How to Create 3D Models in Paint 3D

How to create 3D models in Paint 3D

1. 1Start with built-in shapes

   

   Open a new project and select 3D shapes. In the right pane, choose a built-in object such as a cube or sphere. Click or drag in the workspace to place it. Give the part a color so you can distinguish it from anything you add next. For a simple rocket, begin with a cylinder for the body and use a cone for the nose. Treat each part as a separate object until you like the alignment.

2. 2Draw a custom part with 3D Doodle

   

   In 3D doodle, pick a soft or sharp edge style, depending on how rounded you want the result. Trace a simple outline and close the loop to turn it into a solid object. The video shows a blue doodle raised from its outline. Start with a shape that has few corners. Once it forms correctly, select it and check the edge and silhouette before adding more detail.

3. 3Rotate and assemble your objects

   

   Select an object and look at the handles around it. Use the rotation handles to turn the part and the depth control to move it forward or backward. Switch to 3D view to inspect the joins from the side. Shapes that overlap from the front can still be far apart in depth. Once the parts line up, use multi-select and Group if you want to move the assembled pieces together.

4. 4Save the project and export the model

   

   Choose Menu > Save as. Save a Paint 3D project to keep an editable version inside the app. Choose 3D model when you need a model file, then select from the formats available in your installation. If you need a shareable picture, choose Image. Open the exported model in its destination app to check that the geometry, view, and materials look as expected.

A simple first model to try

Make a little tower with a cylinder, a cone, and a sphere. Keep the cylinder upright, align the cone above it, and add the sphere as a separate detail. Give each piece a different color while arranging it so you can spot overlaps. Inspect from the front and side before grouping. Recolor the pieces after the proportions and positions look right.

Frequently asked questions

Why do my pieces look connected from only one angle?

The objects can line up on the screen while sitting at different depths. Use 3D view to look from the side. Select each piece and move it along the depth axis until the join looks right. Check another angle before grouping or exporting.

Does saving an image preserve the model?

An image export captures a flat view of the artwork. Save an editable Paint 3D project when you want to return to the arrangement. Use 3D model export for a file intended for another 3D application, and check which formats your version and destination app share.
