Key Features and Capabilities of Micrsoft 3D Builder
User-Friendly Interface
Unlike many advanced 3D applications that present new users with a steep learning curve, 3D Builder uses a touch-friendly interface designed specifically for simplicity and ease-of-use. All of its core tools are accessible from a compact ribbon toolbar at the top of the window. It uses familiar Windows UI elements like large toolbar icons and context-sensitive right-click menus.
The clean workspace displays your object on a backlit grid, making it easy to position and work on it from any angle by orbiting around using click-and-drag mouse motions. Helpful on-screen tips are displayed for each tool to explain how it works.
Built-in Tutorials
Recognizing that many Windows users may be unfamiliar with 3D modeling software, Microsoft built a set of interactive tutorials directly into 3D Builder. These tutorials cover the basics of navigation, building objects, using scans, and 3D printing preparation.
Robust Mesh Editing Tools
While the interface is simple, 3D Builder provides a full suite of polygon mesh editing features for working with 3D models. You can easily add, delete, move, and scale 3D vertices (points), faces, and objects. Advanced tools like Push/Pull, Flip normals, and Intersect allow you to manipulate more complex shapes.
The incorporated mesh analysis tools like Inspector and Stresses let you optimize objects by identifying and correcting potential 3D print problems like holes, disconnected components, degenerate geometry, and more. There are also smoothing, remeshing, and mesh simplification tools available.
Built-In Image Texturing
Applying surface textures to 3D objects enhances realism. With 3D Builder you can easily map an image file like JPEG, PNG, or GIF directly onto your object as a texture. You can adjust positioning, scaling, and wrapping to fit. This lets you simulate materials from woodgrain to checkerboards without needing to master complex texture mapping techniques.
Scanning Real-World Objects
One of 3D Builder’s most powerful features is its ability to generate 3D models automatically by scanning physical items in the real world. To use this function you will need a compatible 3D camera peripheral like Microsoft’s Kinect sensor or Asus Xtion PRO. Simply connect your scanner, calibrate it, and use the Scan function to capture multiple angles of the object. 3D Builder will process the images into a 3D model you can further edit and enhance.
Integration with 3D Printing Platforms
Once your 3D model design is complete in 3D Builder, you can connect directly with third-party 3D printing services like Shapeways, Sculpteo, and MakeXYZ to order a real-world physical reproduction of your object via additive manufacturing. The straightforward process lets you upload your model, choose printing materials like plastic or metal, pick a scale, and buy your print.
Seamless Interoperability with Other 3D Tools
3D Builder uses industry-standard CAD file formats like STL, OBJ, 3MF and more for importing and exporting 3D models and scans. This cross-compatibility allows you to use its powerful and easy modification tools alongside more complex CAD software. You can also import SVG 2D files and extrude them into 3D objects.
Getting Started Guide
Let’s run through the basics of using Microsoft 3D Builder by modeling a simple 3D house object. This will demonstrate the key functionality and workflow of building objects in 3D Builder.
Step 1: Launch 3D Builder
Open 3D Builder from the Start menu or search bar in Windows. You can also launch it from the Apps list in Windows settings. The application will start up and display the Home screen.
Step 2: Navigate the Interface
Look at the top Interface Ribbon which gives you access to all the main functions via simple icons and labels separated into the Home, Insert, Modify, Make and View tabs.
The left-side ViewCube lets you easily reorient your perspective on the object by clicking preset isometric angles. The Zoom tools at right control magnification level.
Step 3: Create a Base Shape
Go to the Home tab and select the “Box” icon. This enters object placement mode where you click to set the start point and drag to set dimensions. Draw a 20×20 meter square base. You can see dimensions in the bottom status bar.
Step 4: Push/Pull Walls
Now go to Modify > Push/Pull to extrude 3D shapes. Click and drag upward on the base to pull up vertical walls 10 meters high. Click again and drag inward on left and right walls to add depth.
Step 5: Add Windows
Select the front face of one wall, go to Insert > Hole to make an opening. Adjust the bounding box to create a 2×2 meter window. Copy and paste twice more to add additional windows.
Step 6: Add Door and Roof
Use Push/Pull on the back wall to create a centered door opening. On top edges select Modify > Roof to automatically add an angled roof 3 meters high. Adjust points to taste.
And there you have it! A simple 3D house model built in just a few clicks. You can now orbit and pan around your model using click+drag mouse controls to view from any angle.
The final step before 3D printing would be going to Prepare > Validate to check for and correct any geometry issues in your model automatically. Then go to Make to order from third-party printing services.
