kandi X-RAY | FreeCAD Summary
Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters. Create 3D from 2D and back FreeCAD lets you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings. Designed for your needs FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture, whether you are a hobbyist, programmer, experienced CAD user, student or teacher. Cross platform FreeCAD runs on Windows, macOS and Linux operating systems.

I am a student and recently got mac M1, we are being taught FreeCAD(first opensource software ever), but the problem is the build is availble for intel Mac's and I am facing issues.
But on deep search through forums I found the build of this guy. Can somebody help me out on what he wants to convey. FreeCAD forum thread screenshot...

the person is telling you that the result gives the platform. You can try this:
I'm quite new to Python so the answer to my question might be simple or impossible.
In below shown example I would like to substitute the object name "myBox" with a variable boxName.
boxName = "myBox" FreeCAD.ActiveDocument.addObject("Part::Box", boxName)*
FreeCAD.ActiveDocument.myBox.Length = 150
FreeCAD.ActiveDocument. + boxName + .Length = 150
I get a syntax error:
'App.Document' object has no attribute 'boxName' or when I try other variations I get this error: (1): ('invalid syntax', ('###/AppData/Roaming/FreeCAD/Macro/nyMacro.FCMacro', 5, 24, 'FreeCAD.ActiveDocument.+(boxName)+.Length = 150\n'))
If it's possible to substitute with a variable, I will be gratefull if someone will show me the syntax....

You have to use meta programming. Do a little study about this concept. It's interesting. In Python you can execute dynamic code by eval function:
eval('FreeCAD.ActiveDocument. + boxName + .Length = 150')
Do seaech about eval and exec function if I'm not wrong.
I'm looking to compile OCCT 7.5 in Windows 10 (x64 via VS2019) for use with FreeCAD, to enable exporting glTF files, which requires RapidJSON support (in OCCT). I've checked out OCCT 7.5.3 and RapidJSON 1.1.0 from their git repos, then grabbed the FreeCAD libpack 12.5.2 (for OCCT 7.5). I started from FreeCAD's build docs, then attempted to follow OCCT's build docs.
When configuring the OCCT project in CMake-GUI, I've been able to find what I think are correct values for some variables (e.g. those regarding FREETYPE) within the FreeCAD libpack, as well as RapidJSON, but still get some errors in the config, seemingly no matter what values I try:...

The problem was my lack of familiarity with CMake and Cmake-gui: the gui opened a dialog for a FILEPATH when specifying a PATH variable. I naively thought, "I don't know CMake, so I'll trust the gui". Totally wrong.
I manually edited the 3RDPARTY_* variable entries to point to the correct directories (or libs, when needed) in the FreeCAD libpack, using the variable name and description/hint for each to determine what the variable's value should be. Below are my entries, for reference: I did need to check "Advanced", to edit the FREETYPE_LIBRARY_DEBUG & FREETYPE_LIBRARY_RELEASE variables (CMake set them to separate libs found in a jdk directory, presumably because it was added to the system path at some point).
I’m stuck compiling FC on macOS Big Sur. The build breaks with an error not finding certain XercesC libraries. But these libraries are installed and the path is even found by the CMake preparation process.
I postet this issue in the FreeCAD forum under https://forum.freecadweb.org/viewtopic.php?f=4&t=60663, but found no help. I would appreciate if anyone here at StackOverflow could verify this error or better yet have a hint for a solution. Thanks in advance.

How do I setup a Python virtual environment with the FreeCAD library embedded as to enable import as a module into scripts?
I would like to avoid using the FreeCAD GUI as well as being dependent on having FreeCAD installed on the system, when working with Python scripts that use FreeCAD libraries to create and modify 3D geometry. I hope a Python virtual environment can make that possible.
I am working in PyCharm 2021.1.1 with Python 3.8 in virtualenv on Debian 10.
I started out with FreeCAD documentation for embedding in scripts as a basis:
In one attempt, I downloaded and unpacked .deb packages from Debian, taking care to get the correct versions required by each dependency. In another attempt, I copied the contents of a FreeCAD flatpak install, as it should contain all the libraries that FreeCAD depends on.
After placing the libraries to be imported in the virtual maching folder, I have pointed to them with sys.path.append() as well as PyCharm's Project Structure tool in various attempts. In both cases the virtual environment detects where FreeCAD.so is located, but fails to find any of its dependencies, even when located in the same folder. When importing these dependencies explicitly, each of them have the same issue. This leads to a dead end when an import fails because it does not define a module export function according to Python:...

This is what I did to get FreeCAD to work with PyCharm and virtualenv:

Given a FreeCAD model that consists of
- Spreadsheet "parameters" with a cell aliased as "radius" and value 50
- Icosahedron (from the Pyramids-and-Polyhedrons macro) with Radius=parameters.radius
- some facebinders which are unimportant for the purpose of this question,
the python script below opens this model, changes the radius cell in the Spreadsheet to 15, call recompute() on the spreadsheet, invokes touch() on the icosahedron, calls recompute() on the document, and finally tessellates the icosahedron. The z coordinate of the vertex at index 11 in the tessellated mesh happens to be equal to the icosahedron's radius. I was expecting it to change to 15, according to the parameter change. But it remains at its original value 50. What am I doing wrong?
To my understanding the macro's execute method should get invoked during the recomputation of the document.
When I trace Document.recompute() with pudb, I only see it executing Facebinder.execute() but not Icosahedron.execute(). The path it takes from Document.recompute() to Facebinder.execute() method is not visible in pudb; it immediately stops in Facebinder.execute()....
ANSWERAnswered 2021-Mar-12 at 23:58
I figured it out. The reason was
Pyramids-and-Polyhedrons not being imported after all.
The first problem was that
FreeCADGui (in order to install its workbench), which depends on certain native libs that need to be added to
LD_LIBRARY_PATH before running the script:

I need six photos on one slideshow shown at one time instead of five. I have tried experimenting with the . I tried commenting and seeing what would happen if I changed values, however, no luck. My question is how do a make one of the slideshows show six pictures at a time instead of five? Thank you....

You can try by adding the
items option when initializing the carousel. I've tested it on CodePen, and it seems to work. I've tried with different numbers.

Let's say I have a FreeCAD model that defines a certain geometry with dimensions height, width, and length that are defined in cells of the model's spreadsheet. I want to build an automation pipeline in a stand-alone Python script using the FreeCAD module that - reads that model - sets the spreadsheet cells to values provided by the client - recomputes the model accordingly - generates geometry by tessellating the model's parts for further processing outside of FreeCAD (irrelevant with regard to this question)
The script is working except that it fails to change the parameter values that are used to compute the model. The resulting geometry always reflects the original values that were saved with the model.
I've added an assert command (line 44).
geometry is a Vector whose
x coordinate happens to equal the value of the
width parameter in spreadsheet cell A5.
