IfcOpenShell packages available in Community Extras PPA

[kkremitzki]

Howdy,

An experimental IfcOpenShell package is now available in the Community Extras PPA for Ubuntu 16.04/18.04. Please test it out and report any issues here so this package can be integrated into Debian and future versions of Ubuntu.

Python 3.

based on Python2 or Python3?

I updated the package to build Python 2 only instead, and as a result it now builds on Ubuntu 14.04 as well.

Have a persistent problem with importing ifc

Enclosed pls find exported from fc a simple wall. When importing, this or any other ifc file FC hangs. Believe Paullee experiences the same.
My hunch is this has something to do with UTF8 character encoding or maybe some locale settings. Experienced the same on all ubuntu setups.
Works on Win.

Can you try going to the folder you have wall01.ifc at, opening a Python interpreter and doing:

Code: Select all

import ifcopenshell
f = ifcopenshell.open("wall01.ifc")

?

There is some bug in Arch (the Normal property of that wall doesn't work correctly), I'll try to find out what's wrong, but the problem is most certainly not in ifcopenshell...

Believe this is definitely an encoding issue..

I've installed IfcOpenShell via the Community Extras PPA on my Ubuntu 18.04, but FreeCAD (v.0.18.1) can't find it so IFC import and export are not working at all. I've installed FreeCAD with freecad-python3 dependency, not freecad-python2.

If it can be useful these are the commands I launched by terminal:

Code: Select all

sudo add-apt-repository ppa:freecad-community/ppa
sudo apt update
sudo apt install ifcopenshell0

Thanks for your help
