Présentation : 1 Loading an object Figure 1 - 3D Builder Start Screen 3D object can be loaded using 3 different methods. One can either pick a model from the 3D Builder Library, load them from an external file or create a new one from a Kinect v2 Sensor scan see 3D Scanning . Loading an object from a file can be done by pressing the Load icon. 3D Builder currently supports the following file formats 3MF load and save STL load and save PLY load and save OBJ load only VRML load only 2 Camera Movement Action Mouse Touch Rotate Camera Left button drag 1 finger drag Tap gesture illustration Camera pan Right button drag 2 fingers drag 3 fingers drag with zoom lock Camera zoom Mouse scroll Pinch and stretch Pinch and stretch gesture illustrationsPinch and stretch gesture illustrations Focus Double Click Double Tap Double-tap gesture illustration 3 Selection Control Figure 2 - Maximized Selection Control Control Description Shortcut Pressing this icon will restore or minimize the selection tool. N A Select all objects in the scene. CTRL A Deselect all objects in the scene. CTRL D 4 Object Transforms Figure 3 - 3D Builder Toolbar Control Description Shortcut Move mode dragging one of the arrow will move the object in the selected dimension. R Rotation mode dragging one of the arrow will rotate the object around one of the 3 axis whose origin is at the center of mass of the object. E Scale mode dragging the arrow will scale the object following the direction of the arrow. Note rotating the camera can change the side on which the arrow is displayed. This can be very useful to scale an object in a desired direction. W keeps the aspect ratio on Q removes the aspect ratio Edit the value of a move, a rotation or a scale. Note Pressing the unit measure in scale mode will switch it to percentage. SPACE Undo CTRL Z Redo CTRL Y 5 Object Mode Figure 4 - Toolbar with the object mode activated Control Description Shortcut Object Mode activate deactivate the object mode. N A Clone create a duplicate of the selected 3D object. CTRL SHIFT C Delete CTRL X Settle allows the user to position and lay the selected 3D object flat on the print bed. N A Group CTRL G Ungroup CTRL SHIFT G Center View center the camera on the selected 3D object. CTRL O 6 File Mode Figure 5 - Toolbar with the file mode activated 6.1 File Mode General controls ------------------------------- Control Description Shortcut File Mode activate deactivate the file mode. N A Raft displays a rendering of a raft for all the objects of the scene. N A More displays a bottom bar with additional options. Mouse right click Supports displays a rendering of supports for all the objects of the scene. N A 6.2 6.2 Materials ----------------- When the File Mode is active , the material tool appears Figure 6 the user can then add materials to the material tool by pressing and pick his material from the material selection Figure 7 . Then the user can select the object and press a material from the list to apply it. Figure 6 - 3D Builder Material Tool Figure 7 - Material selection Figure 8 List of materials that can be applied 7 Edit Mode Figure 9 - Toolbar with the edit mode activated 7.1 Edit Mode General controls ------------------------------- Control Description Shortcut Emboss enters the emboss mode which allows the user to emboss texts or contour to the selected 3D object. N A Plane cut enters the plane cut mode which allows the user to cut the selected 3D object. N A Simplify reduces the number of triangles used to render the selected 3D object. N A Smooth averages the surface of the selected 3D objects to smooth it. N A Subtract suppress anything that is currently intersecting with the selected 3D object. N A Intersect keeps the intersection of multiple selected 3D objects. N A Merge creates one object by merging multiple selected 3D objects. N A 7.2 Emboss ---------- Figure 10- Toolbar with the emboss mode activated Control Description Shortcut Text Emboss allows the user to input the text to be embossed. N A Contour Emboss allows the user to create an embossment based on an icon or a file. Note contour emboss works best with simple binary icons. N A Plane Projection optimize the embossment for a plane surface. Z Cylindrical Projection optimize the embossment for a cylindrical surface. X Spherical Projection optimize the embossment for a spherical surface. C Accept applies the embossment to the 3D object. ENTER Cancel exit the emboss mode. ESCAPE 7.3 Plane cut ------------- Figure 11 - Toolbar with the plane cut mode activated Control Description Shortcut Move Mode allows the plane to be moved in one dimension. R Rotate Mode allows the plane to be rotated. E Keep Top cut the object and keep only the part on top of the plane. Z Keep Bottom cut the object and keep only the part below the plane. X Keep Both cut the object and keep both parts. C Accept applies the plane cut to the object. ENTER Cancel exits the plane cut mode and discards the operations. ESCAPE 8 3D Scanning 8.1 General controls -------------------- When the scan icon is pressed, a user can perform 3D scans using a Kinect v2 sensor for Windows. To perform a scan, the user must satisfy the below requirements 64-bit x64 processor Dual-core 3.1-GHz 2 logical cores per physical or faster processor USB 3.0 port dedicated to the Kinect for Windows v2 sensor Intel and Renesas controllers 4 GB RAM Graphics card that supports DirectX 11 Windows or Windows Embedded 8 or Windows 8 or 8.1 The user can set the Size detected by the sensor Figure 12 and the resolution of the scan Figure 13 . After each modification of settings or before starting to scan the sensor has to be reset. Once enough data is collected press complete to open the scan in the 3D builder editor. Figure 12 - 3D Scan option Size Figure 13 - 3D Scan option Detail 8.2 Tips for better scans ------------------------- The quality of a scan is affected by 3 major factors The quality of the GPU a high-end GPU will allow for higher frame-rate and will produce better scans. Optimal results are obtained with 20fps or more. The quality of the lighting a setting without any visible shadows will produce the best results. The more diffuse the light is the better the colors will be captured. The background the distance between the background and the object to be scanned should be maximized, this avoids having artifacts from the background to be captured by the sensor. Additionally, non-reflective background works better as reflection will create noise around the scan. Scanning can be performed in two ways, either by moving the Kinect v2 Sensor around the scanned subject. Or by fixing the Kinect v2 Sensor and rotating the scanned subject. The second option has proven to provide the most optimal results when scanning big objects. 9 Video tutorials A tutorial series about 3D builder is available on the Channel 9 - 3D Printing blog 3D Builder Tutorial Part 1 Viewing your first 3D object 3D Builder Tutorial Part 2 Transforming and printing your first 3D object 3D Builder Tutorial Part 3 Object mode and settings 3D Builder Tutorial Part 4 Building 3D objects with edit mode 3D Builder Tutorial Part 5 Scanning with Kinect for Windows
