FreeCAD#

Working with 2D CAD applications like QCAD and LibreCAD was a fun, but I want nice 3D renderings, so let’s give Freecad a go.

My main use case is planning the furniture layout for our house. I have a basic floor plan and did some measurements that I want to translate into a 3D model.

Getting started#

FreeCAD 2025 BIM - Architecture - Complete Beginner Tutorial - YouTube

To change the navigation style to Blender after the fact: Right-click an empty area in the 3D view > Navigation styles > Blender.

Mouse Rotation Style#

This drove me mad.

> Settings > Orbit style: Turntable

Sketcher: hide units#

Edit > Preferences > Sketcher > Display > Hide base length units for supported unit systems

Später am Abend komme ich nur noch dazu, Videos zu schauen, ohne Notizen zu machen. Hier ist die Liste der Videos von gestern:

BIM Library#

https://wiki.freecad.org/BIM_Library/en

You must install the Parts Library https://wiki.freecad.org/Parts_Library_Workbench.

Installation died with

Failed to install parts_library
Git returned a non-zero exit status: -1
Called with: /app/bin/git clone --recurse-submodules https://github.com/FreeCAD/FreeCAD-library /home/felix/.var/app/org.freecad.FreeCAD/data/FreeCAD/Mod/parts_library

Returned stderr:
Cloning into '/home/felix/.var/app/org.freecad.FreeCAD/data/FreeCAD/Mod/parts_library`

Workaround

git clone --recurse-submodules https://github.com/FreeCAD/FreeCAD-library /home/felix/.var/app/org.freecad.FreeCAD/data/FreeCAD/Mod/parts_library

There still was no “BIM Library” button as shown in the wiki, but the following (from the library’s README) worked: Macro > Macros: PartsLibrary.FCMacro

To search the library:

fd . --type file ~/.var/app/org.freecad.FreeCAD/data/FreeCAD/Mod/parts_library | sort | fzf --layout reverse-list

Trivia#

Tiefe und Breite im Baurecht#

https://de.wikipedia.org/wiki/Grundstückstiefe

  • Tiefe: von der Straße weg; meist Nord/Süd

  • Breite: orthogonal dazu

Deswegen habe ich für die Terrasse zwei Dimensionen, die ich wie folgt benenne:

  • terrasse T

  • terrasse B

Bei mir sind die Namen Lowercase, auf die er weiß ich, dass sie von mir kommen. Sowas macht ja sonst keiner.
