[Vertex Tools For SketchUp
Melvin Amey
With vertex tools, start with nothing selected, activate Vertex Tools and use it to select just one blue dot. You may have to turn on Ignore back faces from the right click context menu, and/or Select only Visible, depending on your model.
Hello!
I have the same problem with vertex tool. When i want to move a line or face it funcionates but when i want to select a vertices and move it it doesnt work. I checked for the soft selection and it had been 0 all the time. When I first donwloaded it I had no problem with this. I would appreciate very much if u help me solve this problem.

so , is there a toggle for the color coding on soft selection? I can edit single vertices, or grouped ones by changing the selection type but I am not seeing the color coding when I have the soft selection tool activated by typing the soft selection radius in the VBC window.

It is an online resource with various plug-ins developed made especially for SketchUp and these extensions help to add some special tools and features to SketchUp. These extensions can be found for any particular application like drawing or 3D printing and some industry specified tools for architecture, interior design, construction and many more. So basically in this Extension Warehouse people can do the following things:
Thomas Tomassen is actually known as Thom Thom, he is a modelmaker with a large desire for physical, digital and traditional design in most kinds of the trade. He is also focused on webdesign or programming and 3D visualizations but he is specialist in 3D modeling, SketchUp, Webdesign, graphic design and web programming.
This extension can take control over each vertex editor for SketchUp; its soft sections are a must needed thing for organic modeling and the manipulator gizmo will allow users to take great control while modeling. On the Vertex tolls website, users will find a list of all features along with a comprehensive manual and videos. This vertex tools can be tried for 30 days with proper registration where after the trail period, users have to buy a license to continue the use of it by paying $20.
But recently Thom Thom has updated the Vertex Tools and made a fully functional Trial version that anyone can test for 30 days. But if anyone get hooked and is a Premium Member at SketchUcation, will be enough to get lucky to have a 20% discount in the SketchUcation shop. The Trial Version of Vertex Tools is now can be found form the SketchUcation Plugin Store or the Extension Warehouse.
This pilot study aims to analyze the solar radiation transmission, daylight performance and glare reduction probability of complex shape solar control devices, developed with parametric modeling and digital fabrication. As methodology, initially the Rhinoceros3D+Grasshopper digital tools suite was used for the parametric modeling of solar control devices. Performance evaluations were performed by computational simulation and measurements in prototypes. For the simulations, the Diva-for-Rhino and Ladybug plug-ins were used. For the measurements, through digital fabrication, a prototype used for glare evaluations through HDR photographs was made. As main results, the solar control devices contributed to the control of solar radiation admission, better daylight distribution and glare reduction in the indoor analysis environment, confirming the reliability of the methodological procedures employed. It is important to highlight the effects of depth and inclination of the devices analyzed, respectively on the daylight distribution and selectivity in the admission of solar radiation between winter and summer. Finally, the shading masks show that despite all the development of modeling and simulation tools, the simple understanding of the solar geometry is still essential for the adequate performance of the solar control devices.
Este artigo apresenta uma aplicao da tcnica de contagem de pixel (PxC) em um programa de simulao energtica de edificaes para avaliar a evoluo da mancha solar nas superfcies internas de edificaes. A contagem de pixel j foi reconhecida como uma tcnica eficaz para clculos de sombreamento em superfcies externas devido a sua eficincia para simular geometrias complexas com baixo custo computacional. Dessa maneira, a tcnica foi estendida para ser aplicada em superfcies internas no software Domus. Neste artigo, uma validao comparativa da contagem de pixel implementada no Domus e um estudo do impacto da mancha solar sobre as temperaturas superficiais so apresentados. Para a validao, dois estudos de caso foram simulados e os resultados de mancha solar provenientes dos programas Domus e SHADING Tools Plugin, o qual tambm usa contagem de pixels, so comparados. Como resultado, Domus e SHADING Tools Plugin apresentam valores similares de frao solar. Usando uma zona nica como estudo de caso, o impacto da mancha solar sobre as temperaturas internas so demonstradas. Observa-se a similaridade do movimento das manchas de sol e de temperatura superficial sobre o piso, e tambm a diferena de 4 C entre as regies sombreadas e ensolaradas, o que pode impactar a preciso da simulao de conforto trmico.
