10 Free and useful computer-aided design software computer-aided design (CAD) is a combination of computer programs and systems that allow engineers and architects to design detailed two- or three-dimensional models of physical objects, such as mechanical parts, buildings, and molecules. It specially used to design curves and figures in two-dimensional (“2D”) space; or curves, surfaces, and solids in three-dimensional (“3D”) objects. There are so many “free” CAD programs out there but only a handful are either really free or useful. Here is 10 Free and useful computer-aided design software. 3DVIA Player The 3DVIA Player is a free plugin that plays 3D games and displays 3D models. Use the 3DVIA Player on popular gaming websites or with a 3DVIA Hosting Account to see your models anywhere. Additional Product Plugins
Make a Lego ROV part 2 - the controller We designed a small simple PCB for this controller - you could either use this, or some other semi-permanent breadboard and wire things yourself. The designs and schematic for the controller PCB are Open Source and available to download from our GitHub page - the files include those needed for you to modify the PCB in Eagle CAD, and a zip file of the Gerber files needed to send to a PCB manufacturer if you want to have your own made. Alternatively you can get the PCB (and/or other parts) directly from us using the top link below. For this build you will need COLLADA - Digital Asset Exchange Schema for Interactive 3D COLLADA™ defines an XML-based schema to make it easy to transport 3D assets between applications - enabling diverse 3D authoring and content processing tools to be combined into a production pipeline. The intermediate language provides comprehensive encoding of visual scenes including: geometry, shaders and effects, physics, animation, kinematics, and even multiple version representations of the same asset.COLLADA FX enables leading 3D authoring tools to work effectively together to create shader and effects applications and assets to be authored and packaged using OpenGL® Shading Language, Cg, CgFX, and DirectX® FX. COLLADA at a glance COLLADA defines an XML Namespace and database schema to make it easy to transport 3D assets between applications without loss of information, enabling diverse 3D authoring and processing tools to be combined into a content production pipeline.

untitled Presenting 3D content interactively on the Web is still quite challenging nowadays and requires highly technical knowledge to make it accessible easily to a wide audience. At Sculpteo, we developped our own online 3D viewer to address this issue, using multiple technologies (Flash, Java, WebGL, raytracing) to ensure the 3D content could be delivered in any situation, without requiring the latest browsers or plugins. Simple integration The 3D viewer may be integrated to any external web page using a <iframe> tag, like so: This will create a 250x310 zone in the page where the design will appear, like so: In this case, the design was already uploaded to Sculpteo’s website, and is identified by the number “228271701558722584600696525325323037491”.
