FreeCAD | official source code of FreeCAD , a free and opensource | Development Tools library

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)*

This works:

FreeCAD.ActiveDocument.myBox.Length = 150

This doesn't:

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.

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:

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.

System Info:

• macOS Big Sur version 11.5.1
• Homebrew version 3.2.5-15-g13d3eab
• FreeCAD Version from latest master, see https://github.com/FreeCAD/FreeCAD

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:

https://wiki.freecadweb.org/Embedding_FreeCAD

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:

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().

The following code is a slideshow page with 5 slideshows using Owl Slideshow Platform. Each of these slideshows show five pictures each at a time. 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.

I'm trying to run Firefox in a Debian docker image but can't connect to the X11 server.

I'm using the method described here, but changed the base image to the latest Debian. I also changed the user creation method.

Dockerfile

I am trying to build a (node.js + python) image. This is the dockerfile i used:

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[0][0][2] is a Vector whose x coordinate happens to equal the value of the width parameter in spreadsheet cell A5.

If one invokes the script as
