Export volume, mass, weight and volume centroids from Rhino to .csv file

An interesting topic emerged at Mcneel forums: calculating Rhino solid’s volume, mass, weight and centroids. Then exporting that data into .csv file.
The following modest rhinoscript function tackles this issue. Check it at github.

Depending on Rhino unit system, data will be exported with following units:

units: Millimeters:    length(mm), volume(mm3), mass(g), weight(N – Newtons)
units: Centimeters:    length(cm), volume(cm3), mass(g), weight(N)
units: Meters:    length(m), volume(m3), mass(kg), weight(N)
units: Inches:    length(in), volume(in3), mass(oz – ounce), weight(N)
units: Feets:    length(ft), volume(ft3), mass(lb), weight(N)

Function additionally labels object’s number’s and volume centroid points are added to the Rhino file:

Water supply design definition


I created a Grasshopper definition which designs cold water supply branched network, by using Joseph Brix methode.
Unit load according to German standard DIN1988-W308.
Definition uses an evolutionary algorithm – Octopus to determine the most efficient solution in terms of energy losses along the network.

Grasshopper to RFEM/RSTAB

I made an example of exporting data from Rhino/Grasshopper into Dlubal’s RFEM, by using Excel spreadsheets.
The same method can be used for RSTAB.
RFEM/RSTAB are structural analysis and design softwares:

Video show changes in geometry of grid shell and space frame in Grasshopper, which are then reflected to the geometry in RFEM/RSTAB ready for analysis:

Sierpinski pyramids

This project represents my experiment to create Sierpinski square-based pyramids as fractals and also an example of feedback loops usage within Grasshopper.

Code allows manipulation of size of pyramids and the number of iterations within (number of pyramid sub levels). Each one of these three has a different sub level.

Parametric interior – salon for reading

Area 160 m2

Location: Plav, Montenegro


My ex company gave me an opportunity to be involved in design of interior, for 4 star hotel  located at Lake of Plav, Montenegro. Hotel is going to be build near lake, surrounded by fairy tale scenery and beautiful mountains.

Their task was to design interiors for restaurant, banquet (function) hall lobbies and salons.
My job was to design the reading part of salon located on the south side of hotel.

Reisseck mountain restaurant and visiting center – international competition 2011 (1st prize)

Area: 1180 m2

Location: Reisseck, Austria

Project status: Under construction

This project won the 1st prize on the international competition in 2011. Snøhetta was third.

Object will be built 2250 meters above sea level in Austrian Alps.  The building will include a top terminal for the Reisseck incline railway, along with information and display areas.

The new top terminal has been interpreted as constructed landscape, which has developed naturally from the topography. The curving lower part of the station follows the contours of the surrounding landscape, and these are accentuated by their stone materiality. The roof encroaches on the building like a protective overhang of snow. Despite avoiding the vernacular architecture of alpine construction, this solution has produced a sensitive response to this unique location.
On the approach, the visitor is heralded by a sequence of different rooms. The ground floor, which is integrated into the slope and is closed to the outside world, is reminiscent of caves and tunnels.
