How to Convert OFF to STL with MeshInspector Software

Dealing with 3D geometry in the OFF format? Then file conversion is of importance to you. The MeshInspector program offers a fast, accurate, and user-friendly way to convert OFF models into STLs with perfect geometry preservation. With a few clicks, you will export your project as a solid STL file, suitable for your professional activities.

1

Opening OFF Files

To kick off the OFF-to-STL conversion flow, launch the MeshInspector program. Once our UI is open, head to the ‘Home’ tab. Click on ‘Open Files’ to upload your OFF model.

2

Browsing OFF Files

In the dialog window that appears, find your OFF file. Once it is found, select it. Click ‘Upload’ (or double-click its name). MeshInspector will be quick to load the OFF file.

3

Viewing OFF Files

After import, your OFF model appears as a polygonal surface mesh. It is 100% ready for further processing and editing. Rotate, zoom, or inspect it from any possible angle.

4

Exporting Components

When your OFF model is ready for export, find it in the Scene Tree. Right-click the desired object. Then choose ‘Export’ to open the export dialog and get prepared for STL output.

5

Combining for Export

If the OFF contains multiple objects, merge them before exporting. Select all elements in the Scene Tree, right-click, and choose ‘Group’. Then, right-click the new group and select ‘Combine Subtree.’

6

Setting STL Format

After clicking ‘Export’, our ‘Save File’ dialog will appear. Rename your file if needed and open the ‘Extension’ dropdown list. Choose .stl as the output format. MeshInspector will then perform the OFF-to-STL conversion.

7

Inspecting the Size

Once exported, reopen your STL file in MeshInspector to check its scale. Go to the ‘Inspect’ tab and activate ‘Bounding Box’ to display overall dimensions and ensure your STL model’s proportions are fine for you after conversion.

8

Adjusting the Size

If the STL does not match your expectations in terms of size, navigate to the ‘Transform’ section under ‘Information’. Employ the Scale slider to adjust the size. Once satisfied, confirm your choice. Click the checkmark icon.
