Fixing Geometry Errors with Manual Tools in Materialise Magics

General tips:

• You'll find most manual fixing tools in the Fix ribbon or in the manual options on the fixing pages.
• Refer to the Part Fixing Info tab in the right-side panel to identify errors in your part.
• If you're not sure what to do next, check the suggestions under Advice in the Part Fixing Info tab.

Inverted normals:

1. Select the Mark Triangle icon in the bottom panel and choose the triangles on your model you'd like to invert.
2. Click the Invert Normals icon in the Fix menu.
3. If no triangles are marked, this function will invert all triangles in your part.
4. You can use the semi-automatic fixing tool, represented by the wrench icon in the Part Fixing Info tab, to quickly fix all inverted normals.

Near bad edges:

1. Navigate to the Near Bad Edges page by clicking the cube icon with an orange highlighted corner on the right-hand side.
2. Review the stitching tolerance, which Magics estimates automatically, and adjust the Max gap size if necessary.
3. Set the desired number of stitching Iterations and click Stitch to perform the operation.

Holes:

1. Click the Hole tab in the same fixing pop-up as the Near Bad Edges page.
2. For planar holes: select the Planar icon. Then, click Fill hole mode and select the contour of the hole on your model.
3. For holes with two separate contours: check the Treat as one hole option, click Fill hole mode, and select the two contours of the hole on your model.
4. For complex triangular holes: select the Create triangle function to create a single triangle.
5. For curved holes: select the Ruled icon. Choose User defined and the pencil icon to define a direction for the hole fixing scan, then click Fill hole mode and select the contour of the hole.
6. For irregular holes: select the Freedom icon, click Fill hole mode, and select the contour of the hole.
7. For the remaining holes in the list, it's best to fix them in the Triangle tab. There, click Unify to remove unnecessary triangles and correct the geometry.

Noise shells:

1. In the fixing pop-up, navigate to the Shell page.
2. In the list, you may see multiple items. The first is typically the main model. The second likely has few triangles and is therefore a noise shell.
3. Select the noise shell, and press the Delete key on your keyboard to remove it.

Intersecting triangles:

1. In the fixing pop-up, navigate to the Triangle page.
2. Try filtering sharp triangles by clicking Collapse.
3. You may notice that extra noise shells appear. Use the semi-automatic fixing tools, represented by a wrench icon in the Shells row of the Part fixing info tab, to remove them.
