Unit 10-Rendering & Sharing Your Work DT2510: Advanced CAD Methods Using the Material Browser You can access the vast Autodesk library of real world materials Materials are organized in a tree that you can easily navigate to locate the type of material you are looking for Single-click a material to load it into the current drawing Double-click a material to open it in the Material Editor for customization Unit 10-Rendering & Sharing Your Work Assigning Materials by Layer Expand the Materials panel and select the Attach By Layer tool, or Use the MATERIALATTACH command In the Material Attachment Options dialog box drag materials youve already loaded into the drawing using the Material Browser onto specific layers in the right half of the dialog box. Click a red X if you make mistake and the material is cleared Unit 10-Rendering & Sharing Your Work Photometric Lighting AutoCAD features two separate lighting systems: standard and photometric Standard lighting is a legacy system that isnt based on real world optics Photometric lights are enabled when you select either American or International lighting units Expand the Lights panel on the ribbons Render tab to select lighting units Photometric light is attenuated with the square of distance just like light behaves in the real world Unit 10-Rendering & Sharing Your Work Placing Lights Spot lights have both a lamp position and target position You can specify 3D coordinates in the top view using point filters In the top view, type.xy to specify both X and Y coordinates by clicking in the drawing canvas You will be prompted to specify the Z coordinate on the keyboard Unit 10-Rendering & Sharing Your Work Specifying Geographic Coordinates You can specify geographic coordinates using the Location Picker dialog box if the coordinates of the nearest big city is a close enough approximation You also have the option of using Google Earth (free or Pro) to pinpoint the exact latitude and longitude of your particular site Geographic coordinates help determine the precise sun angle of a real world site Unit 10-Rendering & Sharing Your Work Adjusting Exposure It is necessary to adjust the exposure in most photometric lighting simulations Adjusting exposure is not a cheat the lighting remains an accurate physical simulation Adjusting exposure is means of tone mapping, or adjusting the wide dynamic range of the lighting simulation to the narrow range displayable on a computer monitor You should always adjust the exposure prior to performing test renders Unit 10-Rendering & Sharing Your Work Performing Test Renders You should start at a low quality level and progressively increase quality in a series of test renders to hone in on a high quality result Without using global illumination and final gather, only direct illumination is simulated Direct illumination stops at the first surface encountered by the light rays Unit 10-Rendering & Sharing Your Work Global Illumination Global (or indirect) illumination is simulated by bouncing photons off surfaces in the model After a set number of bounces the photons leave circular splotches The photons illuminate areas not reached by direct light Increase the number of photons/light to improve the quality of global illumination Unit 10-Rendering & Sharing Your Work Final Gathering Final gather can be used with or without global illumination Final gather uses the light intensity distributed throughout the space by global illumination as its starting point Final gather produces the highest quality results but can take a (very) long time to calculate You should only invest the time for final gathering after you have done test renders Unit 10-Rendering & Sharing Your Work Mastering AutoCAD Chapter 25 Managing and Sharing your Drawings Sharing drawings online ePublishing your drawings Getting started with Autodesk 360 Managing your drawings with DesignCenter and the tool palettes Searching your drawing library with Content Explorer Unit 10-Rendering & Sharing Your Work Whether youre a one-person operation working out of your home or one of several hundred Autodesk AutoCAD software users in a large company, file sharing and file maintenance can become the focus of much of your time. In our interconnected world, the volume of messages and files crossing our paths seems to be increasing exponentially. In addition, the Internet has enabled us to be more mobile, adding yet more complexity to file management and data sharing tasks. Unit 10-Rendering & Sharing Your Work In this chapter, youll learn about some of the tools AutoCAD offers to help you manage your files and the files you share with others. Youll also examine some general issues that arise while using AutoCAD in a workgroup environment. You may find help with problems youve encountered when using AutoCAD. Unit 10-Rendering & Sharing Your Work One of the first file management tools youll learn about is eTransmit. eTransmit, lets you quickly collect all your project drawings into a single archive file, or you can store the files in a separate folder for later processing. This collection of files is included with a report file as a transmittal. Unit 10-Rendering & Sharing Your Work Because AutoCAD drawings specify the methods and materials used to produce an object or a building, they are frequently treated like legal documents. After an AutoCAD drawing is issued, its often archived and guarded as a legal record of a design. For this reason, many AutoCAD users are concerned about possible tampering with drawings that are sent to third parties. Even minor unauthorized changes to a drawing can have major repercussions on the integrity of a design. Unit 10-Rendering & Sharing Your Work AutoCAD offers tools that can help minimize file tampering. The eTransmit feature offers a password-protection option to reduce the possibility of unauthorized tampering with transmittal files. AutoCAD also offers password protection for individual files as well as a digital signature feature that helps protect both the author of a drawing and the recipient in the event of file tampering. Unit 10-Rendering & Sharing Your Work There are always associates and clients who need to see only your final drawings and dont care whether they get AutoCAD files. Alternatively, you might be working with people who dont have AutoCAD but still need to view and print your drawings. For those non- AutoCAD end users, AutoCAD offers the Publish feature. Unit 10-Rendering & Sharing Your Work Publish enables you to produce sets of drawings in the AutoCAD DWF format, which is similar to the ever popular PDF format popularized by Adobe. By the way, Publish can also produce PDF format files, though it takes a bit more work. Unit 10-Rendering & Sharing Your Work Whether you share native AutoCAD DWG files or share files using the DWF format, you have a number of ways to convey the files to those who need them. Downloading from websites, transferring via FTP, and exchanging throughare all common methods for sharing files, but they are limited and can leave a user wanting more flexibility..

With Autodesk 360, you can make files available to others in a way that is similar to how you would make files available on an FTP site or a website, with the addition of more easily controlled access. You can track the shared history of a document or set of documents and organize files to suit nearly any project requirement. Categorie s Actions List view Thumbnail view Unit 10-Rendering & Sharing Your Work Autodesk 360 even gives you on-line editing tools for situations when you need to share and modify drawings in collaboration with others. Unit 10-Rendering & Sharing Your Work Even if you dont have to edit drawings, you can share comments about a design document through the Design Feed feature of Autodesk 360. Members of your project can post notes and attach images to drawings. Notes can be associated to specific points in a drawing or other document that youve posted for viewing. Associate this post to an area in the drawing Associate this post to a point in the drawing Attach image(s) to this post Tag in this post Unit 10-Rendering & Sharing Your Work AutoCAD offers DesignCenter to help you keep track of the documents you use in your projects. You can think of DesignCenter as a kind of super Windows Explorer that is focused on AutoCAD files. DesignCenter lets you keep track of your favorite files and helps you locate files, blocks, and other drawing components. In addition, you can import blocks and other drawing components from one drawing to another by using a simple click and drag. Unit 10-Rendering & Sharing Your Work Content Explorer has many features that overlap with DesignCenter, but Content Explorer places an emphasis on searching for data rather than relying on the users own file organization. Content Explorer can look at your drawing files and catalog and index the data that it finds. If you have an extensive library of files, creating this index can take some time, but it occurs in the background so you dont have to stop working. Unit 10-Rendering & Sharing Your Work The most powerful feature of Content Explorer is its ability to find an AutoCAD drawing or element by name. For example, suppose you remember that you created a block last year but youve forgotten the name and location of the drawing where the block was placed. Without Content Explorer, youd have to make a best guess at the file location and just start hunting. This search could take hours. With Content Explorers search feature, you could find the block in minutes. Unit 10-Rendering & Sharing Your Work
