3D Design: Importing 3D Models

Carveco Tutorial: Importing 3D Models (STL, OBJ)

In this tutorial, we explore how to import, position, and work with 3D models in Carveco using STL or OBJ files. Learn how to scale, rotate, and compose multiple models for machining.

🔹 Differences Between Reliefs and 3D Models

• Relief Clipart (blue) can be freely moved, transformed, and layered.
• 3D Models (e.g. STL) are imported via the Import 3D Model dialog and use specific positioning tools.

🔹 Importing a 3D Model

1. Go to Relief > Import > Import 3D Model.
2. Select your STL or OBJ file from the file browser.
3. Use the dialog box to adjust scale, position, and rotation.
4. Click Center to position the model on the zero plane.
5. Once satisfied, click Paste to place the model.

🔹 Adjusting Model Position and Size

• Scale – Use linked dimensions or unlock to stretch/squash independently.
• Z Position – Drop model to embed in material. Use negative Z to center or sink it.
• Rotation – Rotate in X, Y, or Z axes. Use 90/180 degrees or negative values as needed.
• Copy Placement – While dialog is open, change position and click Apply to duplicate the model.

🔹 Tips for Importing Multiple Models

• Import columns, angels, or other parts one at a time to build scenes.
• Use mirror options in the dialog to flip parts (e.g. angels facing opposite directions).
• Use Paste before importing new parts to lock them into the model.
• Save often and use incremental saves before pasting each model.

💡 Notes on Undercuts and Orientation

Carveco cannot machine undercuts due to 3-axis limitations. When pasting a model, all vertical surfaces are dropped straight down. For proper alignment:

• Ensure correct rotation before pasting.
• Use Merge High mode to blend overlapping reliefs smoothly.
• Use Replace if embedding one model into another relief.