Advanced Functions
3D Builder offers many powerful advanced mesh editing and construction tools to provide finer control over your 3D designs. Let’s look at a few examples and how they can help take your 3D models to the next level.
Modify Tools The Modify tab in the ribbon toolbar holds the more advanced editing tools. These allow you to easily adjust parts of your model or combine shapes in new ways.
Push/Pull – The push/pull tool lets you click+drag on any face or edge to extrude outward or inward, stretching your object. This enables fast and intuitive shape creation.
Edge Slice – Insert diagonal edge loops onto faces to increase geometry density for greater smoothing or detail.
Vertex Merge – Automatically merge multiple vertices into one point to optimize models.
Flip Normals – Fix surface facing directions to set inside vs outside faces properly for printing solid objects.
Remesh – Retriangle and rebuild your polygon mesh with higher density meshes for adding detail.
Construct Tools
The Construct dropdown provides advanced solid geometry editing functions. These are useful for precision modeling and design.
Intersect – Combine two objects to make a new solid shape representing only their intersecting volume.
Hollow – Shell out the interior of a solid object leaving only the outer skin intact. Adjust thickness.
Plane Cut – Slice your model along a line plane, dividing it into two parts.
Improve Detail Tools
To enhance shapes and correct issues, these tools modify your mesh at a structural level.
Refine – Increase mesh triangle density to achieve smoother surfaces and finer details throughout your 3D model.
Stresses – Detect weak structural areas prone to printing errors. Automatically generates sparse reinforcement struts.
Simplify – Decimate mesh triangles while preserving geometry to optimize models for 3D printing as solid objects. Reduces file size.
Repair Tools
Identify and fix models manually or automatically to comply with 3D print standards.
Inspector – Check models for common 3D printing errors like holes, gaps, disconnected components, thickness, orientation issues, and more. Guided fixing tool suggests quick repairs.
Validate – Runs a full automated printability analysis on your model and attempts to repair any outstanding issues so you can confidently send the model to print.
3D Model Files
3D Builder can import and export all standard 3D model file formats like OBJ, STL, PLY, 3MF, and more. This cross-compatibility allows you to integrate its easy editing tools into any 3D design workflow alongside other modeling software.
STL Format (.stl) – The preferred format for 3D printing applications. Supports both ASCII and Binary variants. Exports 3-sided mesh triangles.
OBJ Format (.obj) – An open geometry definition format popular in 3D graphics applications. Stores 3D models as groups of vertices, edges, and faces.
3MF Format (.3mf) – Stores 3D models with optional color, textures, material properties, and more in an XML-based format that supports CAD & 3D printing. Developed by Microsoft and partners.
3D Scanning Guide
A standout feature of 3D Builder is its built-in support for 3D scanning real-world objects. With compatible hardware like Microsoft’s Kinect sensor, you can capture 2D image arrays of an item from multiple angles. 3D Builder then processes these image captures into a 3D model automatically.
The scanning process is simple – connect your scanner, calibrate, set your scan volume, and control capture feeds manually or automatically with turntable mode for consistent results. But properly setting up the camera and positioning the object takes some practice for clean scans. Here are some tips:
Scanner Positioning Place scanner atop a sturdy platform like a tripod to prevent shifting during scans. Position it about 12 inches away from scanning volume, roughly central to your object turntable. The scanner must view the object from a 40 degree vertical angle downwards.
Object Placement Center your object on the scan turntable elevated at least 3 inches off the surface. Choose contrasts backgrounds and avoid noisy patterns. Rotate object slowly during scanning. Use props to angle objects. Remain still while scanning in room.
Scan Settings
Start with presets designed for your scanner then adjust settings as needed. Increase scan resolution for finer details – but keep processing requirements in mind. Use wider scan volumes for larger objects. Set the number of scan loops based on object complexity.
Scan Processing
After completing captures, the image data will process into a 3D model. Larger scans may take significantly longer. The final mesh will need cleaning of disconnected components and filing any remaining small holes. Complex objects may require multiple scan sessions for full coverage.
By leveraging 3D scanning you can rapidly generate highly detailed 3-dimensional models of existing items for archival, custom reproduction, or just for fun. It opens up new possibilities for digitizing antiques, sculpture, architecture elements, and more.
Example 3D Models
Now that you have a handle on 3D Builder’s core tools for constructing objects manually as well as scanning items, let’s run through some examples of practical models you can create and customize as great introductions to leveraging this powerful CAD software in your own projects.
