Data Interoperability with FME workbench

'Rather than hand modelling the 2 million buildings, HOK used FME Desktop to automatically generate the 3D buildings from existing data without writing any code. Using FME, they transformed and integrated BIM, GIS, CAD, and raster data, extracted subsets of data, added attribute information, and carried out calculations along the way.' to find out more...

Blender for Architecture by Prof Ludger Hovestadt


We have a full series of them! Open source! I can't sleep seeing all this...
Learn! Now!
  • Download from https://www.blender.org/2-8/
  • Unzip it into your folder that will take a few minutes and you can rewatch the video.
  • To launch the program, look for the blender icon which is the Application (.exe) file, double click it.
  • Technically, the 1st step in learning any modelling tool or software is - Navigation:https://www.youtube.com/watch?v=IWLR-WDJdCs

Anaconda-Python Setup Records




If you encounter problems below:
  • twisted 18.7.0 requires PyHamcrest>=1.9.0, which is not installed.
just install below:
  • python.exe -m pip install PyHamcrest
If you encounter problems below:
  • Command "python setup.py egg_info" failed with error code 1 in C:\Users\yourfolder\AppData\Local\Temp\pip-install-8s57p4nw\fiona\
just install below:
  • python.exe -m pip install -I https://github.com/pypa/pip/archive/master.zip#egg=pip
  • python.exe -m pip install --upgrade setuptools
  • python.exe -m pip install ez_setup
  • python -m pip install --upgrade pip
  • python -m pip install psycopg2
  • pip install -I https://github.com/pypa/pip/archive/master.zip#egg=pip
  • pip install --upgrade google-cloud-datastore (this will prompt the PATH issue)
Still doesn't work? Try follow this (if you have install Microsoft visual studio 2017):

GeoPandas, Shapely, Fiona, PySAL, Pyliburo & Py4design

'GeoPandas is an open source project to make working with geospatial data in python easier. GeoPandas extends the datatypes used by pandas to allow spatial operations on geometric types. Geometric operations are performed by shapely. Geopandas further depends on fiona for file access and descartes and matplotlib for plotting.' to find out more...

'Shapely is a Python package for set-theoretic analysis and manipulation of planar features using (via Python’s ctypes module) functions from the well known and widely deployed GEOS library. GEOS, a port of the Java Topology Suite (JTS), is the geometry engine of the PostGIS spatial extension for the PostgreSQL RDBMS. The designs of JTS and GEOS are largely guided by the Open Geospatial Consortium’s Simple Features Access Specification [1] and Shapely adheres mainly to the same set of standard classes and operations. Shapely is thereby deeply rooted in the conventions of the geographic information systems (GIS) world, but aspires to be equally useful to programmers working on non-conventional problems.' to find out more...

'Fiona is designed to be simple and dependable. It focuses on reading and writing data in standard Python IO style and relies upon familiar Python types and protocols such as files, dictionaries, mappings, and iterators instead of classes specific to OGR. Fiona can read and write real-world data using multi-layered GIS formats and zipped virtual file systems and integrates readily with other Python GIS packages such as pyproj, Rtree, and Shapely. Fiona is supported only on CPython versions 2.7 and 3.4+.' to find out more...

'Urban design optimisation is a powerful method for the exploration of multiple designs. In performing an urban design optimisation, we need to link and automatically execute multiple domain-specific applications, a technically complicated setup. Current solutions resolve the technical obstacle by embedding the applications within a single Computer-Aided Design (CAD) application to streamline the setup. The solution leverages the CAD application’s modelling workflow and capability to process the urban geometries for analyses. However, this solution is workflow specific; users either do not have access to optimisation algorithms or are restricted to the capabilities provided by a specific CAD application. For optimisation to be accessible to a wider community, we develop an open Python library, Pyliburo, to provide optimisation capability to all design workflows. Pyliburo aims to be easily integrated into a user’s existing design workflow to provide or enhance optimisation capability. To do so, Pyliburo emphasises interoperability, platform independence, ease of use, integration flexibility and extensibility. to find out more...

Generative Design

'Generative design is a form finding process that can mimic nature's evolutionary approach to design. It can start with design goals and then explore innumerable possible permutations of a solution to find the best option. By using cloud computing, generative design can cycle through thousands or even millions of design choices, test configurations and learn from each iteration what works and what doesn't. The process can enable designers to generate brand new options, beyond what a human alone could create, to arrive at a most effective design.' to find out more...