Building energy models have been used since the late 1960s and are primarily used for sizing heating, ventilating and air conditioning equipment. After the oil crisis in the 1970s, greater attention was devoted to passive and innovative design strategies, which required developing a new generation of building energy simulation (BES) tools (JUDKOFF, 1988JUDKOFF, R. D. Validation of Building Energy Analysis Simulation Programs at the Solar Energy Research Institute. Energy and Buildings, v. 10, n. 3, p. 221-239, 1988.). In addition, these tools are currently being promoted around the world by green building certifications, such as LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method) because the verification of the minimum levels of thermal comfort, daylight and energy performance of buildings can be evaluated effectively through computer simulations. Thus, the success of energy-efficient design, labelling, rating and retrofit efforts depends largely on the accuracy of the analysis performed for each task (POLLY; KRUIS; ROBERTS, 2011POLLY, B.; KRUIS, N.; ROBERTS, D. Assessing and Improving the Accuracy of Energy Analysis for Residential Buildings. U.S. Department of Energy, Building America Program, 2011.). As a result, the development, evaluation and standardisation of models and software must be continually reviewed and improved to model more complex and detailed systems.
Direct solar radiation that reaches internal surfaces is one of the factors responsible for thermal gains in a building. As a consequence, a precise simulation of the conditions of direct solar incidence is essential for a good prediction of whole-building energy and thermal performance. Its evaluation requires calculating the sunlit area (Asunlit) that depends on the Suns position (provided by azimuth and altitude angles) and obstruction surface geometry (ENERGYPLUS, 2016ENERGYPLUS. EnergyPlus Engineering Reference: the reference to EnergyPlus Calculations. 2016.).
Concerning the distribution of direct solar radiation transmitted through windows, a simplified model is used in most BES tools, which assumes that all solar energy that reaches a floor is evenly distributed over it (HENSEN; LAMBERTS, 2011HENSEN, J.; LAMBERTS, R. Building Performance Simulation for Design and Operation. London: Spon Press, 2011.). For example, one of the methods used by EnergyPlus considers that all solar beam incidence is absorbed according to the solar absorptance of the floor and the portion reflected by the floor is uniformly distributed on all interior surfaces (added to the transmitted diffuse radiation). A simplified method is also used in TRNSYS, known as absorptance-weighted area distribution. From the direct solar radiation entering the window, the user must define the percentage that reaches each internal surface. In fact, as in EnergyPlus, the surface material properties and surface area are the building factors that affect the absorptance-weighted area ratios.
Although a uniform distribution of the solar heat flux on the surfaces may be sufficient for one dimensional calculation models (commonly used in most BES tools), some researchers have shown that the simplification or negligence of the sun patch distribution makes a considerable difference to the simulation results, especially for heating requirements of glazed rooms (WALL, 1997WALL, M. Distribution of Solar Radiation in Glazed Spaces and Adjacent Buildings: a comparison of simulation programs. Energy and Buildings, v. 26, n. 2, p. 129-135, 1997.; TITTELEIN, 2008TITTELEIN, P. Environnements de Simulation Adaptees Al'etude du Comportement Energetique des Batiments Basse Consommation. Savoie, 2008. PhD Thesis. Universite de Savoie, 2008.). A precise sun patch location can refine the calculation of superficial and air temperatures, as well as mapping the mean radiant temperatures for comfort index predictions (RODLER, 2014RODLER, A. Modelisation Dynamique Tridimensionnelle Avec Tache Solaire Pour la Simulation du Comportement Thermique D'un Batiment Bassec Onsommation. Lyon, 2014. PhD Thesis. Centre d'Energetiqueet de Thermique de Lyon, 2014.). Moreover, the improvement of sunlit pattern calculation as a boundary condition is fundamental for the three-dimensional (3D) heat transfer models (RODLER et al., 2013RODLER, A. et al. Are 3D Heat Transfer Formulations With Short Time Sted and Sun Patch Evolution Nececessary For Building Simulation? In: INTERNATIONAL BUILDING PERFORMANCE SIMULATION ASSOCIATION CONFERENCE, 13., Chambery, 2013. Proceedings... Chambery, 2013.). Rodler, Virgone and Roux (2016)RODLER, A.; VIRGONE, J.; ROUX, J. Impact of Sun Patch and Three-Dimensional Heat Transfer Descriptions on the Accuracy of a Building's Thermal Behavior Prediction. Building Simulation, v. 9, n. 3, p. 269-279, 2016. highlighted the contribution of a 3D thermal model to the sun patch location to evaluate highly insulated and low energy consumption buildings, which are highly sensitive to internal gains.
