhaps an image like height map style ? i

if not a height map are there other options for adding detail for engraving other than modelling it from scratch ?

Slightly off-topic, but why is it that there's no open-source CAM for programming lathes? I think I've only seen 3-axis milling, like the new Path workbench in FreeCAD. I guess it's easier to deal with XYZ and not having to do away with one axis? ☺

I understand. I was just curious as why I haven't seen it implemented anywhere (not in any library either). Will be interesting to see how it will be implemented in FreeCAD :)

Writing text is faster than coding.  miki - - an idea to simplifiy coding
describe different structures (qt, freecad, open inventor) with the same language

I was searching about CAD kernel at : https://en.wikipedia.org/wiki/Geometric_modeling_kernel mainly because of opencascade seems to be the freecad bottleneck...

what do you think about ACIS ? Someone ever tried to look at another option (if exists) than OCS ?

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).

If there is one thing I'd like Freecad on windows to do that it does on Linux, it has to be the the icons that shows a preview of the design.

So I'm reading through the new manual, that +Normand Chamberland posted about below, I get to the part on installing and after that I hit the 'next page' button and it takes me back to the 'Installing on Windows' part of the page. Frustrating on the phone cause I don't have the navigation column on the left like I do when on the laptop.
Just a heads-up.

As I work on the geodata workbench  this nice to read book is free for today at

So anyone can see what is behind OSM and what data can be reused
Imagine being able to create accurate maps that look how you want them to, and use them on the Web or in print, for free. OpenStreetMap allows exactly that, with no restrictio...

Speech synth freecad tutorials

Maybe I'm aiming too high, but it would be nice to have a tag-searchable web of FreeCAD tutorials that start a new project and walk you through a FreeCAD feature with voice accompaniment, explaining what the tutor was doing.
It would begin with a short "fly-by" with a voice-over describing the finished product, so (user) browsers could more easily filter on what they were searching for.
Missing (to new/not-new users) entries could be smart-tagged, those tags liked by other users and the developers could see what their users most wanted or even where the direction of development could change #tag #net #learn #tutorial #voice-over #animation #fly-by

Wow
Have you noticied that the count of the google community has nearly doubled  during the last year. More visitors and users, more ideas and more helping hands. Nice to see how FreeCAD grows and improves every day. It's nice to be part of this community with its free and good quality support.

A proposal has been made to create a Stack Exchange site for FreeCAD questions, we need followers and questions in order to get this live.

If anyone has any doubts, the purpose of the Stack Exchange site is to allow the interaction of users in a Q&A manner, perhaps some of you might have found it hard to get the correct answer for a specific problem while using FreeCAD so this is an opportunity to reduce the gap between inexperienced and senior FreeCAD users. 

Please note that this will not replace the forum in any way. Considering how FreeCAD users have begun to use different sites for information (including the +FreeCAD community), this is another option some of you may find more adequate.

Excellent. StackExchange would be great for Q&A for FreeCAD !! Stack Exchange gamifies Q&A. Experts compete to give the best answer to a well formulated question. FreeCAD has a very bright future, and as the job market for FreeCAD experts/programmers grows, SE will be part of a healthy ecosystem for FreeCAD.
