Thingiverse is a website dedicated to the sharing of user-created digital design files. Providing primarily free, open-source hardware designs licensed under the GNU General Public License or Creative Commons licenses , the site allows contributors to select a user license type for the designs that they share.
Some of them like Thingiverse are dedicated to free sharing of 3D printable files. Others, like Shapeways offer a 3D printing service for objects which have been provided for sale by designers. MyMiniFactory offers a combination of these two: their main activity being the free sharing or 3D printable files, they also offer print-on-demand and ...
First solution that combines unconstrained space geodesy solutions free from any tectonic plate motion model. [4] From this version onwards, the motion of the tectonic plate is represented in the solution for each station as a velocity vector. Previous ITRFs only continued the initial positions, using a motion model to fill in the velocity ...
Trimble Inc. is an American software, hardware, and services technology company. Trimble also does hardware development of global navigation satellite system (GNSS) receivers, scanners, total stations , laser rangefinders , unmanned aerial vehicles (UAVs), inertial navigation systems and software processing tools.
SketchUp is a 3D modeling software that is used to create and manipulate 3D models. It is used in architecture and interior design.. SketchUp is owned by Trimble Inc. The software has a free web-based version, and three paid subscriptions to gain access to applications for Windows and macOS.
GeographicLib provides a utility GeoidEval (with source code) to evaluate the geoid height for the EGM84, EGM96, and EGM2008 Earth gravity models. Here is an online version of GeoidEval . The Tracker Component Library from the United States Naval Research Laboratory is a free Matlab library with a number of gravitational synthesis routines.
The geometrical separation between it and the reference ellipsoid is called the geoidal undulation, or more usually the geoid-ellipsoid separation, N. It varies globally between ±110 m. A reference ellipsoid, customarily chosen to be the same size (volume) as the geoid, is described by its semi-major axis (equatorial radius) a and flattening f.
The software is used in engineering for creating output such as calculations, sketches and notes. [14] Tekla BIMsight is a software application for building information model-based construction project collaboration. It can import models from other BIM applications using the Industry Foundation Classes (IFC) format, also DWG and DGN. With Tekla ...
