EXTRACTED REQUEST: I am using a faro arm and some someftware to clean up the point cloud data, it brings in a ref that I can convert to a mesh in solid works but i feel like i am missing a step on getting this cleaned up

USER MESSAGES:
1. I am using a faro arm and some someftware to clean up the point cloud data, it brings in a ref that I can convert to a mesh in solid works but i feel like i am missing a step on getting this cleaned up
2. what if my part isn't coming in normal to an axis
3. In cloud compare i only have the point data, how do i align it
4. where would set as horizxontal be

ASSISTANT RESPONSES:
1. You probably are missing a step — and it is usually not inside [embedded media omitted] itself. The best workflow for FARO arm scan data is usually: 1. Capture 2. Point cloud cleanup/alignment 3. Mesh optimization + hole filling + decimation 4. Convert to usable mesh 5. Import into SOLIDWORKS 6. Reverse engineer actual CAD features/surfaces Most people try jumping from raw scan → SOLIDWORKS mesh too early, and that is where things get painful.. What is likely happening You currently have: - FARO arm scan - Software exports `.ref` - You convert/import into mesh in SOLIDWORKS But the mesh is probably: - too dense - noisy - non-manifold - open surfaces - overlapping triangles - not watertight - uneven normals - j…
2. That is completely normal with scan data. Raw FARO scans almost never come in aligned nicely to X/Y/Z in [embedded media omitted]. The important thing is: - do NOT immediately start modeling on the crooked mesh - first establish a coordinate system/alignment That is one of the biggest missing steps in reverse engineering workflows.. Best practice workflow BEFORE building CAD: You want to: 1. Identify major reference geometry 2. Align the scan 3. Create a clean coordinate system 4. THEN model. Option 1 — Best method (recommended) Align the mesh BEFORE importing into SOLIDWORKS Use: - [embedded media omitted] - [embedded media omitted] - [embedded media omitted] This is the preferred professional workflow.. In C…
3. [embedded media omitted] Depending on the version of [embedded media omitted], you may NOT literally see a button called “Set as Horizontal.” Some tutorials/plugins mention it, but many installs do not expose it directly. The more reliable method is this:. The workflow you actually want 1. Segment a flat face Use the scissors tool and isolate: - bottom plate - table surface - flange - known flat area. 2. Fit a plane Go to: Tools → Fit → Plane Now CloudCompare creates: - a plane object - a normal direction You should see the plane appear in the DB tree on the left.. 3. Use the plane normal to rotate the cloud THIS is the step most people miss. Select: - the POINT CLOUD NOT the plane Then go to: Edit → Apply Tra…
