"Downloading free Textures from Poliigon and using them in SketchUp/VRAY Renderings”

Textures add the realistic look in any model and Poliigon’s website is full of different textures which will increase the rendering view in SketchUp 3D models or in Vray.

Justin Geis: Justin Geis is the founder of The SketchUp Essentials and started using SketchUp while he was working as a general contractor in 2008 and after using it he found that SketchUp is extremely powerful that he just started to use it in his personal works also. Then he started The SketchUp Essentials as a place where he could share his ideas of using SketchUp easily through some tutorials and tips to help other users controlling the power of 3D Modeling in everyday lives.

In today’s article we will discuss about an online source that is contained of textures which can be used in any 3D models and renderings. There are many different websites which can also be used to download textures to use both in the SketchUp models, as well as for some programs like Vray, Unreal Engine and many more. This is a guidance to help the users in downloading and importing materials from Polligon.com into every SketchUp model, besides that there are some tips for setting the materials up within Vray for really creating more realistic renderings.

These free textures can get from www.poliigon.com , where users need to go on the top of the page to click the Sign Up button and it is absolutely free of cost website. After signing up, users can find there premium textures that can be purchased access to, as well as there are some great free textures that can be downloaded. Next they will find the texture stab, from where they have to go down to click on “Free textures” option; after clicking on this it will show a list of all the free textures available through Polligon where are list of wonderful materials to work.

Here is an example of texture-

SketchUp or Google SketchUp is mainly a3D modeling computer program that is used for a broad range of drawing applications used by architects, interior designer, landscape architects, civil and mechanical engineers, film and video game designers also. SketchUp can be getting as a freeware version named SketchUp Make and a paid version with many more extra benefits called SketchUp Pro. SketchUp is software from Trimble Company and there is an online library of free model congregations and 3D Warehouse to which users can add other models; besides that, the program has drawing layout functionality with variable ‘styles’, supports third-party ‘plug-in’ programs hosted on the Extension Warehouse to supply other abilities and enables placement of its models in Google Earth. As SketchUp users are most of architects, designers, builders, makers and engineers etc. who works hard to give a nice shape to our physical world, they need great tools to do the work. SketchUp is in mission to bring their best to produce some great tools for drawing as drawing is the key thing of the SketchUp users. They draw to search ideas, to identify the things and to show other people their work that they do with love and love to build; SketchUp understands it truly and trying to improve their software day by day. SketchUp is a worth useful software for its ease of use, it can be downloaded or installed o computer and right after that user can work on it. Though SketchUp can easily handle but still there are some sides where people will find some difficulties and lots of solve also are there like YouTube tutorials upon SketchUp or visiting SketchUp website or search Google etc. But people will get confused to have lots of information from different places upon one thing so there should a proper place or website where all the answers can be found.

Plaster 17: When users will select this texture they will get a preview window that will show the material and its look while rendering. It also shows a list of different maps that can be downloaded such as normal maps, reflections etc. They also have a pretty worthy set of free textures and one of the nice things about them is that they have different maps which users may need to link up various things like normal maps to coarsen the surface or reflection maps to make the rendered reflections look better and more. Users can select very high resolutions also but it should keep in mind that though higher resolutions look more realistic but SketchUp may face some trouble with working them. After downloading the file, users can unzip it and place the materials in their file; next it need to bring into Vray by opening up the Asset Editor, then go to the Material List and click the “Add Material” button at the bottom of the page and select “Generic”. From here, users can add the maps into Vray material, clicking on the right arrow button will help to expand the window off to the right where they can add texture to this material by selecting the little box next to “Diffuse” and finding the color map. This option will add the texture image to the material and going in the material section, the size of the material can adjust; also adding different maps from the material it become more realistic.

"Design parts in SketchUp to connect for 3D printing”

SketchUp models are suitable for 3D printing but it only can happen when the parts of any model are assembled together, there are different ways to assemble those parts.

In the previous tutorials of Sketch Up, Aidan and Rebecca have shown us the way to cut Sketch Up model into parts but the matter is now to assemble them in a way for printing them. There are many other strategies and features in SketchUp like mechanical or else to help in building into the model to assemble the parts together. Aidan and Rebecca are going to show the users through different processes and here is a brief discussion on it.

Tolerance in SketchUp: It is the difference between the sizes of users’ part in SketchUp and the size of the part produced by their 3D printer. Suppose a user has drawn a 10mm cube in SketchUp and printed it, none of the sizes of the printed cube will be shown exactly 10mm; though these are very small differences like a few tenths of a millimeter more r less. But they can create problems if their 3D printed parts have to connect with the parts that already exist in the real world. That’s why the manufacturer of the 3D printers gives a unique number for the machine’s tolerance which may be in either plus or minus value. This value is called the Maximum variation for that machine and users both need to be aware while working.

Tolerance in SketchUp: Clearance is like an extra space for parts to slide past one another but users may face a little difficulty while installing similar size peg in a similar sized hole as they will not go together. The peg and the hole will not fit properly with each other in SketchUp but in real world they will not react like this as there the peg needs to connect with friction. The exterior of the peg is similar as the exterior of the hole that the friction between them will keep the peg from veer going in if the fit is too perfect for them. In that case, users need to add a small amount of space called clearance which will help the two parts to slide past each other; the amount of clearance depends on the exact movement of the part.

Glue in SketchUp: Glue is the universal way to stick things but it is also the weakest and most unreliable way as it has very little strength o keep the things tighter for long.

• The plastics which are used in 3D prints defined by the names ABS, PLA, PVA, nylon and PETT; all these plastics need a special glue to stick and the glues have to order online.
• Biodegradable starch plastics consists a crystalline structure that doesn’t go well with liquid superglue which stays liquid and move unexpectedly across the surface of the part.
• Instead of glue, users can use epoxy which is though a messy stuff but will stick to anything.
• No glue can stick to the flexible materials for 3D printers so to attach parts, a process called thermal welding.

Snap fittings in SketchUp: These are properly designed to pop the models together after the parts come off the printer and as these are removable so users can change out many parts of the model as per design. In SketchUp, snap fittings are created by two general steps: 1) creating the tongue with the Line and Push/Pull tools; 2) creating a matching capture point on the opposing part.

Press Fit in SketchUp: A press fit is the very little clearance between the two parts while designing and when the parts are pressed together forcibly, friction keeps the joint together without any extra hardware or glue. To make a press fit, the Offset tool is used to create an outer lip on one side of the connection and an inner lip on other side.

Bolts, Screws and Hardware in SketchUp: The strongest connection between 3D printed parts is holding together with metal hardware and these connections are great for things that are more than just prototypes. While integrating hardware into the design, include hardware in the SketchUp model as it will take measurements of the parts users need to use and model them in SketchUp. Then save the components in the component library for using them in further models.
