How to use more than one 3rd party 3D models in VCarve

Overview

This video shows how to import and combine multiple third-party 3D models into one VCarve/Aspire project, enabling composite reliefs and mixed models in a single toolpath.

Steps

1. Open VCarve/Aspire and create a new project with the desired job dimensions.
2. In the Modeling tab, select Import 3D Model and choose your first third-party model (STL, OBJ, etc.).
3. Place the model on the job area and adjust its position, size, and base height if needed.
4. Import the second third-party model using the same Import 3D Model command.
5. Position the second model relative to the first, using alignment tools or manual placement.
6. If the models are separate components, combine them by selecting both and using Create Component or merging them in the component tree.
7. For overlapping geometry, apply Smooth or Merge operations to unify the relief.
8. Proceed with toolpath generation as you would for a single combined 3D model.

Key Points / Warnings

• Verify that all imported models share the same units and scale before combining.
• STL/OBJ models may import as single components; check the component tree after import.
• Different model resolutions (DPI) can slow down processing—resample components to a common resolution if necessary.
• Use Align and Set Base Height tools to avoid models sitting below the material surface.
• Merging components is not always reversible, so save a separate backup file first.
• Some third-party models may contain non-manifold geometry; repair them before importing to avoid artifacts.
