1. What options should i use here to get a clean mesh

ASSISTANT RESPONSES:
1. For a good first-pass mesh, I would use: - Mesh Triangle Size: `0.030 in` — a good starting point for normal fabricated parts. - Smooth Mesh: Checked. - Show Mesh Preview: Checked. - Scan Inside Containment: Checked, with the containment box kept fairly tight around the part. - Clip Plane: Use this to remove the table, floor, fixture, or anything underneath the part. - Plane Clipping Offset: Start at `0.050 in`; adjust until the unwanted surface disappears without cutting into the part. - Flip Plane Directions: Only check this if it removes the part instead of the background. The most important warning is that a smaller triangle does not automatically create a cleaner mesh—it mostly creates a much larger and n…
2. Those advanced settings look reasonable, but I would make them slightly more conservative so the software doesn’t erase real edges or bridge actual holes. Use this starting setup: - Laser angle scan filtering: about 35–40% toward More - Spike filtering: about 30–40% toward More - Maximum scan gap: change from `0.120 in` to approximately `0.060 in` - Mesh triangle size: keep `0.030 in` - Smooth mesh: checked The `0.120 in` maximum gap is four times your triangle size. It could connect across small missing areas that should remain open. At `0.060 in`, it can bridge minor scan dropouts while being less likely to distort holes, slots, and edges. If the preview still shows: - Random spikes or whiskers: increase Spi…
